Lamb Lung Filets are all-natural lamb lung baked into a crunchy texture bursting with a meaty flavor. Sourced from grass-fed, free-range lamb, our Lamb Lung Filets come from ranchers in the USA and New Zealand. But this high-protein, low-fat treat doesn’t just taste like meaty heaven. Each chomp helps support your dog’s overall Dental health by gently scraping away plaque and massaging their gums as they chew. Training a puppy or teaching an old dog new tricks?
