I have been using this product for years for my deaf dog, and my deaf fosters - it states very clearly the dog is deaf so very useful.
Great product, good quality and very strong for our big deaf dog!
Great product. Excellent quality
Great product as usual I love these products only one my sensitive skinned girl can wear
We have a deaf Great Dane and the fantastic collars from friendly dog makes it so easy for people to notice that he is not being ignorant, but genuinely cannot hear when someone talks to him
