A couple years ago I started walking two Vizslas, Miles and Oliver. 
Both dogs were picked up at Miles' house, where there were two small children, and the house was very childproofed. A couple weeks into our service, I went to pick up the dogs and the nanny wasn't home and the dogs were locked behind a baby gate in the kitchen. I spent a solid 10 minutes trying to figure out how to open the damn baby gate.
I knew the baby gate was intended for the kids, not the dogs, because these dogs routinely jumped 4' fences at the dog park. It was actually their main way to enter and exit the park. So here I am, defeated by the baby gate, and trying to figure out what to do with these dogs. Knowing how much they like string cheese, and jumping over things, I decide my only option is to teach the dogs how to jump over the baby gate. It only took a few minutes and we were out the door.
Years later, I am housesitting at Miles' house and am still defeated by all of the child proofing things. Apparently child proof = Kelley proof. These baby gates, electrical plugs and cabinet thingys are way beyond me. Apparently teaching dogs agility on a whim isn't.
