Mimicking Behavior

You've seen those people who look like their dogs or their spouses, well I don't look like B or James. Yet somehow, B has developed some of my oddities that are completely unexplainable. I understand when I'm upset that B becomes upset or depressed or excited. He's just mimicking my behavior, but things have become really strange recently. To begin with, I am an overly anxious person and B comes from a breed that suffers separation anxiety. When I went in for surgery, they damaged an unrelated organ resulting in further issues. So it shouldn't have been a surprise when B went in for surgery in January and I received a call at the midpoint that there were some extra problems discovered and they needed permission to extend his surgery. I have several anomalies where the doctor commented one in so many people have this or one in so many chance this will happen. Guaranteed, it will happen to me. Apparently, B falls into this same category. He had a tumor removed during his surgery in January. There was 5% chance of a regrowth of the tumor. Now, until he sees the vet, I'm unsure if it is another tumor or an infection, but either way, there is an anomaly. So, B does take after his human owner in a variety of ways.
