All pet shops should do this at least once every year.
There are so many shelter dogs that go unwanted every year. The shelters and pounds are becoming over run with these little guys meaning something really needs to be done about it.
This pet shop had a really clever idea to put some dogs from a shelter in their shop to see if they attract any interest. Not only did people want to re-home the dogs, they even offered to pay.
What a great idea.
