I have a 1 year old black lab/blue heeler mix that I adopted. I was told at the time of the adoption that they didn't know if she was spayed or had her shots yet and there is no way to track a vet for records or anything. Is getting vaccinated twice harmful?

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! In this case with no known history, it's better to be safe and protect her. Your veterinarian can discuss what vaccines are indicated in your area. They can also advise you on flea/tick and heartworm prevention. Good luck with Chloe
