Hi,
You'll need to stop her from licking her paw because it will only makes things worse.

Try some Bitter Apple spray or cream, which should be available at a local pet store.

I would definitely get your pet to the vet as soon as she gets back in town. If an infection has started, she may need antibiotics.

Good luck with your doggie!

thanks for the reply.. i've brought her to the vet already and the sore has actually healed even before the vet visit! all the vet did was picking off the scab.. =D
