Mako (11 wks) had his DHPP and deworming done yesterday. Since then, he doesn't seem to have much of an appetite and I noticed that twice he's gone out to pee and he gets in position and nothing comes out. Both times he's come back in the house and urinated about 10 minutes later. He did a sort of walking dribble of urine on the kitchen floor (he didn't even try to go off and do it descretely), and I've never seen him do that before. Could he be having side effects from the shots? Should I be concerned?

Hey Chey, every puppy will have some kind of side effects from their shots. Some aren't very obvious - like they nap a bit more; some are more obvious, like they develop a bad case of diarrhea. In most<?> cases at least one of the virus' in the mix are live virus' so effectively your vet had caused your pup to catch a minor case of the disease against which the vaccine is aimed with the intent of providing long term protection.

Deworming medication often causes a loss of appetite and lethargy.

These symptoms should clear within 24-48 hours. If not it's time for a vet visit ....
