Quick Answer: Dog coats are essential protective gear for short-haired breeds (Greyhounds, Whippets, Dobermans), small dogs, seniors, and long-haired breeds prone to matting (Poodles, Goldendoodles). The best coats feature high waterproof ratings (10,000-20,000mm), silk or satin linings to prevent matting, and materials suited to your climate. Top picks include the Non-stop Dogwear Fjord Raincoat 2.0 (upgraded to 20,000mm rating) and Canada Pooch Torrential Tracker. Critical safety note: Always remove coats indoors and during exercise to prevent overheating, which can be life-threatening. Avoid cheap materials like vinyl/PVC and anything without a certified waterproof rating.

Do Dogs Actually Need Coats?
Not all dogs need coats, but many do. A thick-coated dog in cold rain is like someone wearing a wool jumper that gets saturated and ineffective. A short-coated dog is like someone in just a t-shirt during freezing weather—they need immediate protective layering to stay safe and comfortable.
When coats are essential:
- Temperatures below freezing
- Cold, wet, and windy conditions
- Rain, snow, or muddy environments
- For vulnerable breeds (see next section)
When coats are dangerous:
- On thick-coated breeds like Huskies (overheating risk)
- Indoors (must be removed immediately)
- During strenuous exercise
Which Breeds Need Coats Most?
Short-Haired and Thin-Coated Breeds (Thermal Regulation)
- Greyhounds and Whippets - lose body heat rapidly
- Dobermans and Staffordshire Bull Terriers - struggle in cold
- Boxers - need more coverage
- Small breeds - lose heat quickly, bellies close to cold ground
Long-Haired and Curly-Coated Breeds (Coat Health)
- Poodles and Goldendoodles - prone to matting when wet
- Rough Collies - extensive feathering gets saturated easily
- Shih Tzus - high-maintenance coats
Important Exception
Never coat thick-coated breeds like Huskies, Chow Chows, or German Shepherds unless specifically advised by a veterinarian. These dogs are at high risk of dangerous overheating (hyperthermia).
Material Guide: Waterproof Ratings and Fabrics
| Rating | Performance | Best For |
|---|---|---|
| 20,000mm | Elite Protection | Extreme, sustained rain/snow |
| 10,000mm | Very Good | Most standard rainy conditions |
| 3,000mm | Moderate | Light to medium rain |
The Perfect Fit: Measurements and Design
Critical Measurements Needed:
- Back length: Shoulder blades to tail base (MOST IMPORTANT)
- Chest girth: Around the widest part of the chest
- Neck circumference: Around where the collar sits
Preventing Coat Matting: The Hidden Danger
Critical insight: Friction from clothing is a major cause of painful fur matting for curly breeds. The wrong coat can ruin a groom in one walk.
- The Solution: Look for Silk or Satin linings (like the Mikki Doodle Coat). These allow the hair to glide rather than knotting.
- Matting Zones: Always check behind the ears and armpits immediately after removing the coat.
Red Flags: Warning Signs of Cheap Materials
- Vinyl or PVC: Non-breathable, traps heat and moisture against the skin.
- Rough Mesh: Can act like sandpaper on fine-haired breeds.
- No Rating: If a brand doesn't list a "mm" waterproof rating, it is likely just water-resistant.
When to Use and Remove Dog Coats
⚠️ Overheating (hyperthermia) is a serious welfare concern.
A study by the Royal Veterinary College (RVC) found that Chow Chows are 17 times more likely to suffer heat illness than Labradors. Always remove coats when indoors or during active play. Signs of overheating include heavy panting, lethargy, or dark red gums.

Quick Decision Guide
Step 1: Assess coat type. (Short hair = warmth; Long hair = matting prevention).
Step 2: Check the weather. (Rain = 10,000mm+ shell; Dry Cold = Fleece/Wool).
Step 3: Prioritize fit. (Ensure multiple adjustment points at neck and chest).
