Double-Sided Pet Brush: Expertly crafted with electroplated round-ended steel pins on a flexible cushion (one side) and high-quality nylon bristles (the other), this brush works well for all dogs and cats. The nylon bristles hold their shape and tufting pattern, with offset ends for better penetration-removing loose hair, dirt, and impurities while distributing oils for a healthy coat. The steel pins, ideal for undercoats and longer hair, are widely spaced and round-ended, set in a flexible cushion head for comfort while tackling mats, tangles, and loose fur. To use, brush your pet from front to back and top to bottom: start with the neck and shoulders, move to the back, chest, and hindquarters, then finish with limbs and tail.
