I just feel that I have to protect them is all . . .you know when you walk into a vet office there are all kinds of dogs big and small on leashes and I just don't feel comfortable walking them in with their harness on . . .and most of the larger dog people let their dogs go to the end of their leash to smell other dogs and that makes me uncomfortable . . .the last time I was holding one of them while waiting our turn, a larger dog was allowed to get close enough to sniff . . .my immediate reaction was to stand up . . .the woman said "oh he's friendly" yah until he makes one of my dogs his snack . ..
