I am no vet but you might want to go to a professional veterinarian to get it checked out. Sorry about your dog as well!
Ok thank yoy for your comment. I've been spraying on her paws a product called The Traveler wounds and sores spray in the meanwhile till I can take her to the vet on Saturday
Could be from many things. Did you check out her paw for anything stuck in her paw? Maybe a cut? Stickers? Maybe something she's allergic to is irritating her feet. Has you're Yard veen sprayed with anything new? Used any new cleaning supplies on your floors or rugs?? You're doing the right thing by making sure that she's got a veterinarian appointment for Saturday, but if there's any way you can get her in sooner it would be best. Try washing her paw, and check for injuries or any foreign objects that could be causing her problem.
Yes, better see a veterinarian
