Maddie is my Catahoula Leopard, a pup I rescued from the shelter in my home town. It was love at first sight, and still is, but I discovered Maddie has a problem. She hates other dogs. I mean hates to the deathly extent. She will not tolerate another dog in her territory. I think it's genetic and I've diagnosed it as Antisocial Personality Disorder, but only in regard to dogs. She loves humans to the degree that she is the world's worst watch dog. She invites strangers to come in and regularly jumps onto the mailman's, UPS, and FedEx trucks when they come to deliver packages.
