The shelter thought that he was about two years old. Boomer is very high energy, but the most loving dog I have ever met. He is so grateful for being saved from the shelter the day that he was supposed to be euthanized. He does very well with other dogs, but it does take him some time to warm up to them. Boomer is just learning to walk on a leash, but is completely potty trained. He's very good at letting me know when he needs to go outside. He currently has a backyard, so somebody with a yard would be ideal. If not preferably someone Who plans to exercise him daily. Boomer does not seem to like cats, but has never encountered one face-to-face. He loves to give hugs and kisses, and knows how to sit. We are still working with him or not jumping on people.
