i think you should get the baby to the groomer as soon as he gets his first two shots. denzel had his first grooming appointment at 12wks and he loves and i mean loves going to the groomer but before he was going to the groomer i introduced him to taking tiny little baths once a week and i did that when he was 10wks old. so i think the earliest the better although denzel hates when i brush his teeth and the groomer said he doing a lot better but once again the early the better hope that helped good luck
