We are finding these new Mikki brushes fantastic for getting through thick and dense coated dogs like Cockapoos, Poodles and the furnishing on Spaniels and Westies etc. It really cuts down the grooming time. The head is flexible, which is kinder to both your dog and your own hands. When you are brushing through knots, just keep gently stroking the brush through the tangles and you will feel them gradually break up. Don't forget with a firm slicker brush be careful to brush your dog's coat, not their skin. They are a great price too.
