I was just told that that last dog was not Rex, but Mandy, a dog I posted about in September 2006. Mandy and Rex looked so much alike they could have been siblings, though I don't think they were brought in together. The facts are true about Rex, however.
This pedigree commercial was filmed here at the Carson shelter. Rex is the last dog in this commercial, cocking his head.
Sadly, Rex remained unadopted and over time became mentally unhinged and started aggressing at some of the staff and volunteers who had been taking care of him. The shelter reluctantly ended up having to put him down.
It's very unfortunate, but the reality is that there are too many of us who need homes and not enough people willing or able to adopt us. It certainly doesn't help that condominium homeowner associations put in place strict rules about adopting larger dogs.
