My foster pup is an extremely super strong chewer and quickly chewed through everything we tried. He was always so sad when we’d take the remnants away. Then, finally, we tried the Ruff Dawg indestructible floating ball. Hallelujah! Almost three weeks in, and the only wear and tear is some surface scratching. He takes his ball everywhere - to bed, on walks, out to do his business. And he loves playing fetch with it, inside and out. It is his emotional support ball, as well as his favorite thing in the world.
