| The normal sides effects of vaccines are sleepiness, muscle soreness, and lethergic for up to 24 hrs. If your pup has vomiting, diarhea, swelling, hives, shock, or anything else that is abnormal then you'll need to tack your pup back to the vet for medical treatment to reverse the vaccine reaction. Vacine reactions usually occur within the first 4 hours after being vaccinated. |
