A dog (usually a small breed) that was owned by an old lady and was spoiled because she treated it like a baby. Old lady dogs tend to be very demanding of your attention, and will jump into your lap whenever you sit down. Quite often they hate males, but love females. Can be very sweet if broken of 'granchild-like' expectations. Do not get along well with other animals, and become jealous very easily. May be accustomed to riding in a stroller and being dressed up in cute outfits. They like to bounce and prance around like bunnies in order to get attention. Also, they'll intentionally shake to get your attention.
When my mother brought home another dog, I was surprised to find that he had been an old lady dog.
