It’s thought that the most humane way to dock a Cockapoo’s tail is to do it between 3 and 5 days of age. However, during this early stage in puppyhood, general anesthesia is rarely used due to the risks involved. Sometimes even local anesthesia isn’t used on such young puppies and it will therefore be extremely painful for a puppy. If for any medical reasons your adult Cockapoo’s tail needs to be docked, this can be done at any age. Fortunately, anesthesia is commonly used on adult dogs and it will greatly reduce the pain and trauma your dog will experience during the procedure.
