Thank you for viewing! I am selling a new (unused) DFD X2 Boost floating jacket for dogs from EZYDOG, which sells dog supplies, including dog clothes, with the concept of 'NOW GO AND PLAY!' (Let's go out!). The color is red. The size is 3XS. Suitable dog breeds include small dogs (Yorkshire Terrier, Miniature Pinscher, Toy Poodle, Papillon, Miniature Dachshund, Shih Tzu, Italian Greyhound, etc.). [Reference] Size: Length: 21cm Chest: 37-52cm Neck (below): 22-27cm Based on animal engineering, it has a three-dimensional construction that fits the body, floats well and is stable, allowing for a wide range of motion and easy swimming. It also features three buckles for easy on and off, and is a lightweight and durable floating jacket for dogs. It also has a handle and D-ring, and is reflective. I purchased it new from a large pet supply store (9,900 yen including tax). The materials are neoprene, nylon, polyethylene foam, metal fittings, etc. Please note that although it is new, returns are not accepted after purchase due to various circumstances. Thank you for your understanding. Shipping will be via Takkyubin Compact, etc. We hope you will use it for active outdoor activities such as the sea, rivers, and lakes.
