We love that these are available. My oldest fur baby (13), is totally deaf now and we needed to let people know so they could understand him and treat him with the same love they did before. The collar is tough and hard wearing so when he plays with his sister aged 3 it will last. The bandana is for when we go for a walk. He gets more pats and love from strangers than he used to. All we need now is a collar or bandana that says my brother is deaf or I am with deaf, his sister wants one too.
