Pet's info: Dog | Boston Terrier | Male | unneutered | 2 months and 7 days old | 4 lbs

I have a 9 week old Boston Terrier pup. He's been doing great since we got him about 10 days ago. A couple of hours he started having diarrhea (currently watery consistency - no blood, no visible mites/worms). He just vomited his food also. Acting fine - a little peeved that we won't let him out of his play pen. What should we do?

As long as Tea is feeling fine I'm not overly concerned. Puppies get into lots of things so a day of vomiting and diarrhea can be ok. I'd cut back his food for today, make sure he has water and let him rest like you are doing. If he's not better in the morning then take him right in for an exam. Since he's so small and young if he doesn't improve quickly then treatment is needed so he doesn't get worse. They'll check a fecal sample for intestinal parasites, give medication for the vomiting and diarrhea, and if they feel it's a serious problem they may also do a blood panel, parvovirus test or X-ray. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Tea.
