Fur brush, dog comb, cat comb, dog brush, cat brush or carder, dear child has many names.
The cardan from #1 All Systems has an extra long handle and longer pin that goes all the way through the fur even on those animals with really dense fur.
This carder cleans the coat safely by removing dead undercoat without damaging it. Soft and flexible enough for the most sensitive coats.
The cardan fits both dogs and cats equally well.
