I use this mostly on my 20 yr old domestic short-hair, Willow. She has really thick grey hair that can become matted in the spring. This works well reducing hairballs and matted clumps of hair.
I have a Great Pyrenees mix and her back end hair and the long hairs on her tail get tangled often. She often comes in the house with twigs, fall leafs, etc caught in her hairs.
I have a lot of babies to groom highly recommend this comb mostly for smaller ones but I still use it for my Aussie to great purchase
They seem to tolerate the comb better than the other one we had as they aren't pulling away from it.
Nice size and seems to be very well made. Time will tell, but so far so good.
