Does anyone use the "scamper ramp" for their dog or some other type of pool escape device? I have had my new dog in the pool a few times and let her swim about 3 feet to the steps but I would feel better about having another exit for her in the deep end of the pool. I don't think she would jump in the pool on her own but I'm concerned she might fall in (she occasionally runs laps like a greyhound around the pool) or other safety tips? Thanks!
