Hi my 12 week boston terrier pup is petrified of his harness, I put it on him a week ago and he was'nt bothered about it at all, so i put the lead on and let it drag along behind him, well he totally freaked out... he thought the lead was chasing him and was flying about the house to get away, by the time id caught him he was shacking and very stressed . So now he hates it! whenever i put it on him he wont move he just sits and shacks, he wont even look at me. Ive been trying it on him for short periods but i have him on my knee most of the time trying to calm him down, but im worried by me doing this he'll think there must be something wrong and end up making the problem worse. Any ideas would be grateful guys.
