Perfect PFD for PT water treadmill therapy

Needed a PFD for our large dog while doing water treadmill therapy. This works perfectly for that! And it allows for full range of motion during his PT while recovering from surgery. Recommend this design for anyone who needs a PFD while still allowing full range of motion for any activity for their dog!

Love this life jacket for

Love this life jacket for my dog. Love that the floatation is underneath as it helps push the dog up instead of down in the water. It really helps my puppy have confidence in the water.

By Leslie R.

Love this life jacket for my dog. Love that the floatation is underneath as it helps push the dog up instead of down in the water. It really helps my puppy have confidence in the water.

Experience the joy of water adventures with your furry friend by your side, thanks to our Mustang Survival Underdog Foam Flotation Vest, a PFD (Personal Flotation Device) designed explicitly for dogs. This PFD incorporates a unique cape-style design, offering four adjustment points that promise a secure fit for every breed.

Understanding your pet's needs, this dog life jacket is crafted to support their natural swim angle, allowing maximum mobility. The buoyancy is thoughtfully concentrated under their neck and chest, aligning with their natural buoyancy point. Using USCG-approved fabrics, including robust Cordura on the belly and neck panels, we've made sure the vest offers abrasion resistance. This makes the Underdog an outstanding choice to keep your pet safe, comfortable, and mobile on the water.

A cool, breathable 3D mesh on the back enhances comfort, while reflective panels on the vest boost visibility in low light conditions. A sturdy carry-handle and leash attachment point further underline the Underdog as an excellent flotation device for your four-legged pals. This PFD is available in multiple sizes to suit different dog sizes and weights.

Extra Small (XS): Perfect for the littlest pups! Ideal for dogs measuring 12" to 18" in girth and weighing between 2 lbs to 12 lbs.
Small (SM): Great for those smaller breeds. It fits dogs measuring 18" to 24" in girth and weighing between 12 lbs to 24 lbs.
Medium (MD): Designed for mid-sized dogs. This size fits dogs measuring 24" to 30" in girth and weighing between 24 lbs to 60 lbs.
Large (LG): For your larger canine companions. It fits dogs measuring 27" to 36" in girth and weighing between 60 lbs to 90 lbs.
Extra Large (XL): Made for the biggest breeds. Ideal for dogs measuring 33" to 44" in girth and weighing between 90 lbs to 120 lbs.

Care Instructions
Every Use
Rinse after use, especially after use in salt water. Hang to dry away from sunlight.

Occasionally
Hand wash in mild detergent to help prevent mildew, rinse and hang to dry. Mustang Survival likes McNetts Wetsuit and Drysuit Shampoo. McNetts MiraZyme or Sink the Stink is good if your PFD has developed a funk, or you can use all natural Surf Remedy to shed the stink!

Seasonally
Inspect PFD for tears and holes, be sure zippers and buckles are working properly. If material is faded the fabric has probably lost strength. Foam deteriorates over time, so test your PFD and be sure it keeps your mouth out of the water. If you notice fraying of fabric or straps, serious UV damage, or crushed foam, please discard and replace with a shiny new MTI PFD.
