Dennis, Many animals habitat are outdoors but these are DOMESTICATED breeds. There is a huge difference. Have you ever watched studies on how different dogs and wolves ( their ancestors) react? One example was that a wold never looks to a human to solve a dilema for them but the dogs always did. Their genetics are different.
Animals for sure! They are innocent, loyal, loving, and don't deserve to be left on the streets. People have abandoned them and they suffer at our hands, while many of the homeless caused their own dilema, not all ( the economy and some legitimate reasons have placed people on the streets ), but these domesticated animals are dependent on us.
