Thanks everyone. Just got back from 2nd vet today. The local one gave him two shots (one was baytril) in the chest and told me to take him to Sweeten creek animal hospital (40 miles away - made it in less than 30 mins!). He said Buddy had moderate to severe respiratory distress.
Dr bolt in arden kept him to sedate him and get a mucus culture, cloacal culture, and bloodwork. He said they'd call after that was over to let me know he's ok, but I'll pick him up later today since nobody is at the vets office at night. Buddy sounded normal by the time we got to Dr Bolts place, but he said that might be due to exitement (not showing signs). But the weight loss is no good.
They spoke up and down about how healthy he looks and how calm he is with everyone. But Buddy wasnt happy with all of it at all.
