Thanks so much everyone. Last night Mike took Sgt. to the other side of the living room with treats and I was actually able to vacuum the small rug in front of our back door. It took about 12 minutes, but it's a step in the right direction! I honestly feel 1000% times better knowing that it's not just Sgt. that behaves this way! I knew it wasn't...but reassurance is a good thing! Y'all are the best!!
