Is it a toy or a task? Why not both?! Gnaw-happy pups will love sinking their teeth in the Multipet Nuts for Knots Toys. Multicolored cotton rope with or without integrated rubber is twisted and knotted into a fun ball or tug toy that's just as much fun to fetch as it is to chew. Great toys for relieving separation anxiety in pets who are left home alone during the day. Available in multiple shapes and sizes.
