I copied and pasted the email I got here (I'm not the author) but think this idea is insane!

Animal Planet is 'casting' for a new 'reality' show called "Who Gets the
Dog?".

Basically they pull a dog out of a shelter, shuffle it around for 3 days
with 3 different families (24 hours each), and then somehow the dog is
supposed to "pick" which family it wants to live with. The only
safeguard it offers the dog is that "You must not have been CONVICTED
(my caps) of (a) any crime that includes cruelty to animals, or (b) any
felony under any jurisdiction in the United States or any other Country.
And "You must be ready, willing and able to adopt and care for the dog
involved in the production of the series."

If you think that this is not the best thing to put a dog through for
the sake of 'entertainment', please send a comment to them to let them
know what a stupid idea this is and how inhumane it is to put a dog
(particularly a shelter dog with who knows what having happened to end
him up in a shelter in the first place) through this kind of stress and
confusion. Can you imagine the health and behavior problems something
like this could cause the "lucky dog", as they say on their website. I
wonder if they would do this to a four year old foster child. And we all
know that it's not likely to be dog savvy people who would do this. What
happens to the dog after the show and the novelty has worn off with the
family "required" to adopt the dog? And not being "convicted" of an
animal crime is little reassurance since most animal abusers are never
caught, much less convicted.
