Thank you for viewing! I am selling a new (unused) DFD X2 Boost dog floating jacket 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 Terriers, Miniature Pinschers, Toy Poodles, Papillons, Miniature Dachshunds, Shih Tzus, Italian Greyhounds, 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 while providing balanced buoyancy and stability. It is designed for a wide range of motion, making it easy to swim, and features three buckles for easy on and off. It is a lightweight and durable dog floating jacket. 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.
