This is IT the one ball that built to last!! Our ball is super bouncy for the doggos that love to show off with epic catches! It is tough for the doggos that love to destroy and chew everything and it floats for the fun times on the water. It also comes in a natural cotton bag to keep that slobbery wet ball secure. The bag can be used to hold the adventure treats and poop bags for the daily outings. This is our large size made for kelpie size onwards
