underDOG Pet Life Jackets

Ergonomically designed aid for swimming canines

The new underDOG is the first ergonomically designed aid for swimming canines. With 90% of the flotation in the water under the chest and neck, the underDOG supports a natural swimming angle. Allowing the dog’s hindquarters to float lower improves fido’s efficiency in the water. Other features include top mesh for cooling, two straps for lifting the pooch easier, adjustable length, generous reflective trim, tough Cordura® construction and a leash attachment. Red/Mango.

      We take our pup out on our boat almost every weekend now! This particular life jacket gives her more freedom to swim and run around without have the life jacket move around. She loves it!!

          Comments about underDOG Pet Life Jackets:

          I love this dog lifejacket. Having the flotation beneath the body is much more comfortable and functional for the dog to swim. Our dog actually fell between the dock & the boat and the flotation worked beautifully. Even though he was surprised at finding himself in the water, the lifejacket helped in the moment & he quickly found himself back on the boat. The 2 handles are excellent for easily lifting the dog out of the water.

            after figuring out the adjustment our dog likes to wear the vest. it is great when big seas hit the boat. makes me feel at ease when we are in heavy seas. also good to leash her to the helm. not so good when she wants to lay down and chill but not needed in light weathers.....

              Comments about underDOG Pet Life Jackets:

              We bought this life jacket for our 8 wk old Golden Retriever puppy. He was comfortable in this from the start. Because the neck and body pieces are seperate and connected by an adjustable piece, we were able to use this jacket in a size Small through the entire season as our 10 lb pup grew to 36 lbs! We are getting one in a large for next year's sailing season.
