1. Measure before: The muzzle is designed for mediumsized dogs with a mouth circumference of 2831 cm and a nostril diameter of 7 cm, suitable for breeds like German Shepherds and Golden Retrievers. The precise sizing ensures a snug fit—neither too loose to fall off nor too tight to cause discomfort. 2. Breathable and soft material: Made of breathable mesh, the muzzle allows airflow to prevent stuffiness. The edges and straps are crafted from quality nylon, which is gentle on the skin and nose while being robust enough to withstand daily pulling and wear. 3. Adjustable size: Featuring an extra Velcro fastener and a quickrelease front opening, this mesh muzzle is easy to put on, take off, and adjust for the fit. The adjustable loop connects securely to the collar, ensuring a nonslip fit around the nose. 4. Corrects bad habits: This muzzle helps prevent unwanted behaviors like swallowing foreign objects, biting, chewing, eating feces, licking wounds, begging for food, excessive barking, and even aids in managing aggression during training.
