Valium is most commonly used as an injection for pets in status epilepticus, which is a state of active, ongoing seizures, but is not usually used as a sole medication for treating dogs with epilepsy.

Natural Treatments
There are several natural therapies to assist pets with epilepsy. Every doctor has his own favorite regimen; I've included some of the different therapies that I commonly employ in treating epileptic dogs.

Natural diet
A number of pets with epilepsy have been reported to show improvement upon dietary manipulation. Suggested dietary changes (which may decrease a food hypersensitivity that causes the pet to seizure) include: diets free of red meat, homemade diets free of common dietary allergens (beef/chicken/corn,) diets free of preservatives, and diets using minimally processed foods. Some pets may also be sensitive to the flavoring in monthly or daily heartworm preventative medications; using a non-flavored product may also be helpful when dietary manipulation alone is not successful. Since seizures are a medical problem, owners should not try dietary manipulation without a proper diagnosis and veterinary supervision.

Choline/Lecithin
Lecithin contains a substance called phosphatidylcholine (PC) that is presumed to be responsible for its medicinal effects. Phosphatidylcholine is a major part of the membranes surrounding our cells. However, when phosphatidylcholine is consumed it is broken down into choline rather than being carried directly to cell membranes. Choline acts like folic acid, TMG ( trimethylglycine), and SAMe (S-adenosylmethionine) to promote methylation. It is also used to make acetylcholine, a nerve chemical essential for proper brain function.

Choline and phosphatidylcholine are effective for treating human neurological disorders with presumed choline deficiencies including tardive dyskinesia, Huntington's chorea, and Friedreich's ataxia.

For use as a supplement or a food additive, lecithin is often manufactured from soy.

One choline containing product that has been used successfully in pets is CholodinR. Cholodin contains choline, phosphatidylcholine, DL-methionine, and vitamins and minerals. Choline provides methyl groups used by the body in a number of biological reactions and acts as a precursor of acetylcholine. Phosphatidylcholine (lecithin) in part of the plasma membrane of mammalian cells and also provides additional choline for acetylcholine synthesis. Methinonine and inositol also are involved in neurotransmitter metabolism.

Due to its ability to interact with cells of the nervous system, Cholodin is also recommended for pets with epilepsy. Studies have shown decreased seizure frequency in pets supplemented with products containing increased levels of choline and phosphatidylcholine. Cholodin, given at 1-2 pills daily for a small dog or cat, and 2-4 pills given daily for a large dog, and other choline-containing products can be tried to determine effectiveness under your veterinarian's supervision. Do not stop anti-epileptic drugs without your veterinarian's permission.

Lecithin is believed to be generally safe. However, some people taking high dosages (several grams daily) experience minor but annoying side effects, such as abdominal discomfort, diarrhea, and nausea. Maximum safe dosages for young children, pregnant or nursing women, or those with severe liver or kidney disease have not been determined; the same precautions are probably warranted in pets.
