Brushing the Chow Chow's coat will need to happen 2-3 times per week for most of the year, and daily during the spring and fall shedding seasons.
The best brush for Chow Chow dogs is a 2-in-1 brush: the pin side of the brush is good for removing dead hairs, and the bristle side smooths the coat nicely. A greyhound comb, used for combing longer furnishings and helping get out tangles, will be good to have on hand as well.
Prior to your Chow Chow brush, spray the coat with water mist from a spray bottle (with some de-tangling solution mixed in). Then starting at the shoulders, go through the coat section by section with the pin brush, moving in the direction of hair growth; comb the furnishings; then repeat the brushing with the bristle side to shape and neaten the coat. If you encounter a tangle or mat along the way, first try working it out with your fingers, then continue working through it with the end teeth of the comb if needed.
