Actually yes it is enough. If you keep the gate closed the dogs rarely get out and nobody gets hurt. I am reminded of when I got married and my wife moved in a few months later (she was my GF at the time.) She hadn't been moved in a month and she starts on the "we have to put a fence around the pool." My response was there is an 8 foot fence around the whole yard. She clarifies.. she wanted one of those kid proof fences around the pool. Because we weren't married I told her hell no.
She starts in on all the "it only takes a second for a child to drown" nonsense. I came back with "no it takes several minutes for a human being to drown." Also if people just watch their damn kids the kids never drown. All the stories feature someone who "just went inside for a minute." Uh no you didn't. And even if you did.. WHO LEAVES A TODDLER ALONE AT A POOL FOR ONE SECOND!??!!? When our youngest was born she learned to swim before she could walk. Started her in lessons at about 6 months. She was never left alone by the pool until she was about 20. Needless to say, she never drowned. In the case of Zeke's dogs.. I seem to recall on at least two of the instances he was not home and someone else let them out. I can hold him responsible for hiring idiots to work on his house.. but that's about it..
