Mile High Life Waterproof Dog Raincoat (Red, X-Small) with Harness – Full Coverage Rain Jacket for Small Dogs

What it is and why you’d want it

This Mile High Life waterproof dog raincoat is designed for small-breed dogs who need proper coverage when the weather turns. The big idea is simple: a rain jacket that keeps rain and messy outdoor conditions off your pup, while also building in a way to keep them secure during walks.

Unlike basic “hoodless ponchos”, this one uses a four-leg, full-coverage approach and includes an integrated harness concept. In practice, that means less faffing when you’re getting ready to go out—especially if your dog is the sort that won’t stand still while you wrestle with separate rainwear and a separate harness.

It also has a reflective strip intended to improve visibility on darker walks. That’s one of those features that may feel minor indoors, but becomes genuinely useful once the evenings start getting darker.

Key features that affect everyday walks

A few design choices here are clearly aimed at making rainy-day walks more manageable.

First, it’s positioned as waterproof outdoor fabric. The goal is to keep your dog comfortable and dry even in bad weather. As with any rainwear, the fit matters a lot—if it’s too loose, water can find gaps, if it’s too tight, it can affect comfort and movement. So this is the kind of item where getting measurements right before buying really pays off.

Second, it’s reflective. The reflective stripe is meant for higher visibility at night and in poor conditions, which can be reassuring if you walk near roads, paths with low light, or early mornings.

Third, it’s described as a 2-in-1 harness & raincoat design. The harness is adjustable and sits in a way that should make leash attachment easier, without the need to add a separate harness on top of the coat.

Fourth, it uses an adjustable, four-leg layout. Neck and waist haul lines with adjustable drawstrings, plus elastic wraps around the legs and tail, are all part of how it aims to stay in place.

Fit notes (and where people can get caught out)

This is an X-Small size, built for small breeds, but the manufacturer advice is clear: measure your pet first.

For size XS, the guidance provided is: - Chest: 15.5"–17" - Back length: 11.4" - Neck: 11.6"

Two practical points from the description are worth taking seriously. If your dog’s measurements fall between two sizes, you’re advised to choose the larger one. Also, chest girth and back length are the priorities—so don’t be tempted to “eyeball” it if your pup is compact but has a longer back, or the other way around.

This kind of coat also depends on your dog’s proportions. If your dog has a particularly unusual shape for their size (short legs, a very long back, or a thicker coat), it may be harder to dial in a comfortable fit.

What to expect on rainy days

In day-to-day use, the main benefit you’re paying for is full coverage. A four-leg design is meant to help protect from rain, mud, and wind more effectively than single-panel coverings.

Micro-scenario: imagine a wet evening walk where your dog usually ends up with a soaked chest and a muddy belly area. With a full-coverage raincoat that has leg and tail elastic wraps, you’re aiming to reduce how much of that mess reaches their fur. Add the reflective stripe, and you also get that extra layer of visibility when you’re on paths with poor lighting.

That said, no raincoat is magic. Even with waterproof fabric, it can only protect what it covers, and movement will always matter—especially around the legs and tail where elastic helps, but where incorrect sizing can still allow water to creep in.

Pros and what stands out

What stands out day to day

• Waterproof design intended to keep small dogs comfortable and dry in poor weather.
• Reflective strip for improved visibility on darker walks.
• Full coverage approach with a four-leg design, aiming to protect from rain, mud, and wind.
• Adjustable harness built into the raincoat concept, with leash attachment made easier.

Where it may not be the best match

Worth noting before you buy

This is aimed at small-breed dogs, and it’s sized specifically (XS with defined chest/back/neck measurements). If your dog is bigger than the XS range—or if their shape doesn’t match the typical proportions this kind of coat expects—you may end up fighting fit and comfort.

Also, if you’re someone who already has a harness you love and don’t want to change setup at all, the integrated harness design may be less appealing. It can be convenient, but it’s not the same as using your existing harness system unchanged.

Care and buying checks

Before purchasing, check the sizing guidance and measure your dog properly. The description explicitly asks you to prioritise chest girth and back length, then use the neck measurement as part of the fit.

Another sensible check: consider whether your dog has any features that might affect fit, such as an especially thick chest, very long/short back, or a tail position that changes a lot during movement. The elastic wraps and adjustable drawstrings are there to help, but they can only do so much if sizing is off.

Is it worth it?

Final verdict

It’s worth considering if you want a waterproof, full-coverage raincoat for a small dog, and you like the idea of a 2-in-1 harness-and-raincoat setup for quicker, less fiddly walks—especially when evenings are dark and you’d benefit from a reflective strip.

You may want to skip it if your dog doesn’t fall comfortably within the XS measurement ranges, or if you’re very particular about using a specific separate harness and don’t want an integrated approach.

For most people, the deciding factor here will be fit. Get the chest girth and back length right, and this kind of coat can be a practical way to keep the mess and wet weather from dominating your walks.
