sounds like a brother and brother love. My inlaws had a white pommie named Zak. He always wanted to herd thembunnies we had. He had to be put to sleep because he had a massivetumor on his legs and it wrapped around its legs. Then it went ot hisheart and brain. Once it got to his brain he was not Zak anymore he wasa mean Zak so they decided to do that because it was best for him. I got a question for ya about Tinker. Is Tinker a barker. I know that Zak was a major barker where it peirces your ears.
