Q. My dog has epilepsy. She is currently on Phenobarbital, potassium bromide, keppra and zonisimide. I've been told that marijuana can help her?

A. Marijuana is potentially lethal for dogs. So far there are no studies either proving efficacy of marijuana for epilepsy in dogs, nor are there any finished studies using marijuana in dogs as a medication. Looking at the medications your dog is getting, it appears that she has severe epilepsy and is possibly at the high end of dosages. If the cause is a brain tumor there is little hope that the seizures can be kept under control in the future, If it is idiopathic epilepsy, it may be possible to keep the seizures in check with these medications. Please do not experiment with marijuana in your dog, as you may endanger his life doing so.

A. Actually there are no therapeutic studies that have proven marijuana to be effective for controlling seizures in dogs. In fact there is a very narrow safety margin and marijuana can be toxic in pets.

A. Marijuana has been proven to be effective for epilepsy patients in human medicine, but no protocol or doses have been established for dogs yet.
