Here is a pic of a normal dog paw and a Basenjis, even if your girl doesn't have pads like a Basenji it doesn't mean she hasn't got some Basenji in her.
When we had a Basenji i noticed Benjis pads were joined but at the time thought all dogs were like this. It was only later that i found out only Basenjis, possibly Huskies and wolves have these pads
ChowChow's have feet like that and it's really noticable in feet that big. I'll try to get a pic next time i'm around a chowchow foot.
