I have unfinished post about Brut and Silver's "monogamy," and the curiosity if there is such a thing. I'm sure if Brut had the opportunity to mate with another female, he would have done it, but I find it unique that he never try to escape for it. He never roamed. He didn't have to, he had his girl right at home.
This "monogamy" that Brut and Silver carried out was so intense for Brut, I think it was the reason he died first. Hence, he would have never survived the loss of Silver. I had these feelings years before Brut died with what I witnessed between them. Since Brut was an aggressive dog and threw out his feelings instead of withdrawing the situation would have been worse than any dog fight that we've ever had. Obviously God must have had the same thoughts and we were blessed without knowing what would have happened if Brut hadn't of died first.
And like most couples who live together for years, when one goes, shortly afterwards the second one follows. Silver was no exception. After a year and a half without her boy, she followed Brut home. She had her time with just the kids, preparing them for their new roles they would undertake as the Alpha dogs of the Back Pack. While she prepared for heaven and her reunion with Brut.
