Quick answer

Wash your dog's winter jacket only when it's visibly dirty or smelly, using a gentle cycle at 30°C and a small amount of mild detergent. Skip fabric softener, air-dry flat, and brush off loose dirt between washes. That routine protects the insulation and water-repellent finish on jackets like the Lämmittävä Midlayer ECO and Expedition II.

Why winter coats need a gentler routine than you think

Insulated dog jackets trap warmth in two ways: the fill and the outer fabric's water-repellent coating. Hot water, harsh detergents, and tumble drying break down both. A coat that once shrugged off sleet can start soaking through after just a few aggressive washes. The fix isn't complicated — it's just a slower, cooler process than you'd use for a human fleece.

What you'll need before you start

Gather a mild liquid detergent (pet-safe or a gentle wool wash), a soft-bristled brush or damp cloth, and a drying rack or towel. Avoid powdered detergent — it can leave residue in the seams. If your jacket has a foil tricot lining, like the Lämmittävä Midlayer ECO, check that the detergent has no bleach or enzymes before you commit.

How often should you actually wash it?

For most dogs, every 4–6 weeks during heavy winter use is plenty. If your dog wears the jacket daily on muddy trails, rinse or spot-clean weekly and do a full wash monthly. Overwashing is the most common mistake — it strips the water-repellent finish faster than dirt ever will.

Step-by-step: cleaning your dog's winter coat

  1. 1. Brush off loose dirt and hair: Before the jacket gets wet, use a soft brush or damp cloth to remove mud, salt, and shedding hair from the outer fabric. Pay attention to the belly panel and leg openings where grit collects. Checkpoint: if the jacket is only dusty, stop here — a brush-off may be all it needs.
  2. 2. Close all fasteners and turn inside out: Zip or clip every closure so straps don't snag, then turn the jacket inside out. This protects the outer water-repellent face and the foil lining from abrasion in the machine. Common mistake: leaving the jacket right-side out, which dulls the outer finish over time.
  3. 3. Wash on a gentle cycle at 30°C: Use a mild liquid detergent — about a tablespoon is enough. Select a delicate or hand-wash cycle with a low spin. Never use fabric softener or bleach; both clog the fabric's breathability and water repellency. Checkpoint: if your machine has no gentle cycle, hand-wash in a sink with cool water instead.
  4. 4. Rinse twice to remove all detergent: Run an extra rinse cycle or rinse by hand until the water runs clear. Detergent residue left in the padding can irritate your dog's skin and reduce the jacket's ability to wick moisture. Common mistake: assuming one rinse is enough — insulated layers hold soap longer than you'd expect.
  5. 5. Air-dry flat, away from direct heat: Lay the jacket flat on a drying rack or a clean towel, reshaping it gently with your hands. Keep it out of direct sunlight and away from radiators. Never tumble dry, even on low — heat can warp the foil lining and shrink the outer shell. Checkpoint: the jacket is dry when the seams and padding feel completely dry to the touch, usually 12–24 hours.
  6. 6. Re-fluff and store loosely: Once dry, shake the jacket gently to redistribute the insulation. Store it on a wide hanger or folded loosely in a dry cupboard — not compressed in a tight bag, which can flatten the fill over summer. Next step: before the next cold snap, check the fit around the chest and legs, since washing can slightly relax the fabric.

Product details that affect how you clean

  • Lämmittävä Midlayer ECO koiran takki: The Lämmittävä Midlayer ECO has a foil tricot lining, the same type used in the Extreme Warmer, and articulated front-leg folds. The foil lining reflects body heat, so wash it gently to avoid cracking or peeling; the leg folds need to stay free of detergent residue so they keep moving with your dog.
  • Expedition II talvitakki: The Expedition II winter coat is designed to stay in place without restricting movement, and the ECO model includes dog-friendly updates. Its minimalist shape means fewer seams to trap dirt, but the fit relies on the fabric holding its structure — so avoid wringing or twisting it dry.
