Beckett has had two rounds of shots and is due for his final booster in two weeks. We want to start walking him (he is a pad trained- no outside pottying). Does he need to have all of his shots first to be safe? He's 14weeks. Is this too young to start walking? He seems cooped up and I want to start exposing him to more of the world (and help him burn off some of his energy). Are the other places we can take him? Thanks
