I want to try to get my GSD (German Shepherd Dog) on the Mojo. We bought it used, but wife is saying NO EFFING WAY, he will damage the vinyl and the swim platform. I figured lots of towels and short cut nails to help with vinyl, but how do I get him in the boat after swimming? 100lbs of wet dog is hard to pickup if he cannot climb back in on his own. I can sink the rear while we swim, just curious how others do it with large breeds.
