Remove dead hair efficiently: The teeth of the stainless steel brush penetrate the hair to comb your dog or cat's hair. One-touch design, easy to clean brush: The blue button on the handle operates a very simple yet sophisticated mechanism to remove all dead hair and deposits. The retractable bristle design ensures that the grooming brush can be safely and easily stored in your care kit when not in use. Promote blood circulation, making the hair shinier: When you are free, it is time to comb your pet's hair. Not only does it comb our your pet’s dead hair, but it also promotes blood circulation in the epidermis and makes the hair shinier. Note: Long-haired pets need their hair combing once a day. Please be nice and light when combing your pet’s hair. Before combing your pet, make sure that it has no cuts or wounds on its body. Otherwise, it may hurt when combing its hair.
