DHLPP is required as a puppy series beginning at 6-8 weeks old, boosted twice at 3-week intervals and again a year later. Like rabies, after the first year, the distemper/parvo combination vaccine can be given every three years.
Leptospirosis (the “L” in some Distemper combination vaccines) should be included in the annual combination vaccine due to recent increases in Leptospirosis cases. Leptospirosis needs to be boosted annually. This is important because Leptospirosis can be deadly to dogs and is transferable to humans!
Why? Vaccine protection against highly contagious and potentially deadly viruses and bacteria will mean less risk of dogs getting sick. If all dogs that are playing together are current on their vaccines, then you can be assured that your puppy will be playing with fully vaccinated friends.
