Armadillos are fast. A good practice wild animal. Raccoons? They are another story. Watch for poop sneaking. This dog we have now used to try to secret them into the house by holding them gently in her mouth (so she would not crush them). Luckily she also wears her feelings on her face (poop face is guilt) so I could turn her around, shove her out the door and demand she drop it. So disgusting. Glad she doesn't do that anymore. Now, just lizards. Same face.
