Remi has gotten better with greet and passing dogs on the street, his only problem is with dogs that bark behind a fence, or if they stop walking. Since he's been getting better I've started walking with my roommate, we try to take both our dogs. Chance and Remi walk fine together until they see another dog. Chance will start to whine and then Remi will freak out. Chance is normally okay with them as long as they keep their distance, but once we walk them together they both become very reactive. If Chance doesn't start it than Remi does. I would love for them to be able to walk together, since we do a lot of hiking, and Chance loves it. My roommate won't walk him by herself, the only time I can get her to walk is at the same time I exercise Remi. I don't think its fair to leave one home. My question is, is there a way to train them to walk peacefully together? And set each other off when they see another dog?
