They both look really lovely

I think it's probably safe to assume that they are both WW/Campbell's hybrids, I can't say for sure about Switzerland but I don't think pet shops in any country sell pure bred WW or Campbell's , hybrids can look like either species so there's no way to know for sure.
They make the most adorable pets whichever species so other than being aware of them being prone to diabetes it really doesn't make any difference from a pet owners point of view.
