Another first class product supplied by Groomers. Unfortunately the package arrived damaged in transit, a quick call to Groomers and a replacement was delivered the following day. 100% satisfied, excellent customer service. Always a pleasure.

I wish I could show in this text a pair of before and after photos of our once white Bichon Fiize after a walk on a wet and muddy golf course. What a transformation!
