Go Go My Walkin' Pup from Furreal Friends was white and approximately 12 inches long. The pup came when you called her and she had a realistic movement. I remember my Go Go My Walking Pup having really soft fur and a collar or bandana around the neck.
Made by Hasbro Go Go My Walkin' Pup was part of their electronic animals range. Other Furreal Friends in the range included a puppy, cat, kitten and My Little Lost Pup. Go Go My Walking Pup was cited as one of the most lifelike toy puppies at the time. Her head with move from side to side as she walked and her tail would also wag enthusiastically.
You could teach Go Go My Walkin' Pup a number of tricks including "Stay", "Guard Dog" and "Circle Parade" and she would even walk towards you if you called her by name.
