Query: Amazing!!

Our vet recommended this deshedding tool to us. We have 3 dogs: a black lab/golden retriever mix, a purebred golden retriever, and a purebred cocker spaniel and this brush is the best product we have ever used on them. I have never seen so much hair come off of my dogs before. If you have dogs that shed then you absolutely need this brush!
