Do you know, I think its just that Campbell's can be spirited nippy little swines
my Campbell, Twilight, is off a breeder, and she's a feisty, but bite-y little thing, who won't hesitate to sink her teeth into you! In fact, she's very appropriately named, as she's like a little vampire, loves the taste of human flesh and blood
No amount of handling has changed her, shes fine once shes out (mostly), but just nips randomly at other times, sometimes softly, sometimes much harder. I have no idea why a breeder hamster should be like this, as the winter white I got off the same breeder is the most placed dwarf I've ever known, so laid back he's almost horizontal! So, I've come to the conclusion its just how they are, and thinking about it, most of the pet shop dwarves that I've had that have resembled Campbells have also had the same fiery temperament, and a bite first ask later philosophy
