Manufacturer’s product description
The COARO undercoat brush for dogs and cats is a practical and effective grooming tool for the regular coat care of pets with thick undercoats. Especially during seasonal coat changes, the brush proves indispensable for pet owners who value a clean home and a healthy coat for their four-legged friends.
In product testing, the brush impressed with its high effectiveness in removing loose undercoat and its ergonomic soft-grip handle, which makes it comfortable to use. The double-sided stainless steel blades work precisely and gently, preventing skin irritation. In addition to effective undercoat removal, the product also offers excellent user-friendliness and workmanship.
However, easier cleaning would have been desirable for heavily matted hair.
Overall, the COARO brush delivers very positive results and effectively contributes to a shiny, healthy coat and greater well-being for the animal—and thus to more cuddle time without annoying hairs on furniture.
Advantages
- Effectively removes loose undercoat
- Gentle on the animal’s skin

In practical testing, the COARO undercoat brush proves that it largely lives up to the manufacturer’s advertising promises. Its user-friendliness is particularly noteworthy: the brush can be used immediately after unpacking, fits securely in the hand, and glides effortlessly through the coat.
