I recently moved back home from Oregon to California for winter break, I brought my chin home with me and since I have gotten him here his poop seem to be smaller. He's eating the same as he was a few months ago (Oxbow pellets, mixed greens, fresh water, and only 1 treat a day (raisin, dandelion drop, nuts). I haven't been able to get him to eat hay in almost a year but he's been to the vet and been healthy. His poop has been small for 2 weeks, is he not getting enough nutrients or is there a bigger issue?
