Query: worked well with a lot of patience

We tried a number of brushes and found this one to work the best for matted fur. But it's no miracle brush, you still need a lot of patience to tease out the tangles. Another good alternative is:JW Pet Company GripSoft Dematting Rake Dog BrushHere's what we found best for stubborn tangles:Oster 78005-140 Golden A5 2-Speed ClippersThese clippers come with a blade perfect for tangles:Oster 78919-046 CryogenX Professional Animal Clipper Blade, Size 10
