I have a doggy daycare area I’m just curious about the Palatability of the rubber rocks. Some freaky dog mignt eat it. The question is it manufactured with toxic properties? What is the products life span in the Houston Texas weather?

Our Playground Rubber Mulch is made of the same material that's used to make the soles of shoes. It would be toxic, but will not cause any life-threatening harm since dogs often chew on the soles of shoes without any significant health issues to them. Rubber lasts forever, and so will this product. The color may fade over time.
