Poor Kain! It's common for dogs to be a bit more lethargic than usual for a day or two after a vaccination - he might also act sore in the area where the shot was given. Sometimes loose stool can happen also. These are usually normal side effects that should resolve within 24-48 hours. If the problem continues longer than that, or if he has any vomiting, difficulty breathing, facial swelling, or if the diarrhea is bloody, I would recommend taking him back to your vet for a recheck visit since these can be signs of a more serious vaccine reaction.
