Pet's info: Dog | Shih Tzu | Male | unneutered | 1 month and 28 days old | 2 lbs

I have an 8 week old shih tzu with first vaccines at 6 weeks and a 3 years old vaccinated shih tzu. I just want make sure that it is safe for my dog and puppy to play and interact together. Are there risks of catching any viruses from each other because the little one is not fully vaccinated.

Hello. There is very little danger of your new puppy contracting anything from the older one ( & visa versa ). The problem is with what is infectious & dangerous out in the world, so keep your little one at home, no parks, playdates or trips to the pet superstores until he has received the full series of vaccinations around 4 months of age. Thanks for using Petco Pet Education Center, formerly Petcoach.
