Size: S I mistakenly assumed that size S would be too small for my 2.6kg Maltese, and despite checking the size, I ended up buying the wrong one. Since it's a hygienic product, I can't return it, and it's become completely useless to me, so I'm putting it up for sale. Purchased on 2025/10/8. I think it would fit dogs around 4kg to 8kg. Examples include Boston Terriers and larger Toy Poodles. It's a cute black gingham check with a biscuit pattern. I think it would suit both boys and girls. The fabric is also sturdy. It's a great set with a harness and leash. Please check the detailed size information in the images. Retail price: 4000 yen (tax included) #HalloweenOnMercari
