Thank you for doing all you are able to do to keep the dog alive. I hope the pills are as cheap for you also, because it would be a shame to end a life for financial reasons

I do know that epilepsy is quite common in GSD's and yes it is genetic...tell her not to breed him! He really shoud be neutered. It's real important when there is a dog that has a genetic disorder not to have it bred. It will just add to the genetically deficient puppies out there who will end up dying young because of their illness, or being placed into a shelter due to lack of finances to keep up on their medical costs. If your roommate has the contact information from the breeder she should call them and let them know. A responsible breeder will steralize the parents to your roomates dog if he/she learns about this. Good luck and keep up the good and kind work of offering to pay for your roomates dog. That is a wonderful deed, and you will be most rewarded by the life and affection of a lovely GSD!
