Hi! My puppy is 7 weeks old and just won't walk on the leash! She had her first shot but having another in a while - please help !

Of course she won't walk on a leash, she is a baby ! You are going to have to be patient with the little one. What kind of dog is she? Glad you are having her vaccinated.

Google "leash training a puppy ". Lots of tips and videos.
