I've had a dog for close to a year (can't seem to figure his mix, though chiwauwau is definitely one). Every time I see him he rolls on his back for me to pet him, which I always do. It makes him feel great. I work 5am-1pm, but have ample amount of time to tend to any dog's needs after that. Each dog I see I want it to be my dog at home so I can play with it and rub/scratch it and just make it feel good. I also have an empathetic and sympathetic aura that some dogs I think can sense and I feel that'll allow me to establish a good rapport with all pets and animals. I also feel that I can learn a lot from different animals, how one likes to receive treatment over another, which is parallel to how people feel as well. It's good to know your population.
