I don't see how you get around a replacement. That water would shoot out like a fire hose and just destroys the site the pool's on, unless it's on concrete or asphalt. Had that happen to me--not a dog but a new, defective liner split a seam. Washed away much of the sand underneath. You'll have to fix the site, which means removing the liner. I'd say it's done.
