All Pet Qwerks components are sourced in the USA! Non-toxic. Not edible. Allergen-free. Contains no peanuts. Always supervise pets while chewing  and remove from the pet if it is consuming the chew or if damaged. Chew marks or small granules are safe and to be expected. Giving your dog non-edible chews and bones also massages their gums and provides scraping action on their teeth, much like a dental hygienist descaling the plaque from human teeth. It helps healthy chewing and makes for a more entertaining experience. It discourages destructive behavior when they get bored. Pet Qwerks offers a big variety of flavors, shapes and sizes of nylon chews
