Hi everyone, this is my first post, i woull like some advise from more experienced guys.
I have 2 year old dog & bitch patterdale terriers. She is soft & well behaved..The dogis also well behaved, likes to run off when he gets the scent of anything, but always comes back after a couple of min. My problem is he sees other dogs as prey, small or big, no barking just stright in with the teeth. I think its just male dogs. I have to sort it before he kills one. Do you think he needs vasectomy????
thanks for any ideas
