I won't have a dog. They are generally expensive to keep. They only last a few years. They generally get bored and destroy things if you allow them indoors. They require exercise and attention.

Here in Greece, the local farmers each keep at least one dog tied to a tree to scare away predators. It gets fed food scraps when available, and water, when they remember. A barrel is provided for shelter if there's no tree. The orthodox church teaches that dogs don't have souls so it's OK to treat them like dirt.

I'm not condoning this; just explaining the attitude.
