Hi Phyllis,
We're sorry to hear about your Ice Mat. A team member will be reaching out to you directly to follow-up.
To clarify, the liquid gel inside the Ice-Mat is NON-TOXIC, so it is not harmful to dogs.
The Ice Mat's, sadly, are not indestructible, which is why we state on the Ice Mat's warning label 'do not leave unattended if your dog is prone to chewing' and caution to be careful with use as sharp claws can puncture the mat.
Once again, we're sorry to hear about your mat, and we'll be in touch to follow up.
