I have 2 dogs with long hair that mats very easy so grooming them is a huge chore and very uncomfortable for them. Even after reading the positive reviews on this, I was sceptical but decided to give it a try. What a pleasant surprise - it does work! As other reviewers stated, it can be used on dry fur. I just sprayed it on, waited a few minutes for it to soak in, and then combed. The mats came out in less than 1/2 the time and without all the usual pulling. My dogs even seem to be getting less fearful about being groomed. Good job Tropiclean.
