I was in Seattle and had the pleasure of watching four mixed breed chihuahuas in a families home. The dogs all had completely different personalities; Luna was a weirdo she wanted attention only when she wanted it also having special needs, Milo was a quiet one but if you were ignoring him he made sure you listened, Dino was the pack leader (he owned me) and Mimi she was a complete spaz, very friendly dogs. I took them out of the house for walks, took them out hiking to a waterfall and just enjoyed their odd personalities over all. When it was time to leave I had a hard time letting go of such amazing dogs! Those owners are lucky to have them as pets. I've taken care of dogs my whole life, big and small, while always trying to have fun with them.
