This is so important. Get him used to grooming at home as well. Just a few minutes a day on the grooming table will work wonders. It will also make you feel more comfortable about grooming yourself, which will be necessary in between trips to the professional. Your dog may be perfectly accepting of the professional groomer, however, if you are anywhere near as nervous as I was, your pup will detect that and respond differently than with the calm and cool pro.while i didnt bath milo every week at that age. i did groom him just about every week. we may not doing anything major, its primarily for him to get used to grooming. i did trim down all his puppy hair at 10 weeks since he was a summer puppy and i cant keep on top of the long puppy hair. i must have bath him every 2 weeks then. on top of that, desensitize your puppy to ear cleaning and nail clipping. i was reading a ton here before i got milo and i am glad to say, he does very well with grooming. i used to dremel his nails and he didnt like it that very much, so now i just clip it with a clipper and he is great.
