Hi W/C, welcome to the Forum! :)
Pads can take quite a long time to heal, 2 or 3 weeks isn't unknown :( Paw injuries are a real nuisance, because the dog should be kept to lead walking on smooth ground until it has healed. Pads are very difficult to stitch; sometimes vets use Superglue to hold the flaps of flesh together, and feet are awful bandaged, because you
must keep them dry or they get infected within hours.
If you can keep it dry it will heal, but it won't be quick. Sorry.
