It sounds to me like your niece is jealous of the time you give to your fur baby. She may have had a bad day, and was afraid you were to involved to pay attention to her. People that don't have this deep bond with a dog don't realize it works both ways. We get the same devotion and love from them that we give to them. If loving and caring for a little creature that relies on you for its very life is weird, I wish more of us were weird. There is no where that I have more fun than with my sawyer. I go other places, because my husband, children and grandchildren share my life too; but if I were to be completely honest, the most fun I have and the times I feel most complete are the times I spend with sawyer. So, you are not weird, just complete.
