The Pacific Northwest Dog Owner's Guide to Year-Round Grooming

Dogs shed the most in spring (March through May) and again in fall (September through November), according to the American Kennel Club. In the Pacific Northwest, where it rains 150+ days per year, grooming needs are more intense than in drier climates. Your dog needs different care in each season, and a generic grooming schedule won't account for PNW mud, dampness, and extended rainy periods.

Here's a season-by-season grooming calendar built specifically for Washington and Oregon dog owners.

Spring (March–May): The Great Shed

Spring is peak shedding season for dogs. Double-coated breeds (Golden Retrievers, Huskies, Labs, German Shepherds, Border Collies) "blow their coat" over a 2 to 4 week period, shedding their dense winter undercoat. According to the AKC, this seasonal shed is triggered by increasing daylight hours, not temperature.

What to do:

• Brush daily during the 2–4 week blowout period. A coat rake or undercoat deshedding tool is your best friend.
• Book a professional deshedding treatment. This is the single most impactful grooming appointment of the year. Groomers use high-velocity dryers and specialized tools to remove loose undercoat that brushing alone can't reach.
• Don't shave your double-coated dog. This is the most common mistake PNW dog owners make. Shaving damages the coat texture permanently and removes your dog's natural insulation, which actually keeps them cooler in summer, not hotter.

PNW twist: Spring rain + blown coat = mud caking into loose undercoat = matting. Brush damp fur before it dries. Wet mats set as they dry, and then you're paying a de-matting surcharge.

Spring Grooming Frequency

Summer (June–August): The Easy Season

Summer is the lowest-maintenance grooming season in the PNW. Temperatures reach the 70s to 80s in Seattle and Portland, often stretching into September. But summer comes with its own grooming hazards.

What to do:

• Check paw pads after hikes. Summer trails mean dry dirt, gravel, and foxtails. Foxtails are barbed grass seeds that burrow into paws, ears, and skin. They're a real hazard on PNW trails from August onward and sometimes require vet removal.
• Watch for ticks and fleas. Grooming appointments double as early detection. Your groomer will spot parasites you might miss at home.
• Maintain your regular schedule. Don't skip summer grooms just because the weather is nice. This is actually the best time to establish a consistent routine before the fall rains return.
• Keep your dog hydrated. PNW dogs aren't always acclimated to heat. Schedule outdoor grooming appointments (mobile or otherwise) for mornings, not mid-afternoon.

PNW bonus: This is a great time of year for outdoor adventures followed by a fresh groom. Many groomers in the San Juan Islands and along the Oregon coast see a spike in bookings from vacationing dog families.

Fall (September–November): Prep for the Wet

Fall is the second shedding season for double-coated breeds. Dogs shed their lighter summer coat and grow a thicker winter undercoat, triggered by decreasing daylight. In the PNW, rains return by mid-October, making this your last window to get ahead of mud season.

What to do:

• Schedule a full groom in late September or early October. Think of it as winterizing your dog. Get the coat trimmed, deshedded, and in good shape before six months of constant dampness.
• Start ear care routines. Floppy-eared breeds (Goldens, Doodles, Spaniels) are prone to ear infections in wet weather. Moisture gets trapped under those ears. Ask your groomer to clean ears at every appointment through spring.
• Trim paw pad fur. Long fur between the pads acts like a wick, pulling mud and water up into the foot. Short pad fur = less mud tracked into the house and fewer irritation issues.

Winter (November–February): The Long Wet

Winter in the PNW means 4 to 5 months of persistent rain, temperatures in the 40s, and mud everywhere. Your dog's grooming needs are at their peak. Damp, matted coats trap bacteria and cause hot spots, making regular grooming more critical than in any other season.

What to do:

• Don't skip grooms. Damp, matted fur harbors bacteria and causes hot spots. Maintain your regular 4–8 week schedule even though your dog is just going to get muddy again tomorrow.
• Ask for a winter cut. A slightly shorter belly and leg trim reduces mud collection without sacrificing warmth. Your groomer knows the sweet spot.
• Dry your dog thoroughly. After every wet walk, towel-dry or use a low-heat blow dryer. Never let a dog air-dry in cold weather. It's uncomfortable and promotes that persistent wet dog smell (which is actually caused by microorganisms on the skin becoming more active when wet).
• Moisturize. Here's the counterintuitive PNW problem: even though it's wet outside, central heating dries indoor air. Your dog's skin can get dry and flaky even during the rainy season. Ask your groomer about moisturizing shampoos or conditioner treatments.

Winter Paw Protocol

1. Before walks: Apply paw balm (Musher's Secret or similar) to protect pads
2. After walks: Rinse paws with warm water, dry thoroughly between toes
3. Weekly: Check for cracks, irritation, or debris lodged between pads
4. Monthly: Have your groomer trim pad fur and nails

FAQ

When do dogs shed the most? Dogs shed the most in spring (March through May) and fall (September through November). This seasonal shedding is triggered by changes in daylight hours, not temperature, according to the AKC. Double-coated breeds like Huskies, Golden Retrievers, and German Shepherds blow their undercoat over a 2 to 4 week period during these transitions. In the PNW, spring shedding is typically more intense due to longer, wetter winters producing thicker undercoats.

How do I manage dog shedding season? Brush daily during peak shedding (2 to 4 weeks in spring, 1 to 2 weeks in fall) and book a professional de-shedding treatment early in the season. Professional high-velocity dryers remove loose undercoat that brushing alone cannot reach. Never shave a double-coated breed; the AKC warns that shaving can permanently damage the coat texture and removes the dog's natural insulation system.

Should I groom my dog differently in winter vs. summer? Yes. Winter grooming in the PNW focuses on keeping your dog dry, preventing mats from moisture, and maintaining skin health despite dry indoor air. Summer grooming is about paw care after hikes, tick checks, and maintaining a consistent schedule. For detailed winter tips, see our winter grooming guide.

How often should I take my dog to the groomer? It depends on coat type. Curly and long-haired breeds need grooming every 4 to 6 weeks. Double-coated breeds can go 6 to 8 weeks, with more frequent visits during shedding season. Short-coated breeds can go 8 to 12 weeks. Read our full grooming frequency guide for a breakdown by breed.
