I purchased this, but it seems too small for my 5-month-old Golden Retriever and Siberian Husky mix, so I'm putting it up for sale. I've only taken it out of the package, so it's brand new. The following is the previous seller's comment: Good ventilation and doesn't slip! High-quality specifications that prevent slippage due to head shaking or large movements by securing the face area. Special large mesh is used to eliminate heat buildup by covering the mouth area. It is well-ventilated and can be used comfortably and gently on the body. Prevents causing trouble to others when going out, such as for walks or travel, and looks stylish! This is a muzzle that combines functionality and fashion. ● Product Features 1: Easy to attach with a one-touch buckle 2: Fine size adjustment is possible 3: Safety is improved by carefully sewing the connection part with the muzzle 4: The string part uses high-density nylon material with high strength 5: It is non-slip and has excellent breathability ■ Material: Polyester + Nylon I bought this for my dog, but I made a mistake with the size, so I'm selling it.
