I can’t bark (get it? Ha hah) enough about this jacket!!! Simply the best and I’ll tell you why-We adopted a (neglected) senior dog with bags of separation anxiety. We’re talking pissing ALLLLLLL over the house (even though he has a doggy door and access to the garden) on the bed, when he was locked out of the bedrooms, on the carpet, when we crated him, all over the crate and himself. Ew, I know. He’d be ripping up anything and everything, he even managed to climb onto a table and eat CHOCOLATE cookies (jerk), and he’d be barking like a bloody lunatic- NOTHING could stop him from barking for 10, 20, sometimes 30 mins straight- when we left and came back. We were one bark away from a refund on this dog UNTIL the thunder shirt jacket!!We got the package, put on the jacket (see the packaging in the background of the picture, yes, we were THAT excited), he instantly mellowed out. We left him at home in his lightweight jacket thinking there’s another puddle of pee for us to clean up... NOPE! He didn’t even bark once!!Best part? He LOVES it! Every time we pick it up he runs up to it and sits like a good boy all excited.We now have our life back, he’s not stressing out, everything is great!
