 Say someone relinquishes a dog to a shelter because they say this dog nipped their baby. Now that shelter worker says to a potential adopter, hey, this dog's a baby biter. You know that dog's never going to be adopted. If I heard this, my first thought would be, why is this dog, any dog, allowed to be in close proximity to a baby? What happened? Who's the owner? And where was the owner? Perhaps this dog is not a good fit for this particular family with a baby.
