Well I bought one for my yappy poodle. She is VERY verbal about any little thing, but especially if she sees something irritating, like a leaf fall, a bug walk by, the clouds moving in the sky, a song she doesn't like playing on the radio . . . you get the picture. I tried it on her today while there was a worker in the back yard of our CYV. Usually, I have to put her in a back bedroom with the televison on because she goes beserk when workers are in the yard.
Today, with the Thundershirt on, she watched him out of the slider window for a while (no barking, well, one bark) and then took a nap on the bed while he proceeded to make all kinds of noise.
The shirt works.
Who knew?
Reminds me of that movie I recommended you all to see, "Temple Grandin".
