We love this tool for faster knot removal without pulling, thanks for the 360-degree rotating teeth. Ideal for all toy, small and medium breed dogs with knot-prone coats. Also doubles as a de-shedding rake for all shedding levels from non-shed (where dead coat gets stuck in the coat, causing knots and mats), to high-shed, thick or dense coats. Makes quick work of removing stuck coat without pulling. Nice wide teeth spacing for faster removal of knots and loose coat. Removes dead, stuck hair from both undercoat and topcoat without damage. Reduces shedding and risk of knots forming. Flexible, spring-loaded teeth ideal for sensitive pets as the teeth adjust to the curves of the dog's body for sensitive skin. Anti-slip, easy-grip handle. Long pin style teeth reach through even dense, thick coats.
