The dog is never really bad; they are just reflecting the behavior of their owner. The feeling is very irritating when a dog jumps on you and puts paw prints over everything you’re wearing. Your yard is often a favorite place to use as a toilet. You call them bad dogs but are they? Not really because they only as bad as some of the poorly-brought up kids of the neighborhood. Can you expect pets or kids to behave themselves when the adults in the house are not behaving responsibly?
