It is ten to eight, the rain is coming in sideways, and the dog has planted all four feet on the doormat with the face of someone being asked to swim to work. You get him out eventually. Forty minutes later he is back, soaked to the skin, shaking a fine brown mist across the hallway wallpaper.
A raincoat will not make every dog love a wet walk, but it does change what comes home with you. The best dog raincoat is a light, waterproof shell that covers the back and chest, fastens without a battle, and leaves room for a harness. Fit matters more than the brand name: a coat that rides up or rubs under the legs gets shrugged off, or worse, gets your dog refusing the door entirely.
The quick version
For most dogs, a lightweight waterproof shell with a chest panel and a harness slot does the job from autumn to spring. Thin coated, older or small dogs that feel the cold do better in a fleece lined rain jacket. If your walks happen in the dark, which in a British winter is most of them, pick something with reflective trim or go for full hi vis.
What makes a good dog raincoat?
Water resistant coats cope with drizzle and give up in a proper downpour. Look for taped or welded seams and a fabric described as waterproof rather than showerproof.
After that, the details that actually matter day to day:
- Chest coverage. Rain and puddle spray hit the underside first. A coat that only covers the back leaves the belly and chest soaked, which is where the smell lives.
- A harness hole or lead slot. You want the lead clipped to the harness, not fighting the coat. If you walk with a no pull harness, check the slot lines up with the clip you use.
- Easy fastening. Wide Velcro or a buckle across the chest beats a coat you have to feed paws through, especially with a wriggly dog and cold fingers.
- Breathability. Cheap plastic coats trap heat.
A hood is optional. Plenty of dogs hate them, and in my opinion they are mostly there for the photo.
How to measure your dog for a raincoat
Sizes vary wildly between makers, so ignore the “medium” label and measure. You need two numbers and a soft tape measure.
Back length runs from the base of the neck, where the collar sits, to the base of the tail. Chest girth goes around the widest part of the ribcage, just behind the front legs. Compare both against the size chart. If your dog falls between sizes, deep chested breeds usually need the larger one, while slim dogs often swim in it.
Once it is on, you should be able to slide two fingers under the straps. Watch the armpits on the first few walks. Rubbing there is the most common reason a dog starts sitting down mid walk.
Three raincoat styles worth a look
The lightweight waterproof shell
This is the everyday option and the one most dogs will tolerate best. Thin, packable and quick to dry, it suits anything from a soggy park loop to a long walk in mild weather. Look for a belly panel and a harness opening. A waterproof dog raincoat with a harness hole on Amazon is a good place to start comparing sizes.
Best for: medium and large dogs with decent coats who just need to stay drier.
The fleece lined rain jacket
Greyhounds, whippets, small terriers and senior dogs often get cold as well as wet. A shell with a fleece or quilted lining handles both. The trade off is drying time, so if you walk twice a day in the wet, owning two is not as silly as it sounds. Have a look at a fleece lined waterproof dog coat on Amazon if your dog shivers on the way home.
Skip if: you have a thick double coated dog. Huskies and shepherds overheat fast in a lined coat.
The reflective or hi vis coat
From November to February, a lot of dog walks happen in the dark or close to it. A bright yellow or orange coat with reflective strips makes your dog easy to spot for drivers and cyclists. A reflective hi vis dog raincoat on Amazon doubles as a rain shell for most weather. Honestly, this is the one I would choose first if your walks cross roads after dark.
Getting a reluctant dog to wear one
Some dogs freeze the first time a coat goes on, walking like a cat in socks. That is normal, and it usually passes if you go slowly.
Start indoors when nobody is in a rush. Let your dog sniff the coat, drape it over their back for a second, treat, and take it off. Next session, fasten one strap. Build up to wearing it around the house for a few minutes before you ever head out. Pair it with the lead and treats so the coat starts to mean “walk”.
If your dog is already a bit wound up at the door, keep the coat routine calm and boring. The same slow, rewarded steps from loose lead walking practice work well here: reward the calm moments and wait out the silly ones.
After the walk: drying off and coat care
Even the best coat leaves legs, paws and head wet. Keep an old towel by the door and do a quick rub of the paws and belly before your dog hits the sofa. Wet fur that dries slowly in a heavy coat can tangle, so a short brush once they are dry helps, especially during the autumn moult. Our guide to the best dog brushes for shedding covers which tool suits which coat.
Check between the toes on muddy days too. Grit and wet fur there can make paws sore. If nail trims have slipped, our roundup of dog nail clippers and grinders may help.
Rinse mud off the coat, hang it away from direct heat, and wash it cool now and then. Hot washes and tumble dryers wreck waterproof coatings faster than any rainstorm.
Quick questions
Does my dog really need a raincoat? Not every dog does. Healthy dogs with thick coats cope with rain fine. A coat helps most with thin coated, small, elderly or unwell dogs, and with anyone tired of washing a muddy belly every day. If your dog seems unusually bothered by cold or damp, or is stiff after wet walks, have a word with your vet.
The rain is not going anywhere until spring. A coat that fits, a towel by the door, and a dog who has learned that the jacket means a walk will make those grey mornings a little less soggy for both of you.
