Here are some suggestions for choosing dog brushes for dense coats.
A dog slicker brush is designed for long haired dogs such as Golden Retrievers, Great Pyrenees, Shih-Tzu, Yorkies, Bichon Frise and Cocker Spaniels. A slicker brush is made up of wires in a rubber base that has been bent at an angle on the ends of the pin that catch the hair.
Use a smaller slicker brush for around face, legs, feet and tail. Use a larger slicker brush for the rest of the body. Start around the back close to the tail. You must brush to the skin to get rid of dead skin cells and stimulate circulation. Brush with the grain of the hair and be gentle. If you cannot get to the skin with a slicker brush you have matts and need a dematting rake. Brush small portions of hair working your way from the tail to the head. Brush small patches in an upwards motion powered by the wrist much like you would use a brush in your own hair. After brushing the body, then do the legs, feet and face. Be gentle around the face area as it should not take much brushing. Clean the brushes with a metal dog comb.
A dematting rake is a small comb like grooming tool that has only a few long very sharp teeth. With gentle motions, being careful not to go down to the skin, you can cut through matts without hurting the dog.
Dogs that have dense coats and undercoats may need an under coat rake that can thin out the thick undercoat some breeds get during cooler weather. Again be careful not to go to the skin so as not to scratch. Pull with the grain of the hair. Cleaning can be done by hand as the teeth are spaces farther apart. The Furminator is a popular undercoat rake.
Every other day is how often you should brush out a breed with a dense coat. Regular brushing will keep your dog clean and keep the matts and tangles under control. All dogs need regular brushing but dense coat breeds need a little extra TLC to keep them looking good.
