My 3 year old lab starting having seizures in March, 2018 (age 2.75). He was put on Keppra, 750 mg., bid after his second seizure. Blood work was negative for “poisoning”. We have both Sago Palm and Lantana. He had normal liver function on blood work. He was sent to a neurology Vet who doubled the Keppra dose to 3000 mg. q.d. About 6 wks later, he started vomiting and had bloody diarrhea and would not eat anything. He had an abdominal X-ray which showed acute gastritis. He was hospitalized for two days-got IV Flagyl and Amoxicillin. He almost died but recovered fully. Three Vets said this could be due to toxicity from the high dose Keppra, but the neurologist states it is not even remotely possible. We cut back the Keppra to 750 bid. He has had no other Gi symptoms but continues seizures about every three weeks. The neuro Vet prescribed phenobarbital, but we don’t want to give it due to possible liver damage. Is it possible this could be the lantana? Would poisoning from this show up on blood work? They assured me this would not be poisoning from Sago, but we didn’t discuss Lantana. He loves to eat nut grass around the plants as does our other lab. She has never been sick. I’ll mention that his brother (litter mate) had PRAA at birth-not a really healthy litter. Thank you so much for any advice you can give me. I plan to take him to TAMU for a work-up when we can afford it.
