We looked hard and long at the SwimEx but could not figure out how to get steps in them to help the dogs get in and out. Everything we considered would have taken up too much space and money was an issue.

Thanks for the info on the Gaco Shield. We had put down some gym and wet room matting made by Kieffer Flooring. It worked well for bare feet but was far too slick for dog pads. It now graces our kitchen floor. Definitely non-skid when dry but not useful when wet. Now we have an indoor-outdoor rug on the pool deck in the area where dogs enter and exit and block off the rest of the deck when we have swimming dogs. No running allowed!

We're getting a little off topic here. Hope you find a suitable pump for your setup.
