I remember there were a few rescues who would let you 'rent' a dog for a day,but they weren't charging for it,and their idea around it was for people who weren't sure if they were ready for a full time dog. I don't think this girl should making money off of this.
The rescue's intent is to find homes for the dogs.
The problem as I see it is what happens to the dogs once they are no longer puppies? The dogs are kept at her aunt's house. Who is responsible for these dogs? These aren't robots, they are living breathing creatures.
I wasn't really clear on that either when I watched the video. She says that she gets the puppies from people who no longer want them,but never mentioned what happens to them after a certain time frame.
