My six year old Golden Retriever, Bianca, has now become an adoptive mother :)
Had the choice of three whelps, one white and two more golden in colour.
I picked the golden whelps, and watched their behaviour around Bianca (I took her with me to chose a puppy)
Bianca is a barker when stressed, and she is easily stressed around whelps, but has never ever attacked anyone.
So, as she barks, one of the whelps runs away in terror, while the other one, Balder, stays and he even barks back at her.
So, that is how i chose Balder <3
