Bea likes to try to eat her pool too. Those little chunks they shear off are SHARP! I stepped on one the other day and thought I'd been stung by a bee. God knows what a chunk of puppy pool would do to a dog's intestine! Augh!
I'd be scared of chunks causing an obstruction too...I've read too many stories of that happening that I'm super paranoid if HRH chews anything enough to get a chunk off.
I now worry so much about my dogs swallowing something that would cause damage or a obstruction. I can't believe some of the things I let earlier dogs chew! God protects the naieve!
