we have a Pug (Henry) who is 13/14 yrs old. He was just fine the other day. Healthy appetite, and bodily functions. Today he’s seems sick. He hasn’t moved all day or eaten anything. He’s drinking water but all he’s doing is sleeping and snoring loudly. I called the vet but he wasn’t able to be seen, but he told me Pugs can go quickly without warning. I don’t think he got into the kids Halloween candy, but who knows for sure. He’s breathing is eradicate almost laboring to an extent. My kids and wife are very attached to him. Any ideas what’s wrong with him?
