My new puppy walked in a public dog area. Should I worry about Parvo?

Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! I understand your concern. However, the likelihood of Luna developing parvovirus just from being walked in a heavily trafficked area is low unless she directly had contact with feces from an infected dog. I would not be too concerned at this time. Just work with your primary care veterinarian in starting her on a vaccination protocol and avoid contact with other dogs with an unknown vaccination status until she is fully vaccinated. I will tell you what to look for in terms of parvovirus symptoms though again it is unlikely that she has parvovirus. Symptoms usually include lethargy, vomiting and/or diarrhea. Contact your veterinarian to get her set up to start a vaccination program soon. I think she will be fine. Nothing like getting a new pup! I bet she is adorable! Good luck!
