I am the owner of an adorable pug who's name is Alfie. His owners did not want him as he was not show dog standard, his legs are a couple of inches longer than should be and he had a double set of teeth and only one testicle (the other was located in his stomach.) The previous owner had not socialized Alfie, he loved other dogs but was very wary of people. He was 9 months old when I got him and he is now 2 years. He has done very well with his training, walks to heel, sits and lays when told but there is one problem that I am finding difficult and need someone to point me in the right direction to correct the problem. If a pedestrian without a dog is approaching Alfie stops in his tracks and waits until they are passing to try and catch hold of a trouser leg. His intention is not to bite as he does this with any male visitor who enters the house, dragging and shaking the trouser leg. I have read somewhere to squirt water on him whenever he does this, I'm not sure if this wouldn't excite him more thinking it was a game, can anyone please help??
