Brain Tumors in Dogs and Cats
Primary vs Secondary Brain tumors can be primary or secondary (metastasis from other sites). Primary brain tumors are usually solitary, the most common ones in the dog being gliomas and meningiomas. In cats, the most common type are meningiomas and these can occur at multiple locations. Secondary tumors in dogs include extension of a nasal tumor, metastases from breast, lung or prostate cancer, hemangiosarcoma or extension of a pituitary gland tumor.
Nerve sheath tumors and skull tumors have also been reported. Secondary tumors in cats include pituitary gland tumors, metastatic carcinomas, local extension of nasal tumors, skull tumors and middle ear cavity tumors. What causes a brain tumor? The cause of brain tumors is not known. Diet, environment, chemical, genetic, viral, immunologic and trauma have all been considered. In cats with meningiomas, because they often occur in very young animals, a genetic element is suspected.
Benign vs Malignant
The terms benign and malignant must be used with care when referring to brain tumors. Normally these terms apply to various characteristics on a cellular level, but on a biological level, even benign brain tumors can kill the animal due to the secondary effects like increased intracranial pressure or cerebral edema. In short, any brain tumor can kill. What are the symptoms? There can be huge variety here. Many animals will present with vague signs, such as one or several of the following:
1. Loss of trained habits
2. Decreased levels of activity
3. Decreased frequency of purring in cats
4. Disorientation
5. Confusion More specific symptoms are dependent upon where exactly the tumor is located within the brain, the size of the tumor and how quickly it is growing. As a tumor enlarges, symptoms tend to become more severe.
These can include:
6. Seizures (often indicate a tumor in the cerebral cortex)
7. Facial paralysis (may indicate a brainstem tumor)
8. Tremors (may indicate a tumor in the cerebellum)
9. Wobbliness (may indicate a tumor in the cerebellum)
10. Full or partial blindness (may indicate tumor in hypothalamus or optic nerve)
11. Loss of smell (may indicate tumor of olfactory system) The physical presence of the tumor can cause knock on effects due to inflammation and edema of the surrounding area. This can cause symptoms such as:
12. Changes in behaviour or temperament (irritability, lethargy)
13. Compulsive walking
14. Circling
15. Pressing head against a wall or hard surface Animals can sometimes carry brain tumors for several years before presenting to a veterinary clinic, if the tumor is slow growing. In these cases the symptoms develop gradually, and the owner tends to get used to them so that by the time the animal is examined, the tumor has reached a considerable size. How is a brain tumor diagnosed?
History and Clinical Examination
The first step for a veterinarian is to take a thorough history of all of the clinical signs, and when they developed. This is followed by a full general clinical examination and a full neurological examination. Bloods After that, blood should be taken for routine haematology and biochemistry profiles. This is to look for any disease outside the brain. Results will be normal for brain tumors, with the possible exception of some pituitary gland tumors.
Radiography
Plain skull radiographs (xrays) under general anesthetic have little value in detecting a brain tumor, but they can be useful if there is a tumor in the nasal cavities or the middle ear which could extend into the skull. On rare occasions, they can identify bony changes in the skull which can accompany a brain tumor, or mineralization within the tumor itself. Radiographs and ultrasound of the chest and abdomen are useful to look for a tumor elsewhere in the body, in cases where the brain tumor is a secondary metastasis.
MRI and CT Scans
Confirmation of a brain tumor can is usually only achieved using the advanced imaging techniques, CT scans or MRI. Both of these have pros and cons when compared to one another. CT is better for bony changes, while MRI is better for soft tissue definition, for the detection of many of the knock on effects of brain tumors such as edema, cysts and bleeding. MRI is the preferred option for diagnosing primary brain tumors.
Biopsy
This is the only way to definitively diagnose a brain tumor. The advanced imaging techniques above offer much information, but they can occasionally confuse a tumor with a non cancerous mass or a cyst, and they also do not tell us the exact type of tumor present, and therefore the appropriate treatment and prognosis. The best type of biopsy is the CT guided stereotactic brain biopsy system, which is rapid, accurate and quite safe. Since exploratory surgery is high risk, it is not usually attempted unless there is a reasonable chance of removing the whole tumor with minimal collateral damage.
Many brain tumors in cats and dogs are not categorized on a cellular level until post mortem.
Cerebrospinal Fluid (CSF) Analysis
CSF analysis is useful for ruling out inflammatory causes of the symptoms, but tumor cells are rarely identified here. Increased levels of white blood cells and increased protein levels may be present in the CSF with many brain tumors, though this is not diagnostic. This test can be high risk when intracranial pressure is increased, as brain herniation can occur.
Treatment
Treatment is aimed at being either curative or palliative. Curative treatment eradicates the tumor or reduces its size, whilst palliative therapy reduces the surrounding cerebral edema and slows down the growth of the tumor. Palliative therapy also involves administering antiepileptic drugs, if seizures are occurring as a result of the tumor.
Surgery
Whether this is an option depends on the general health of the animal, and the precise location, size, extent, invasiveness and nature of the tumor. Tumors such as meningiomas in cats can be removed successfully by surgery. However, surgery to remove tumors in certain locations such as the brainstem can be extremely dangerous, possibly resulting in death. Even partial removal can benefit the animal though, particularly if the tumor is slow growing.
Radiotherapy
This is probably the most widely used form of treatment for brain tumors. Radiation therapy can be used alone or in combination with other treatments. It is also useful in the treatment of secondary brain tumors. The aim is to destroy the tumor without harming the normal tissue too much.
Chemotherapy
The main problem with chemotherapy for brain tumors is that many drugs do not cross the blood brain barrier. In addition, the tumor may only be sensitive to high doses, doses which are toxic to normal brain tissue and therefore unsuitable for use. However, several drugs have been used for this purpose that can cross the blood brain barrier with reported success, including cytosine arabinoside, lomustine and carmustine.
Probable Outcome
Studies of animals that receive palliative treatment (corticosteroids) for brain tumors show a survival range post diagnosis of 64 to 307 days. This demonstrates the inability to accurately predict life expectancy in these cases. What is certain is that the survival times significantly increase with surgery, radiotherapy or chemotherapy. Radiation therapy seems to offer the best results, alone or in combination with other treatments. Generally, the more severe the symptoms, the shorter the life expectancy.

A Horse Training Secret From The 1800's To Teach A Horse
Horse owners who are history buffs may recognize the name Jesse Beery. Beery was an enormously famous horse trainer from the 1800's and early 1900's.He learned to train horses at a very young age. It was clear he had a gift for horse training and made it his life's work.
Among the almost countless things Beery could do with a horse, he taught them tricks. One of the most amazing tricks he taught was teaching a horse to drive without lines. (In layman's terms, you have no long reins (known as lines) connected to the horse. The only connection to the horse is the buggy hitched to the horse) This trick almost defies belief!Beery said this about driving a horse without lines: "While I do not advocate it as being a universally practical way of driving a horse, yet it is possible to so thoroughly train the horse to certain signals that he can be controlled more reliably under excitement and in case of danger than it would be possible to manage him with bridle and lines."Beery says there are a number of ways to teach this to a horse but suggests his method as the most reliable.
In a nutshell, Beery first turned his horse loose in an enclosure about twenty-five feet square. He would walk in with a whip and teach the horse to have confidence in him and not fear the whip. (The horse is never whipped).
Once the horse has learned to come to handler at the command of "Come Here" and shows no fear of the whip while it's gently waved over his head and body, and will follow the handler all about the ring, then you have laid a good foundation for further instruction.
Put the horse away until the next day where the horse learns signals of the whip. That process is as follows: Stand close the the horse's hip and take a short whip and tap lightly on the right shoulder until the horse, in anticipation of driving a fly off, will swing his head around to where the tapping is. Step forward quickly and hand him a few oats, or a small piece of apple, almost in the act of turning his head around. Step back and continue the tapping and rewarding. After a while, in his eagerness for the reward, he will take a step or two to the right when the tapping begins. Then caress him and treat him very kindly for that act. Soon, the idea will be conveyed that when tapped on the shoulder the horse will know to turn in that direction.
Remember to train both sides of the horse.Once both sides are trained now an open bridle can be put on. Use short lines that come back as far as his tail only - but they are used only if he becomes unruly or to convey your idea to him.
The handler's whip should not be over five feet long at this stage and the handler should stand directly behind the horse. (Beware of kickers) Let the whip extend to about the middle of his mane. The signal you wish for him to stop for is raising the whip and holding it in a perpendicular position. Associate the meaning of this movement, and position, just as the whip is raised so the horse can see it. Pull hard on the reins and say "Whoa" - all at the same time. After a few repetitions the horse will know what to do. (Assuming you have thoroughly educated your horse to whoa)
The first few times he stops without a pull of the reins step forward and reward him immediately. Much of the success of teaching this trick depends upon how you give the rewards. If the reward is given in a manner so that the horse can fully comprehend it was complying with the handler's wish, it will greatly enhance fixing this impression on the horse's brain.But if not given in the right manner, the reward will be worse than none at all. In the same manner, the horse is taught to turn left and right. This is done by giving the horse a pretty smart tap on the lower part of the shoulder and immediately place the point of the whip three or four feet in that direction. Should he attempt to jump and go ahead too much, you can hold him in check with the action and signal to stop him.

Paws & Pesticides - a Deadly Combination
Toxic pesticides are considered an active poison. They are extremely dangerous to your health, your pets health and our environment.Every year, thousands of domestic pets and wild life lose their lives to the ravaging effects of pesticide poisoning. Most pet lovers also enjoy gardening and the great outdoors. Little do they know what caustic ingredients are in the pesticides that are being sprayed on lawns and green areas. We take for granted that most herbicides used by gardeners or sold in stores are safe. Many name brands such as "Weed n' Feed" and "Round Up" contain the same deadly cancer causing ingredients that were found in Agent Orange. Another synthetic poison found in these two well known garden products is 2,4-D. It is also the active ingredient found in "Killex." It can cause loss of reflex in humans along with comas, kidney and liver failure. In dogs it is the number one killer causing malignant lymphomas, a form of cancer.
Sadly, just five percent of pesticides reach their target weeds and garden pest. The rest are absorbed into our earth, targeting our water supplies through a process called run off or simply just dissipates into our air. Major health damage can occur when Toxic Pesticides are absorbed through our skin, swallowed or inhaled. When not applied correctly, pesticides can settle on ponds, pools, children's toys, pets left outdoors and even drift through open windows settling on our furniture, bedding and even our floors. This deadly poison is often tracked into our homes by our shoes and pets paws.We all face the continuing problem of toxic by-products through years of pesticide residue that is in our food supply and everyday environment. What we don't realize is how wide spread pesticide poisoning really is. These caustic chemicals are virtually used in all of our public buildings including our children's schools and play yards, restaurants, hospitals, hotels and private homes. Pesticide abuse is used in our agriculture and forest areas.
Why are Pets Vulnerable to Pesticide Poisoning?
* Pets spend most of their time close to the ground, this is where pesticide concentration is highest.
* Pets ingest most pesticides while grooming themselves. Any contact with chemicals connect with their fur and paws and is then ingested by the pet.
* Pets spend more time outside and play in heavily treated areas.
* Pets have higher absorption rates than human systems. Animals may be more sensitive and easily poisoned by conditions deemed safe to people.
Signs of Pesticide Poisoning In Pets
* Excessive drooling and foaming at the mouth.
* Loss of thirst and appetite.
* Vomiting or diarrhea.
* Immune function decline.
* Convulsions and disorientation.
* Birds and fish die due to toxic runoff in our water supply.
* Feline thyroid disease.
* Dogs contract cancer (malignant lymphoma)
What Can We Do To Stop Pesticide Poisoning?
* Adapt an alternative "green" solution for pest control.
* Enjoy your weeds and bugs. They are part of nature.
* Educate yourself about pesticides used by your HOA, Lawn Service and immediate neighbors.
* Do not allow your pets to drink from ponds or outside water sources - always keep fresh, clean water readily available.
* Leash your pets, allowing them to run free is not a good idea.
* Bathe and brush your pets often.
* Wash down your outdoor living area.
* Think eco-conscious when dealing with your environment.
Protect yourself and your pets from synthetic pesticides by being an educated consumer and willing activist in our eco-system.

Aromatherapy for Animals, Part 1
For humans and animals alike, essential oils are powerfully antiseptic, detoxifying and revitalizing, thus increasing resistance to disease while strengthening the immune system. Essential oils can also be used to control pet odors and to purify the air from dust, dander and allergens. For example, mix 50 drops of lemon essential oil in a 2-oz spray bottle filled with water. Shake very well several times and spray the room. You'll notice immediately that it refreshes and cleanses the air!
But aromatherapy offers more than just fragrance. Their remarkable actions upon animals -- most notably dogs, cats and horses -- are immediate, profound and long-lasting, positively affecting their overall health and emotional well-being.
Today we will focus on recipes and tips for Fido. As faithful friends, dogs bring affection, pure joy and loyalty into our lives. Most breeds thrive in the outdoors, running and playing in the freedom of nature. In fact, dogs will naturally purge their system in the wilderness, carefully choosing specific plants their systems need, such as blackberries, raw carrots, etc. Now a domestic animal, most dogs have lost this natural instinct, and are becoming less resistant to illness in general.
Dogs have a predictable set of physical ailments that may occur during their life span. Today I'll share aromatherapy blends that will soothe and heal skin problems, remove and prevent fleas and ticks, relieve the pain of rheumatism and arthritis, revive energy and control pet odor.
******** Blend to Relieve Skin Problems ********
Pour the following essential oils into a 10-ml bottle and fill with Calendula oil. Apply to afflicted area.
-5 drops Lavender -6 drops Geranium
******** Blend to Relieve Itching ********
Pour the following essential oils into a 10-ml bottle and fill with Calendula oil. Apply to afflicted area.
-4 drops Lavender -5 drops Geranium -3 drops Roman Chamomile
******** Blend to Combat Fleas ********
Fleas are nuisances for man and animal alike. This sinister pest hides within your pets' fur as well as in our carpets, parquet and window coverings.
Prepare the following blend by pouring the following ingredients into a 1-oz spray bottle:
-7.5 ml Mint essential oil -22.5 ml rubbing alcohol
Fleas absolutely dislike mint! Spray the affected areas of your home. Don't forget your dog's bed. Spray directly onto your dog, holding the bottle about 10 inches from him. Avoid spraying on the head and eyes.
******** Blend to Combat Ticks ********
Check your home and pet for ticks - look in his bed, window coverings, walls, etc. Burn the ones you find to prevent them from coming back.
Prepare the following blend by pouring the essential oils into a 10-ml bottle and adding organic vegetable oil to fill.
-10 drops Tea Tree -10 drops Lavender
Apply 1 drop of Lavender and 1 drop of Tea Tree undiluted essential oils before extracting ticks from your pet. This will disinfect the inflamed area. It may sting a little bit (as alcohol would) but it works great!
******** Blend to Ease Rheumatism ********
Like humans, many dogs suffer from rheumatism as they age. Your veterinarian may treat him with specific medications or natural therapies. But locally, you can apply and massage the following blend in the morning and night to alleviate pain.
Prepare the following blend by pouring the essential oils into a 10-ml bottle and adding organic vegetable oil to fill.
-8 drops Birch -8 drops Juniper -7 drops Rosemary
******** Blend to Ease Arthritis ********
As recommended by some veterinarians, soften your dog's bed to make it very cozy and warm. If your dog is an "outside" pet, allow him to sleep inside. A little moist heat, applied directly over painful joints, can be a great comfort to arthritic pets. Get him a warm sweater, or apply a moist heating pad. And massage the area twice a day with the following blend to soothe the pain away.
Prepare the following blend by pouring the essential oils into a 10-ml bottle and adding organic vegetable oil to fill.
-12 drops Birch -8 drops Juniper -7 drops Rosemary
******** Blend to Boost His Energy ******** Prepare the following blend by pouring the essential oils into a 10-ml bottle and adding organic vegetable oil to fill. Massage the spine gently. Use in the mornings only.
-5 drops Rosemary -6 drops Lavender -2 drops Peppermint
******** Blend to Control Pet Odor ********
Try this natural and aromatic spray. Pour the essential oils into a 1-oz spray bottle filled with water. Shake very vigorously several times before each use. Spray directly onto your dog, holding the bottle about 10 inches from him. Avoid spraying on the head and eyes.
-10 drops Lavender -10 drops Geranium -6 drops Lemon

What to Consider when Purchasing a New Dog Bed
There’s no sense in buying a new bed every month as they grow. Secondly, you should observe your dog’s behavior when he or she is sleeping to find out what their preferred position is.
Whether you dog likes to curl up or stretch out will help determine what shape of bed to consider. If your dog curls up, a round or oblong bed with raised sides may be more comfortable for them. On the other hand, if your dog likes to stretch out while sleeping, a flat rectangular bed could be a better option. Look at all the options and try to picture which one would accommodate their sleeping behavior the best. Other factors to consider are the type of material used for the bed. Most dog beds today are made with non-toxic filling, but it’s always a good idea to check the material used for the entire to bed to make sure that if your dog does try to destroy the bed and ingests some material, it won’t be toxic to him or her. Also, your dog’s activity level and location of the dog bed will contribute to what type of bed you will need. If your dog is allowed to frolic in the backyard and come in muddy to his bed in the laundry room, you will most certainly want a washable, durable cover. Some detachable dog bed covers are even moisture and dirt resistant.
An indoor dog that sleeps on your bedroom floor will not need such a heavy duty bed.
After you determine the size, shape and material needs of your dog bed, you can consider what colors and patterns will go with your own home décor. You can be assured that if the dog’s bed is comfortable and appropriate for his or her size and shape, they won’t be picky about the color.

If you own a big house with a spacious garden, outdoor cat houses might be the way to provide with cat with proper housing in a safe environment.
Outdoor cat houses should be very sturdy and safe; preferably made of durable non toxic materials. They should protect your cat from rain, cold, wind and snow if it comes to that.
On the other hand, they should not be excessively warm and they should be able to adapt to warmer weather. Remember that the cat should always feel conformable inside his own house, so he won’t need to wander outside in order to find a comfortable place to stay. Most outdoor cat houses are made of isolated wood, which should have received a specific treatment to make them water and wind proof. They usually contain vinyl doors, in order to make it easy for your cat to go in and out and still keep the outdoor cat house warm and protected. The floor should also be taken care of in a proper way, in order to isolate the complete house. If you really want to add a special treat to your cat, you will be amazed at the amount of outdoor cat house toys you can find, to put inside your new cat house and give your cat another good reason to keep coming back to his safe place.
Other popular outdoor cat houses include models made of synthetic materials that are specifically fabricated to withstand very cold or very warm weather. When buying synthetic outdoor cat houses make sure they are not made of toxic materials and that they are actually safe for your cat. There are several outdoor cat houses available in the market today, and by doing a market research you will see you can find the perfect one within your budget as they come in all sizes and types of finishing’s.
You can go for a more modest version or, if you have the financial means, there are several luxury outdoor cat house models available.
Cats are free and independent animals. They are feline hunters by nature and they were not made to be kept inside the house at all times. Keep your cat happy by providing him the opportunity to be free and safe at the same time. If he knows that by coming back he will find a perfect and safe place to be, he won’t need to go wondering for comfort. Outdoor cat houses are a great choice for the true cat lovers.
