Rebecca, that should be no problem at all. There are undoubtedly going to be skin cells and all sorts of other stuff in *all* the samples. The instructions are really just to distinguish this from other collection kits where the goal is to get skin cells. These kits get the best DNA from saliva itself, not the dead skin cells – so the goal is to soak up saliva.
We’ve used these kits well on small pups:
