Plan on brushing, checking nails and ears, and managing hair in your home every single week. Giant breeds do not need fussy daily styling, but their size turns every basic task into a bigger job — more coat to move through, more nail to trim, more dryer time, and more hair on your floors. Build low-stress handling early, keep the routine predictable, and you may help support healthy skin and a coat you can actually live with. Individual dogs vary, so let your dog’s coat and skin tell you when to adjust.
In my exam room last fall a family brought in their 7-month-old Great Dane, already 105 pounds and still growing, with tumbleweeds of short hair rolling across their hardwood three weeks in to living together. They had expected a wash-and-go dog because his coat was short. They were sweeping daily, wiping drool off the walls, and dreading nail trims because he pulled his huge paws away. We mapped a baseline together: twice-weekly rubber curry, weekly ear and nail check, bath only when dirty or smelly, and a vacuum plan. Once they saw it as load management, not beauty work, they relaxed.
Puppyhood: Build the Handling Baseline First
Teach the positions before you need them. Practice stand-for-brushing, chin rest for ears, and paw handling for nails in short sessions with treats. Keep baths calm and infrequent unless your puppy gets muddy.
For most giant puppies, do this weekly: brush 5 to 10 minutes, lift ears and look for redness or odor, wipe facial folds or jowls if you have a drooly breed, and touch each paw. Trim just the sharp tip of one or two nails at a time while you are learning. The American Kennel Club notes that over-bathing can strip coat oils, so bathing on an as-needed schedule may help support normal skin barrier function for many dogs.
Short, positive reps now prevent wrestling a 140-pound adult later.

Adulthood: The Weekly Load by Coat Type
This is where coat type decides your calendar. Short, dense coats like Mastiffs, Danes, and Rottweilers shed steadily all year and blow more in spring and fall. Long or double coats like Newfoundlands, Leonbergers, and Great Pyrenees mat at friction points and need line-brushing to the skin.
Brush short giants 1 to 2 times per week with a rubber curry or soft bristle brush. Brush heavy-coated giants 2 to 4 times per week with an undercoat rake and slicker, then comb behind ears, armpits, and pants. Bathe when dirty, usually every 4 to 8 weeks, and rinse drool and feet as needed. Plan nail trims every 3 to 4 weeks and ear checks weekly, especially for drop-eared breeds.
One owner I counseled tried to out-bathe the smell on her 3-year-old, 130-pound Newfoundland mix — full bath every weekend, plus daily top-brushing that never reached the undercoat. By day 10 after each bath she was back to odor and damp-feeling fur, and by week six she found tight mats behind the elbows. We flipped it: fewer baths, deeper twice-weekly brushing in layers, thorough drying after swimming, and a sanitary trim around feet and rear. The tradeoff was time per session, about 25 minutes instead of 10, but the coat stayed drier, looser, and easier to live with.
Drying matters as much as washing. The VCA Hospitals grooming guidance emphasizes thorough brushing and regular coat care to reduce mats and skin irritation, which is exactly where giant owners fall behind because there is simply more surface area. If you bathe at home, use lukewarm water, a dog-formulated shampoo, full rinse, and complete dry to the skin.
If shedding overwhelms you, compare expectations before you commit to a second giant — our Dog Breed Care Guide: How Care Needs Actually Vary by Breed walks through how coat, size, and lifestyle interact, and Best Hypoallergenic Dog Breeds for Allergy Sufferers explains why no breed is truly non-shedding.
The Rest of the Body: Nails, Ears, Teeth, and Drool
Coat is only half the load. Giant nails grow thick and fast, and long nails change stance and traction on slick floors. Check weekly, trim or grind regularly, and ask your vet team for a demo if you are nervous about the quick. Clean ears only as needed with a vet-approved cleaner — routine deep cleaning is not preventive.
Wipe jowls daily for breeds like Saint Bernards and Bullmastiffs, and wash food and water bowls often. Brush teeth or use accepted dental products as your vet advises, and fold a quick skin check into brushing: redness, flakes, hot spots under dense fur, or lumps you cannot see under all that coat. The ASPCA outlines these same basics — brushing, bathing, nail care, and ear checks — as the core home routine between professional visits.
Expect professional help sometimes. A groomer with a high-velocity dryer and walk-in tub can save your back and your bathroom.
Senior Years: Less Stamina, Same Coat
Do not skip grooming when your giant slows down. Older dogs lie more, which mats the hips and elbows, and they tolerate standing for shorter periods.
I think of an 8-year-old, 148-pound Saint Bernard I saw for a routine visit whose owner worried his rear coat had turned coarse and thin over two months. He could no longer stand for a full brush-out, so she had stopped trying. We broke care into two 10-minute chair-side sessions per week — one side at a time while he lay on his bed — plus monthly nail checks because he was wearing his nails unevenly. That smaller, steadier plan kept his skin visible and his feet comfortable without exhausting him.
For seniors, brush on a soft bed, support arthritic limbs instead of pulling them, keep paw fur trimmed for grip, and report new odor, itch, sores that do not heal, or sudden shedding changes to your vet. Comfort is the goal now.
My Take: Budget Time, Not Just Money
If I had to give one expectation-first rule for giant grooming, it is this: budget 30 to 60 minutes a week for brushing plus nails and ears, and a half-day a few times a year for a deep bath, dry, and de-shed. The strongest counterargument I hear is to just pay a groomer monthly and skip home care, and for some families that works. I still land on home baseline first because mats, long nails, and ear infections do not wait for appointments — and a dog that accepts handling at home is safer everywhere, including the vet clinic.
