How old is he, and how much does he weigh?
I know for small dogs that they get hypoglycemic very fast. Oreo almost died because i didn't know anything about that.
Someone on these forums suggested Kaopeptate (sp?) for the diarrhea, make sure he's drinking a lot of water. if you do have Nutri-Cal give it to him just to be safe. if you don't honey and sugar is ok.
But if it's something more serious than hypoglycemia ( well i mean that's serious too) it could be maybe:
- Giardia
- Parvo
- Coccydia (sp?)
I don't want to scare you or anything, but you might want to look up the symptoms to thopse and see if they match up with your pup. I'm sure everything will be fine!
Oh and before i forget, Congrats on your new babie
