Hi. I adopted a lab mix puppy 2months ago from a local shelter. She got her first set of shots but because I had an accident , I wasn't able to follow up on her vaccines . Should I start her parvovirus shots all over or continue with the second round. I am going to give her the shots myself. And doesn't she only need three parvo shots? And how long do I have to wait between each shot ? And once she has all of her parvovirus shots , how long until I can take her to the park?
