I ordered this inflatable collar to keep my dachsund mix from squeezing through our fence! She isn't necessarily happy about wearing it, but isn't unhappy either. It's comfortable, fits securely, especially when attached to her collar. I even leave it on her for several hours at a time so that she can come and go through the door whenever she wants. She naps in it comfortably. I'd definitely recommend this product and buy it again.
