here is a link for humans and what i want you to look at is nutritional aspect below so scroll down
Burns
some thing she may want to think about and ask vet are
COQ10
CALENDULA
COCONUT OIL as that is natural anti-bacterial and antifungal and can be given internally and many of us use this for skin in our dogs
fish diet as it has omegas in it like cod
so check out that as that may speed up the healing process but obviously discuss all this with the vet or specialist
