Aww that's too bad, I didn't labbys were that bad well if you do decide to replace the pond and and the wildlife will thank you if you do then you will have to come up with a plan to keep the dog off it.
This is ironic,
I bought a kids paddling pool for the dog for £3 filled it up and the dog didn't want anything to do with it..
She drank the water like it was a giant water bowl but not go in it, now will she keep out of the pond in the same way..NO..lol
