Buffalo hide stitched over layers of natural wool felt with heavy cotton jute thread — the same build Tall Tails uses across the natural leather line, and the reason these outlast a plush toy by a wide margin. No toxic chemicals, artificial coloring or fake flavoring in it. 4", for small dogs up to about 25 lbs that like to retrieve and tug. Spot clean only. Worth being clear about: this is a fetch and tug toy, not a chew toy — it is not meant to be left with a dog that grinds, and it should come away once pieces start to separate.
