I have 3 dogs and this brush works great on all 3. Two of my dogs have short hair and it is the only brush i have found that takes a significant amount of shedding hair off of them. My 3rd dog is a 100 pond golden retriever mix who is a shedding machine. This brush takes off an enormous amount of hair, just like they show on the commercial. Its a great value at a third of the cost of other de-shedding tools.
