I think it's a good idea. It openly illustrates the fact that wanting to spend time with a dog is NOT the same as being willing to take good care of a dog, and probably averts a lot of mistaken adoptions that would end in neglect or worse.

Also, from the human side, it lets humans who KNOW they wouldn't take good care of a dog experience the healing company of dogs, thus rewarding their willingness to acknowledge their limitations and count the dogs into their decision.
