Swimming Pool?!?

I got a blow up pool for my grand kids to play in on hot days here at my house.  

Cooper enjoyed the idea of having a pool.  He couldn't figure out how to get in the pool.  Every time he put his paws on the side of the pool the thing kind of started to collapse.  

This worried Cooper a little bit, so I think we need to make some kind of ramp up and over the side for Cooper.  He's going to pop the pool if I let him figure it out on his own.
