Not just the breeders that keep them in cages that makes me mad. But, I think it should be against the law to keep a dog tied to a tree, or run, all day. If you don't have time to spend time with something you said you would take care of for life, then, it's no different than child abuse. Don't get me wrong, I value a child more then a dog, but there is still a big responsibility you ought to feel.
When you adopt a pet, you are it's provider. It can't take care of itself for very long without being shot; and never, tied up 24-7. It pisses me off everytime I drive past some lowlife trailer trash and see a poor old pup tied or chained to a tree. Or worst, out in the sun.
