Alanis is picking up correct ADT habits. For her last outing each night, she makes a circuit of the chicken pen where I hope she pees all over the place. Somebody on my chicken list has a theory that dog pee helps keep raccoons away. Or maybe the pee is just good luck (it's got to be good for something).
Every night the neighborhood raccoon crosses my front yard to the back gate where she climbs my fence into the trees that border the yard. Instead of climbing down to the yard where the chickens sleep the sleep of the innocent in their coop, she walks along the wood fence or through the trees and goes down into a neighboring yard. Early in the fall, I even caught her and her two cubs on top of my house a couple of times.
Although Airedales are natural varmint hunters and raccoon scent is used in hunting trials, I'd never want one of my dogs anywhere near a raccoon. It's not fear of rabies; it's that a terrier will happily fight until it's in shreds and raccoons are vicious beasts. Sorry chickens, the dog comes first.
