Hey everyone. Me again. I know I have a tons of question but I want the best for my Charlie. I live in a neighbor with a tons of dogs. Next door I have a 5 month dog and Charlie really wants to play with him. Charlie got his second shot at 8 weeks and now I have to wait the 13 of march for the third one. What are the do's and don'ts with other dogs for puppies. Thank you.
