No he is not neutered. but will be soon. when he jumps he's usally chasing cats or other small animals. I have taken him to agility classes he passed the beginners with flying colors. I was going to sign him up for the intermediate but the place I took him to stopped doing classes. The next neares place I have found is in New York.
I have thought of using the electric fence thing but he doesn't touch the fence when he jumps. I don't know if the anti-jump jarness will work because he'll probaly just chew it off
