Ok. Just got back from vet. Good news is they could find nothing wrong. That makes me feel a lot better about taking that long trip. The only thing that doesn't look quite normal is his liver count. But, it hasn't changed since his appointment in August. So, we're just going to be looking closely to make sure if he does change at all, we'll be sure to catch it. Bad news is, it cost $172 to find this out. But, I'd pay that and more to keep him healthy. He just got through eating dinner and I sang him the happy dog song while he had his noserubber on his favorite blanket. Thanks so much for everyone's kind words. They helped a lot. Seems like I worried so much for nothing.
