My dog, Sadie, will be a year this Friday (Happy Birthday). She has her favorite toy - a stuffed bear that sings "Rock-a-Bye-Baby." She is completely obsessed with it. She won't go anywhere without it, nor sleep without it. She actually carries it around and then licks it clean and gets mad when you take it away. Is this her motherly instinct coming out? Does anyone elses dog pretend their toys are their babies?
