We know never to compromise when it comes to the water safety of our pets, so we use only the highest grades of materials in all our dog life jackets. Whether you're teaching your dog to swim or simply using it as a safety precaution, the DFD X2 Boost will help your dog stay safe around water.

A Dog Life Jacket Designed for Function, Safety and Comfort

The DFD X2 Boost features a unique fixed collar adjustment system, which only has to be adjusted once. The fixed collar on the DFD X2 Boost maintains the same positioning at all times, yet still offers ample adjustment. All webbing is contained within neck strap, meaning there's no loose webbing to irritate your dog.

The Ultra-Buoyant foam is strategically positioned around the vest, including the section under the dog's belly. This keeps your dog upright and in a natural swimming position at all times. Unlike other vests, the DFD does not hinder your dog's natural movement and can be fastened/removed easily and quickly.

New Dog Swim Vest Design with New Features

A life jacket that fits the dog's body type allows them to swim with confidence and run more freely. The geometry of the DFD X2 Boost has been meticulously crafted to fit comfortably around any dog type, with panels designed to taper to the shape of a dog's torso.

A grab handle is situated at the top of the life jacket for quick control over your dog. Reflective piping is used throughout for extra visibility at night. The revolutionary neck adjustment contains buoyant foam, to help keep your dog's head above water.

Why buy a Dog Float Coat?

A dog swim vest has several main purposes. Recreation for dogs that spend a lot of time in and around the water or for owners who take their dogs on boats. It's also great for dogs who struggle to swim and is recommended for use in Hydrotherapy rehabilitation.


For best fit, measure the girth and length of the dog. Girth will take priority when selecting a size.

The girth being the area behind the front legs and around the body.

The length being the area from the neck to the base of his/her tail.

If your dog is between two sizes, choose the smaller size.

The DFD X2 Boost does not need to cover your dog's entire back length to be effective.

Size Weight (lb) Girth (in) Length (in)
XS 15-25 18-21.5" 12-18"
S 20-45 22-25.5" 14-20"
M 40-60 26-29.5" 16-22"
L 60-90 30-33.5" 18-24"
XL 90+ 34-41" 20-26"

    Great fit and easy to put on and off. Good flotation. Sleek design for no swimming hindrances. Handle on the back offers a good grip for hauling a big (or small) dog onto a surfboard or up on a dock. Ezydog rocks!

    Love it

    Posted by Lindsey A on 14th Aug 2023

    We now have our second GSP puppy, and the first one did not float or swim terribly well to start so I knew I wanted a life jacket for this one and did a lot of research. We have a pool and a pond and it only took three weeks for her to jump in. I am SO HAPPY with how well she can float and swim in this. She can safely swim on her own without assistance in this. She also seems comfortable enough to run around in it when she jumps out. It’s a little too bulky to have her wear full time when outside as it’s 98° (Florida) but soon it’ll be ok for her to wear on walks to the pond for spontaneous swims. She’s a 3mo 15lb GSP and I got XS. Fits well and she still can grow for a few months and fit it.

    Highly Recommended

    Posted by Claudia on 13th Jul 2022

    This is a top quality product! Our pup (Amstaff/boxer mix) has a weirdly shaped body that makes fitting difficult. The sizing guide was perfect (if between sizes, go down as recommended) and provided ample opportunity for adjustment. The slim profile made it super comfortable for a full day at the lake. It’s pricey but worth the cost and expect it to last a long time.

    DFD X2 Boost

    Posted by Unknown on 10th Jun 2022

    We have a German Shorthair who loves the water. After several misfires with other brands, this vest fits her body type and activity level very well. Size M works for her at around 45 lbs. Would give 5 stars if there was a better system to tuck away or dispose of excess webbing. As it is, you fold the excess back on itself and use hook/loop to close it into kind of a wad next to the buckles. Perhaps I’m too picky but aside from these bundles of webbing, the vest looks very sleek and form fitting.

    I’ve tried other vests but this one fits better, it made more durable, and works well for different breeds and body types. Will be buying another one.

    Best life jacket for dogs

    Posted by Ashley on 28th May 2022

    After testing and owning other dog life jackets, this has by far the best combination of features and safety. Dog swims great in it and her body position in the water looks the same or better as it did with other bulkier life jackets. She is noticeably less hot in this one on the boat and most importantly, it works great as a harness at the marina. The leash clip is strong-other premium jackets cheaped out with a plastic D ring but this has a metal ring and is very securely stitched. I also really appreciate how easy it is to get on and off, the high visibility color and reflective features, and the grab handle. The straps tuck away and no buckles or webbing rub on the skin. Really couldn’t be happier with this life jacket and my dog is happy wearing it!

    Wish the XL was built for more lean athletic +90lb dogs.

    Posted by Kristin on 19th Apr 2022

    I purchased the Large and Extra Large for my 95lb Dogo Argentino. The Extra Large was too bulky. My dog couldn't comfortably sit down bc it's a bit long but it is recommended for the +90lb dogs. So I kept the Large and sent the Extra Large back.

    great customer service n well made

    Posted by Deb on 7th Sep 2021

    Had a sizing issue. Bryant was very quick to connect w me and fix the issue. Item is really well built n seems very durable. My fem 64 pound A. Bull Dog wears it fetching and swimming at the river. Definitely helped her to a more horizontal swim position w better buoyancy than her prev lifejacket. Design is not restrictive so she didn't seem to notice it on at all. Item comes w display placard that has more detailed sizing info w much wider range of measurements. I would suggest this info would be helpful for online purchasing when you can't try product on for size in-store. We have the yellow jacket and it looks awesome.
