Emergency Vet Trip this Morning
So I noticed last night that Samson had not drank as much water from his bowl as normal, but dismissed it since we had been at the park earlier and I had brought water with us. He drank plenty then. At about 6 AM he vomited his food from the night before, refused to eat, and vomited several more times to the point of essentially dry heaving (just a small amount of white stuff comes out).
We went promptly to the vet when they opened. I've been through the house and yard and can't find evidence of something he's chewed or eaten that would cause an obstruction. There was a shoe that he had gotten and torn out a small portion of the inner lining, but all but a 1"×1" portion is accounted for (not enough to cause an obstruction). He's 6 months old and still very much a puppy, so it's possible he found something in a kids room and there's no evidence.
The vet did an xray while we were there and didn't find anything other than noting he hadn't pooped in a while. There has been a virus going around, and it starts out as vomiting, then goes to diarrhea. He's spending the day there on an IV to keep him hydrated and they're also doing a barium contrast xray to rule out a blockage. The vet believes it's the virus, but knowing Samson and how he's into everything I'm very concerned it could be an obstruction. Seems the symptoms are similar.
Side note, we came back from vacation Saturday night and picked him up from my parents. I forgot to grab the baby gate that we use to keep him out of the kids' rooms at night. That's a big reason I'm concerned about an obstruction.
