Tucker has always eaten Science Diet food and has been fairly healthy…he does have PRA which is hereditary where he has gone blind. He started vomiting so I took him to his vet and found out he was dehydrated and have high liver count. He’s been there over night two times and the vet has put him on Science Diet LD and Denosyl and another chewable tablet. He eats it fine and has gotten better. The problem i am having is when I take him outside…he finds anything he can to eat. Is he not getting enough to fill his belly from eating this food?
