I had a dog who routinely _fell_ into the pond, and never managed to do it
any harm. EPDM is flexible enough to handle dog claws, imo.

another note - 6" is way too deep for birds. donna

Yes. I never had birds drown in my big pond, because they could always get
out, but I drowned a sparrow and a mouse in my tub pond before I managed to
devise a way for them to get out - and it never had 6" of water in it.
