I just bought Seamus a harness and leash, and my goal is to by this summer be able to take him to my parents' house with me and let him enjoy the backyard... I don't plan on walking him outside much other than the yard, because this is a relatively busy city street. I'm giving it so much time because I do live in the city and he is very sensitive to sounds like sirens, loud cars, etc. He is wearing the harness for the first time now and is very, very grumpy... for how many hours a day and for how long should I do harness without leash before jumping to leash training then braving the outdoors? I am thinking I will get him microchipped before even taking him out as well, just to be on the safe side...
