Hi! Just want to confirm if is it okay for my pup to be given a 5in1 vaccine for the third time? I was under the impression that 5in1 should be given twice then it should be 6 or 7in1 the third time. He mentioned that it is 5in1 booster, Is it different? Thank you

I would consult your veterinarian for the best choice for your dog given his age and lifestyle. We may give a 5 in 1 vaccine more than twice depending on the dog's age at initial vaccination, the labeling of the vaccine, and the vaccine manufacturer's specifications, as well as you dog's lifestyle. In some cases, the vaccines may be split into separate vaccinations (i.e. a Leptosporosis vaccine may be added to the Distemper-Parvo combination or may be given separately in a different injection). Discuss your concerns with your dog's vet as they may have reasons for the schedule they are using.
