Maybe it's the same cuts and she keeps re-opening them? It could be from ice or grit just now, is she doing a lot of fast turns and skidding? I would try not to let Mika lick the cuts, Tilly had stitches in the back of her ear once when she cut it open on some scrap metal and Alfie kept licking the wound and it got horribly infected, the vet had a huge go at me for letting him lick at it

Do you have any styptic powder? It's good for stopping bleeding and is antiseptic, if not then antiseptic spray or cream should do the same job.
What are the stopper pads?
It's the pad at the back of the foot right at the bottom of the foreleg, if you feel around the back of the wrist joint it's there.
