Phew! The vet just called. Nothing on the x-rays. Literally, nothing at all in his digestive tract. The poor little thing really eliminated everything available. His blood work is fine, except for a little low on the protein and potassium, but both can be explained by the vomiting and diarrhea. He is resting and being hydrated, so I’m going to let him stay over night and I’ll get him in the morning after he’s had a bit more time to absorb some water, have food introduced slowly, and hopefully, he’ll be just fine. They think he had an extreme allergic reaction to something he ate (horse poop?) or something he came in contact with at the dog park. I’ll keep an eye on the little fella. I wish I had him here to snuggle with, but I think the responsible thing is to leave him at the vet. The hospitalization fee was for 24 hours, so it will cost the same as if I had to go and get him now. Thanks for the vibes!
