I haven't noticed that where I live, but it does take a while for US trends to reach the southern hemisphere. Most of my pets have had human names: only four dogs haven't: Bingo and Bonzo, and Whuskers and Wuffles. A spaniel was
Sheena, but that was because our other dogs (B and B, W and W) had been Scotties and Westies and her fur was so glossy compared to theirs. Our current cat was named Pixie at the rescue centre, so we stayed with it.
