The Lifesaver Chew Toy is for heavy chewing dogs. Measures 7". For every purchase, the manufacturer, Jax & Bones donates 10% of the proceeds to rescue groups to help homeless animals find their forever home. Hand-tied and dyed using non-toxic vegetable dyes. As dogs chew the toy, the rope toy frays and acts like doggie dental floss. Dip it in water and freeze it to cool down a hot dog or to soothe a teether.
