You can use a pin brush and comb your tyke and make your doggie bath whenever needed. Twice a month will be sufficient.

An easy coat to be groomed, though. Brushing your dog weekly is also wise, for it’ll reduce shedding. Monthly baths are more than sufficient for short-coated dogs. 

Better groom your pooch before taking a bath with a quick brush.
