Many groomers will recommend between ½ to ¾ of an inch, keeping a slightly fuzzy cut. Others suggest 1-2 inches, evenly spread over the dog’s body. Goldendoodles can have one of two coat types, so it’s impossible to give an overall recommendation! There are rules you should follow. Never cut a Goldendoodle's hair too short, as it will interfere with their natural ability to regulate body temperature. Never shave your Goldendoodle bald unless specifically advised by a veterinarian.
