Top Dog Chews 6" Beef Trachea Dog Treats. A healthy alternative to rawhide, it's made of natural grass-fed beef trachea from free-range USA cattle that's 100% digestible. By helping to scrape away tartar and plaque from your dog's teeth, they support healthy gums and fresh, smoochable breath with every chew. Because they're a good source of glucosamine and chondroitin, they help support healthy joints from snout to tail. And since they're low in fat and contain no hormones, preservatives, steroids, antibiotics or chemicals, you can feel good about giving them every day as part of a balanced diet. Each pack comes with 10 hand-inspected and doggie-approved chews that are perfectly sized for most dog breeds.
