Hi, I have an 11 month male Goldie who loves digging & wallowing in mud & water.
I am thinking of getting him 2 small 'paddling-pools' - 1 with sand & the other with water. My question is: what should they ideally be made from - fibre glass or heavy guage plastic? Although he is not much of a chewer, obviously my chief concern is that of safety.
Thank you.

With my Labradors concrete is only just hard enough!!!:) Seriously, it's not the teeth that are the problem. Claws are the main culprits.

Regards, John
