I took my dog to the vet this morning because he has been having trouble with walking. His balance is really bad and his eyes keep jumping back and forth as tho he is dizzy. He was vomiting on Saturday. I called the emergency animal clinic on sunday and they thought it may be an inner ear infection. Anyway when we got to the vet this morning... she checked his ears and said they were fine but thinks he has a brain tumer (cancer) and there is nothing we can do but treat the symptoms with a steriod to reduce the swelling of the brain.. and some pepsid if he has an upset stomache. I then told her he had eaten chicken poop. She told me she was going to look up something to see if there is a possible parasite that comes from chicken poo that would give the same symptons. I have yet to hear from her. I was wondering if anyone here has ever heard of dog getting sick from eating chicken poop. I know he didn't get very much and that was about a month ago. He's a lab/shepard mix and he's 13 1/2 yrs old.
