#1 Running away from home. No, dogs and cats are not rebellious teenagers, but they are explorers and with doors opening and closing so frequently they can easily escape unnoticed. During parties keep them confined to a quiet room, make sure they are microchipped. Never leave a collar on a dog or cat at home as they could get tangled up and accidentally strangulate themselves. Another option is a breakaway collar or harnesses which you can attach a small GPS too.
