Puffed pig noses are a chewy dog treat made from air-dried pig snouts. The air-drying process makes the snouts swell up, reducing their fat content and making them less greasy. Puffed pig noses are high in protein and low in fat, making them a good option for dogs who like pork but can't have a lot of fat. They also contain natural oils that can help keep a dog's skin and coat healthy and shiny, and the protein can help promote strong bones and teeth. As a dog chews on a puffed pig nose, the chew will soften without breaking into pieces.
