I adopted my dog from a shelter for 10 months now. He was an owner surrender because they “couldn’t handle him”. After having him he is (mostly) a well behaved high energy dog with structure. I’ve taught him plenty of tricks, such as sit pretty, stand, and play dead. He used to pull like crazy on the leash and lunge towards squirrels. Now, he walks politely and checks in on me for permission to go sniff. I would be more than happy to teach your dog a new trick or give him plenty of play time!
