I've worked for Come, Sit, Stay, and for Hob Nob. Both jobs entitled me to overlook yards up to 20 dogs of all sizes and personality types. I've fed boarding fur children, and daycare, some with meals as easy as kibble, others with very strict 5 star instructions. I've done grooming services like bath and nail trims, for pets with wild, crazy, matted hair and those with short curly hair. Young and old! I believe that dogs are the closest to people, in the sense that they have fears, experience, happiness, and a very good judge of characters. It's an art actually, in my opinion. Reading a dog to determine what they're feeling is a very good trait, because there could be health reasons and safety measures that you'd need to see to be able to keep them at their best, and happiest. Along with that, once a puppy, always a puppy.
