Query: Stopped working the day after christmas

the toy stopped working the properly the day after the christmas. I had brought it for my 2 year old daughter, but when she called it, it wouldn't come, walk, bark or do anything. We would be sleeping in the middle of the night and the dog would start barking, and walking by itself (the batteries were brand new, so there is no excuse. Needless to say we immediately returned it the store.
