How to groom a large dog?

As someone who’s spent over a decade working in pet grooming, I can’t tell you how many times I’ve had a first-time large-dog owner call me panicking about their 70-pound Great Dane’s matted back, or their 90-pound German Shepherd hiding under the couch because a brush scared him too much. Large dog grooming isn’t just a scaled-up version of what you do for a Chihuahua or a French Bulldog—it’s a whole different beast, pun totally intended. It requires patience, the right tools, and a routine that works for both you and your big, furry friend. And as a professional pet grooming supplier, I’ve seen first-hand when owners cut corners (or use the wrong gear) and end up with frustrated dogs, even more mats, or worse—skin irritation. Pet Grooming

First, let’s get one thing straight: large dogs aren’t just small dogs in bigger bodies. They have unique grooming needs that many new owners miss. For example, a Golden Retriever’s double coat traps way more undercoat than a Shih Tzu’s single coat, and a Mastiff’s loose skin around the neck and chest can hide dirt and moisture that leads to infections if you don’t clean those areas properly. Also, large dogs need more physical space when you’re grooming—trying to fit a 100-pound Rottweiler onto a tiny bathroom counter is a recipe for a trip to the vet for a scraped knee (for you) or a spooked dog. That’s why I always recommend setting up a dedicated grooming space: a non-slip, elevated table (yes, even for home grooming) is a game-changer, or a large, non-slip area on the floor like a rubber mat to keep your dog from sliding mid-brush.

Now, let’s break this down step by step, from pre-grooming prep to post-grooming touch-ups, with tips I’ve learned from both my in-salon work and supplying gear to home groomers across the country.

Start with the Right Tools (No, Not a Human Hairbrush)

This is where I see the most mistakes. Many owners grab whatever brush they have in their bathroom drawer and then wonder why their dog is squirming. For large dogs, you need tools designed for their coat type. First, figure out your dog’s coat: is it double-coated (like Huskies, German Shepherds, Golden Retrievers), single-coated (like Poodles, Boxers), or long with thick hair (like Newfoundlands, Saint Bernards)?

For double-coated large dogs, a slicker brush with long, flexible pins is non-negotiable. The pins need to be long enough to reach through the topcoat and get to the undercoat, which is where mats form. A undercoat rake is also essential—this tool looks like a small metal comb with two rows of teeth, and it’s made to pull out loose undercoat without scratching the skin. I can’t tell you how many times I’ve seen owners use a regular comb on a double-coated dog and just spread the loose hair around instead of removing it.

For single-coated large dogs (like Labrador Retrievers, Dobermans), a rubber grooming brush or a curry brush works best. These are gentle enough for daily use and help remove loose hair without irritating their sensitive skin. For long-haired large dogs (like Shih Tzus, though wait—no, long-haired large examples: Afghan Hounds, Komondors), a pin brush with rounded tips is key to avoiding snags, plus a metal dematting tool for any stubborn mats.

And don’t forget essentials that aren’t brushes: a pair of rounded-tip scissors (never sharp, pointy scissors—you’ll accidentally cut your dog’s skin), ear cleaner formulated for dogs (human ear cleaner can damage their inner ear), nail clippers designed for large dogs (small clippers will crimp the nail and cause pain), and a dog-specific shampoo. Human shampoo has a different pH balance than a dog’s skin, so using it can lead to dryness, itching, or even infection. As a grooming supplier, we stock all these tools for exactly this reason—owners don’t have to guess what works.

Prep Before You Even Grab Water: Tackle Mats First

Bathing a dog with a mat is the worst idea. The water makes the mat tighter, and once it’s wet, it’s almost impossible to remove without cutting the dog’s hair (which is stressful for both of you and can lead to uneven coats). So, before you touch a hose, go through your dog’s coat section by section.

Start at the neck, where mats are common because dogs rub against furniture, then move down the back, chest, legs, and tail. If you find a small mat, use your fingers to gently pull it apart first—never yank, that hurts. If your fingers can’t get through, use a dematting tool slowly, holding the hair near the skin to avoid pressure. For larger mats, you might have to use the slicker brush on the edges, working your way toward the center. If you’re really stuck, it’s better to bring your dog to a professional groomer than risk hurting them. Pro tip: If you groom your large dog at home, do this mat work in 10-minute chunks so neither of you gets frustrated. Large dogs have short attention spans too!

Bathing: Make It Calm, Not a Water Fight

Bathing a 80-pound dog isn’t like bathing a cat—it requires a plan. First, gather all your supplies before you start: shampoo, a large cup for rinsing, towels (lots of them—large dogs drink more water, splash more, and dry slower), and a non-slip mat. Many owners try to bathe their large dog in a regular bathtub, but that can be too small and slippery. A backyard kiddie pool works great, or even a large utility sink if your dog is on the smaller end of large (like a Standard Poodle, which is around 60 pounds).

When it comes to water temperature, it should be lukewarm—too hot will burn their skin, too cold will make them shiver and try to escape. Start by wetting their body, not their head, to keep them calm. When you wash their head, use a damp cloth instead of pouring water over their face—this avoids getting water in their ears (which causes infections) and in their eyes (which irritates them). For shampoo, lather it first in your hands, then apply it to their coat, focusing on the areas that get dirtiest: paws, belly, and under the tail. Rinse thoroughly—leftover shampoo will make their coat itchy and lead to flaky skin.

After bathing, don’t towel them off roughly—pat gently, especially around the face, ears, and tail. If your large dog has a thick double coat, a quick blow dry on low heat (keep it moving so you don’t burn their skin) will cut down on drying time and prevent mildew in their coat. I always tell owners: never skip the blow dry for double-coated dogs. We had a client last year whose Great Dane got a yeast infection because she skipped drying his undercoat after baths—so trust me, this step matters.

Nail Trims and Ear Cleaning: The “Invisible” Parts of Grooming

Large dog owners often forget about nail care, but overgrown nails can cause pain, difficulty walking, and even joint issues. For large dogs, you need clippers that can handle their thick, strong nails—guillotine clippers work for smaller large dogs (like Boxers), but for Great Danes or Mastiffs, a rotary nail grinder is better, because it’s gentler and less likely to split the nail (which bleeds a lot and hurts).

If you’re nervous about trimming nails, start small: let your dog sniff the clipper, then touch their paw, then gently hold a nail. Reward them with treats every step of the way. If you hit the quick (the pink part of the nail that has blood vessels), don’t panic—use styptic powder to stop the bleeding, which I keep in every grooming kit for this exact reason.

Ear cleaning is another big one for large dogs, especially breeds with floppy ears (like Cocker Spaniels, Basset Hounds). Floppy ears trap moisture and dirt, leading to ear infections. To clean their ears, apply a small amount of dog ear cleaner to a cotton ball (never insert the cotton into the ear canal—just wipe the outer part of the ear and the inside flap). If you notice redness, a bad smell, or your dog shaking their head a lot, stop and see a vet—those are signs of an infection, not just dirt.

Routine Is Key: How Often to Groom a Large Dog

This is something owners ask me all the time, and the answer depends on their dog’s coat. Double-coated large dogs (Huskies, German Shepherds) blow their undercoat twice a year, so they need weekly brushing during those times to prevent mats and loose hair all over your house. Single-coated large dogs (Labradors, Boxers) only need brushing once every two weeks, plus a bath once a month. Long-coated large dogs (Afghan Hounds, Komondors) need daily brushing to keep their coats from matting, and professional grooming every 6 weeks.

I always recommend combining home grooming with professional visits. A professional groomer can do deep cleaning, nail trims, and check for skin issues you might miss at home. As a pet grooming supplier, I work with both individual owners and grooming salons to provide tools that make both home and professional grooming easier.

Common Mistakes to Avoid

Let’s wrap up with the mistakes I see so often that lead to frustrated owners and unhappy dogs:

  1. Using small tools: A tiny brush won’t work for a large dog, and it will take twice as long, leading to your dog being over it.
  2. Skipping the quick check: Mats under the arms, behind the ears, and on the belly are easy to miss—always check those areas.
  3. Rushing: Grooming a large dog takes time. If you’re in a hurry, you’ll cut corners, get frustrated, and your dog will associate grooming with stress.
  4. Using human products: We touched on this, but it bears repeating—human shampoo, lotion, or even toothpaste (never use human toothpaste for dogs!) can cause serious skin or digestive issues.

At the end of the day, large dog grooming is about more than just making your dog look good—it’s about keeping them healthy. A regular grooming routine helps you spot lumps, bumps, skin irritation, or even ear infections before they become serious problems. As someone who’s spent years helping groomers and owners care for big, furry dogs, I know that the right tools and a little patience go a long way.
