Here's a little history....Oscar is 4 months old and weighs 2.2lbs. He's not a great eater so I've had a heck of a time finding dog food he likes. He eats Stella & Chewy freeze dried beef dinner and blue buffalo puppy kibble. Since I've had him he has had giardia, hookworms, a urinary tract infection, and now coccidia. He is currently being treated for the UTI with amoxicillan but it is day 4 of the antibiotics & he is still peeing frequently & with blood. The coccidia, I just found out about from his fecal sample. Since he is so small, the vet doesn't want to treat him for it until he finishes his meds for the UTI. Could these things be caused from him eating poop? I've caught him eating or playing (I'm not sure) with his poop a few times. I've definitely seen him eating wild rabbit poop. I don't even care that this is a disgusting an embarrassing habit, I just want it to stop and for him to be healthy. Also, does anyone know of a type of probiotic supplement I could give him?
