Trixie nylon muzzle with mesh is suitable for brief use, such as a visit to the vet or an outing. It does not cover the dog's muzzle entirely, and thanks to the mesh inserts, it allows for better and easier breathing. Because the neck strap is fully adjustable, via the snap buckle, and the circumference of the muzzle is not fixed, but can be adjusted, it prevents circulation problems and remains absolutely soft for the animal without squeezing the animal's throat in any way. Available in five different sizes, depending on your Fido's size: Size;Snout circumference:Webbing around the neck: S;14-18 cm;12-31 cm, S-M;14-22 cm;18-44 cm, M;20-28 cm;22-38 cm, L;22-32 cm;26-42 cm, L-XL;22-34 cm;28-46 cm
