“Oreo didn’t eat his dinner last night.” That kind of statement is something I would sometimes hear, and I’ve already lost track of how many had come to the clinic with a similar complaint.

In the case of Oreo, he was full of energy when he came to the clinic. He was wagging his tail, and his vaccinations and parasite meds were up to date. Other than his missed meals, he had no other symptoms, and his physical exam revealed nothing significant. Everything checks out – he is apparently healthy. So, what’s the problem with Oreo?
