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.

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"

    Border Collie Approved!

    Posted by Philip Doll on 31st Jul 2021

    I have a super swimmer Border Collie and wanted a DFD for when we play in deep water off the boat. The X2 Boost is perfect! Fits well and doesn’t restrict movement. He didn’t mind having the X2 on and loves being able to jump off the boat. The yellow color looks great on him! Highly recommend for active dogs!

    Great lifejacket - our Golden Retriever loves to go swimming off the boat - makes it easier to get her on and off the boat. And our Pomski likes to linger in the lake with it on - gives him a sense of security. Also excellent customer service when we had an issue they were so prompt and kind. Would recommend

    Loves it!

    Stela (75lb GS) would do the dolphin swim, (not really swimming, more like jumping in the water) but she loves to go in. So we took her out in the boat and put her new lifejacket on and she swam away! The carry handle is great for helping to pull her out of the water later and she seems so much more confident in her swimming now. We have only used it the one time so far but its great, lightweight and safe. She can freely move all of her limbs with no issues.

    I have goldens that swim. They are good swimmers and I was taking them to a river and wanted to make sure they were safe. The life jackets were great, not in their way to jump and swim. The best thing was that it kept their heads high out of the water so they did not ingest a ton of water. It is great for my older dogs as well as my young ones. Great decision to purchase this, even though my dogs are strong swimmers.
