The indestructible ball lasted or rotti a big 15 seconds and was all over the house and she might be easier on it than the rottiXtreme Kong lasted the longest for my dog. But I put frozen peanut butter or yogurt in it with strips of carrots, beans or celery. The toy that has lasted the best for me was the almost indestuctable ball. I got the lrg size online at Petsmart. He goes bonkers over it. It took him awhile to learn to grab onto it but he mostly uses it as a soccor ball. You can also fill it with water to weigh it down. But my all time cheapest toys are a pair of old worn jeans with the legs knotted up and a tractor tire tied on a rope from a tree.
my boy got to that one above pretty quick, lasted a month or 2 tops.
just so you know - I do a lot of research on the products I sell and consider selling and as for the chuck-it the tennis ball that comes with have toxins (lead and bromine)I look for USA made quality & durability. My favorites are the Kong extreme, Nylabones & Tennis balls/Chuck it
