What do you think of this television program format (which involves dogs)

This week a new tv show will air on the Dutch television we get bombarded with teasers the last days.
A family (with children) are going to take a dog from an animal shelter.
They will get six dogs visting them in their house and in a week time they have to send four away that will be decided after the dogs have to show their character, their behaviour, interaction, etc..
Then, from the two remaining dogs the family will choose the ‘winner’.
That describes the teaser that we are shown.
What are your first thoughts on this format?
