Hi everyone, I just had a quick question in regards to my Bernese Mountain dog and her undercoat. She is just over a year old making this summer the first one where she is experiencing shedding. I typically use the Oster Combo brush on her coat, which has a side for the top and undercoat, and is a bristle brush. This has been working well but there is still a large amount of hair coming off her every day even though I brush her every day. I recently got the Safari Shed Magic De-Shedding Tool which removed a good amount of hair. I have only used it once and am curious if this product will cause damage to my dog's coat. The website that sells the brush says "the stainless Steel blades GLIDE through the hair as it gently cuts the furry undercoat out of your dog’s coat". I just don't know if this is a brush similar to the furminator where there will be damage to her coat. Any advice is welcome!!
