I thought it worked instantly
I have a mix pug, beagle and boston, adopted when he was one year old, he barks all the time, constantly, we slipped the coat on and at first he ran around in circles, rubbed up on the furniture to get rid of it, but within 5 minutes was good, he seemed to stop the barking and I put it on him when we leave, didn't find things chewed on like my grandson's train tracks that he pulled from the container and chewed although he has a chewy bone. I think the more we use this coat the better it will get, I just ordered one for my bulldog, just to have her feel better although she is older and slower, I think it would be a nice comfort to her! I would recommend this coat for dogs with issues. It's well worth it!
