Brothers from Another Mother

On Drake and Josh they called each other my "brother from another mother". Today, I was doing an inspection and was talking to the owner and out of the corner of my eye I saw a dog lying outside. I stopped, moved over and stared. Then I asked if this dog was a Rottweiller/Lab mix. She said he was and that he was nine years old. He is just like our dog, Bear. We compared notes and they have the same temperment and idiosyncracies. Wonder if this is Bear's "bother from another mother?"

Poor Max lost his mate a while back and continues to be very sad.
