As long as it continues shelters are going to keep getting filled up with dogs that wind up being euthanized instead of living in their deserved forever home.
We are seriously overpopulated with dogs. People dump them on sides of roads, decide a puppy is too much to handle, or just don't want to deal with their disabled or senior animal. The list goes on. I've yet to establish how you can own an animal for a day much less 10 + years and drop it off at a shelter knowing fully well that it will probably be euthanized. And I'm not talking about loving owners who for sad circumstances have to rehome their animals. They show they truly care by finding their loved one a new home. I commend those people. I mean the heartless people who abandon their dog in the cold or at a high kill shelter knowing that if there isn't any room their dog will be the first to be PTS. It's disgusting.
And that's why the more I know the more I'm convinced to rescuer future animals.
