I grew up with dogs; from puppies to senior dogs. I understand not all dogs have the same personality. I understand that every person has different views on their personal companions. Dogs unfortunately do not live as long as us humans, why not let your four legged family member decide who he/she likes? I have a theory on if my own dogs don't like someone, I become very wary of that same person. I've either owned / played with / or watched over almost most breeds of dogs through friends or family. I'm usually able to stop dogs from jumping. Learning how to sit, stay, shake (the basic commands).
