Measure Your Dog Properly

Raincoat sizing varies wildly between brands. Measure your dog's back from neck to tail base, then add half an inch for the raincoat to sit properly. A loose fit lets water creep underneath. Too tight and your dog can't move freely. We made this mistake with our first test and had a soaking wet dog after five minutes.

Consider Your Climate

Light drizzle and heavy downpours need different products. If you live somewhere that rains constantly, invest in waterproof nylon like Ruffwear uses. For occasional wet weather and morning dew, water-resistant polyester works fine and costs less. Check your local weather patterns before deciding how much protection you actually need.

Check the Underside Coverage

The belly and inner legs get wet fastest because they touch grass and puddles directly. Look for raincoats that extend under the body, not just over the back. Many cheap options cover only the top, leaving the underside soaked. This matters more for dogs that drag through grass or play in mud.

Test the Fit with Movement

Put the raincoat on and watch your dog walk, trot, and play. Does it bunch under the armpits? Does it slip backward when they jump? Does it stay tucked when they shake? A good fit should feel almost invisible to your dog. If your dog can't move naturally, the raincoat will come off or create friction spots.

Factor in Drying Time

Thicker raincoats protect better but take hours to dry. Thin ones dry in under an hour but offer less protection. If you're going out multiple times daily, a quick-dry option saves hassle. If your dog goes out once or twice, the heavier raincoat with better protection makes sense.

Frequently Asked Questions

Do dogs actually need raincoats?
Most dogs have coats designed for rain, but short-haired breeds and small dogs get chilled in wet weather. Raincoats become essential if your dog shivers after getting wet or spends extended time outside in cold rain. They also protect your furniture and car interior from wet dog smell.
How tight should a dog raincoat fit?
You should be able to slide one finger under the chest strap comfortably. If you can fit three fingers, water will get underneath. If your finger doesn't fit at all, the coat is too tight and will restrict movement. Check the fit after your dog moves around for a minute.
Can I put a harness on under the raincoat?
Most raincoats have harness pass-through holes, but not all. Check the product description before buying if you need to attach a harness underneath. Otherwise, clip the leash to a collar or use a model with built-in anchor points.
How do I wash a dog raincoat?
Cold water and mild soap work for most raincoats. Machine wash only if the tag says it's safe, otherwise hand wash and air dry. Never use a dryer. Check seams and zippers before washing to make sure they're intact, since repairs are difficult once a raincoat starts deteriorating.
What size raincoat should I buy?
Measure your dog's back length from the base of the neck to the start of the tail. Most brands size by back length, so match that measurement to their size chart. Check Amazon reviews for that specific size because brands often fit differently. When in doubt, go with the larger size rather than smaller.

Bottom Line

The Ruffwear Cloud Chaser is the best raincoat if you want genuine waterproof protection that stays put during active walks. If budget matters, the Tooth and Honey option delivers serious water resistance at less than half the price. For rare rainy days and lighter drizzle, the ILEPARK raincoat works fine without the investment. Pick based on how often your dog gets wet and how tough your local weather actually is.
