We have got the wire dog muzzle with rubber covering by ForDogTrainers UK. We made some research and found that wire muzzles were more durable and safe for bites (Jett has never biten but we are responsible to prevent it taking into account the fears). We also like that it allows to gve treats and free air (very important). Also we like the wide room for panting, that is very important for Jett for his wide pant (it helps dogs to regulate the body temperature / cooling) and that he is very active.
