Dog raincoats with leg cuffs usually perform well in terms of waterproof sealing. The following is a specific analysis:
The leg opening design reduces the possibility of rainwater seeping through the legs by tightening the edge of the trouser legs, thereby enhancing the overall waterproof effect. Some brands, such as the four-legged full cover one-piece waterproof raincoat from Wu Kui Shou, feature elastic trouser legs that better fit the dog’s leg shape and prevent rainwater from flowing in. Meanwhile, the drawstring design can also prevent the raincoat from being blown up by the wind when the dog is active, further enhancing the sealing performance.
However, the waterproof sealing performance is not only determined by the design of the tie opening, but also closely related to factors such as fabric selection and seam treatment. For instance, raincoats made of waterproof TPU material or with waterproof films usually have better waterproof performance. In addition, detailed designs such as a waterproof zipper on the back and double-layer guard plates can effectively prevent water from seeping through the back.
