Mandate a breeding license for all dog owners who breed their dogs and to limit breeding on dogs.

In the U.S. 2-4 million dogs and cats are euthanized per year in animal "shelters". Most of these animals are healthy and adoptable but due to a high amount of animals coming into shelters and not enough being adopted out they are being euthanized after a limited amount of time. There is an over population due to owners over breeding their animals.
Please mandate a Registered Breeding License for anybody who breeds their dogs. The owners who do not have a breeding license should have to get their animal neutered/spayed at a discounted price.
This is a huge problem in the U.S. and around the world and it's past time to take action.
So, please President Obama, a fellow dog lover yourself, mandate a Dog Breeding License to help stop over population and unnecessary euthanasia.
Thank you.
