In an attempt to both save money and be more environmentally friendly I purchased these for my dryer.
Max seems to be doing better with thunderstorms. I still have to be awake with him but at least he has stopped barking continuously and is down to just random barks. During the second storm last night it was enough that I put on his thunder shirt and let him on our bed. I didn't have to be massaging him so I'd say we are seeing progress.
