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"

    I have to say this is my third life jackets I have two dogs but one grew out of hers and we added a new addition to our family! The life jackets are very well made and do a great job for our swimmers! They have great movement when they are in the water! The fit is easy and the adjustments are just as easy! I would recommend this to all your loved pets for the safety of them in the water! Thank you ezydog you guys ship super fast and your making a difference in the safety of our dogs! ❤️

    Poor Design, Belly part should have more of a attachment - straps move and flap always pops out. EzyDog says: Hi John - thank you for your feedback. This issue may be a symptom of a poor fit that can be resolved with adjustment. We would be happy to assist you. Please contact us at or 877-3EZYDOG.

    dog lifejacket

    Posted by amy on 5th May 2021

    My dog Kenai is a water loving lab. He swims in the river for 45 min at a time whether I'm in the water or not. He is approaching 10 years old and I wanted to give him a little added flotation and visibility in the water. This jacket fits him very well. good mobility while swimming and comfort while running on the beach. Very happy with the fit and performance for my active dog.

    DFD X2 Boost

    Posted by Chris on 25th Jun 2020

    This was a great purchase. It isn’t very bulky but it still gives my dog a lot of support in the water. I really like being able to Velcro the extra fabric around the buckles so there’s nothing flapping around and annoying my dog. I’d definitely buy this again.
