We have Shih Tzu puppies and their hair is a lot of work to keep away the knots. We have to brush their fur everyday. I keep a bottle with 1 tablespoon of conditioner and a cap full of vinegar mixed with water. Shake well, spray on their fur, and brush. It keeps knots out and makes their coat shiny. Keep away from their eyes.
Long and medium haired pets can get tangles in their fur. You can save money on pet products by making your own pet hair detangler. This is a page about homemade pet hair detangler.
