If you cut it yourself, you should prepare a set of repair tools, such as direct cutting, bending cutting, needle comb, wooden comb, electric push, iodophor, cotton swab, and add a toothed knife if you need to thin it.
If you go to a pet shop for pruning, you should pay attention to bring your own shower gel and towel. The pool, bath utensils and towels in pet shops are all public, and skin diseases may be infected if disinfection is not complete. So be sure to bring your own items that may be used to reduce the chance of infection!
