My puppy had her second set of vaccinations today and she now has diarrhoea. She’s happy in herself and eating and drinking. Is this common after jabs? Could it be stress from the visit to the vet or do I need to take her back? I could tell she really wasn’t happy being there and there was a dog barking non stop in the next room which I think freaked her out a bit. I posted about puppy having diarrhoea a few weeks ago after we brought her home from the breeder. Could this just be her default reaction to anything out of the ordinary?
