I graduated from college 1 1/2 years ago. Last fall I decided to get a puppy, and after much searching I got Riley last April. I am currently living at home. As Riley is my dog I do everything with him. When I am home Riley will rarely respond (come, sit, etc) to anyone else and will instead run to me and hide behind or between my legs. When I am not home he is good for my mom, okay about 50% of the time for my sister and wont't listen to dad. Although Riley seems to be excited to see dad in the mornings and runs and jumps on him. Riley has never physically been punished and rarely yelled at. If he gets in trouble I use a stern voice and put him in his time out spot. Am I doing something wrong that Riley isn't more friendly/responsive with my dad and sister? Or is it their fault for not making more of an effort to be with him? I do take him places as often as I can to socialize him. Or could he just be more of a 1 person dog?
