4-in-1 K9FITvest and Cooling Kit -- XL Only

4-in-1 K9FITvest and Cooling Kit -- XL Only




The patent-pending design of the K9FITvest allows natural freedom of movement, while conforming to your dog's body type. The K9FitVest is designed to be a 4-in-1 vest:

  • Fitness: Insert weights (sold separately) into the sewn-in compartments of the K9FITvest to add resistance to any canine workout program—turn an evening stroll into a calorie-burning power walk. Resistance training helps boost all five components of fitness: cardio, muscular strength, endurance, body composition, and flexibility. Weights will not shift or slide when inserted into the K9FITvest . Introduce resistance training gradually and safely with a low-level therapeutic weight program. See for K9FITVest exercise programs.
  • Anxiety Reduction: The compression fabric used to make the K9FITvest, along with a design that integrates weighted trigger-point compression aimed at encouraging better focus and movement, provides a gentle "hug" to help reduce anxiety. This sensory integration provides calming assurance without restriction. Our product testers, who had dogs that disliked thunderstorms, liked the K9FITvest better than their Thundershirts.
  • Cooling: Lightweight breathable material and cold packs (included with the K9FITvest) inserted into sewn-in compartments provide relief on hot days and can also help reduce back inflammation. Combine with chilled resistance weights (sold separately) for a workout with added cooling comfort.
  • Safety: The high-visibility reflective material accents of the K9FITvest ensure your dog is seen at night and in low-light situations.

Packaging: This kit includes the K9FITvest and 2 reusable cold packs. Weights are sold separately.

How the K9FitVest Fits: The K9FITvest is made of Tactel® and is designed to fit like a second skin, snug but comfortable. It should not be loose; otherwise, it will lose its effectiveness for calming and the weights (if you're using them) will shift and chafe while your dog is moving.

How to Measure Your Dog: Be sure that your dog is standing squarely, with head up, and is looking straight ahead. Measure the circumference of the dog's chest, (his girth) just behind his front legs, at its widest point. If your dog's measurements fall between sizes, please choose the smaller size.
