My dog is 1 year old Alaskan Malamute and she has the exact same symptoms. Only the vet gave me something to put directly on the sore and it didn't help. So I got her a head coller to see if that helps and she also looks at me to take the dang thing off.
The vet told me that when she licks the sore it becomes a bad habit, so I have to try to break the "Bad Habit". I resently discovered that if you give her a bath in warm water with baby shampoo and then after she air drys put baby powder all over her fur ( make sure you get the sore spot(s)) it seems to make the her feel better and not lick herself.
I have a 5 year old boxer named Chopper,lovely dog,but he licks and has Lickgranuloma,I took
dog to vet and he says sometimes when their thyroid
isn't putting out enough of whatever it puts out
they begin to lick,He gave me some thyroid pills and
that worked for awhile,but then he went back to licking,I now put an ointment on his paw called
resinol,when I put this on him,its a thick ointment
so it doesnt come off easily,and then I dress his
foot with a kids sock and then I tape this,and change
his dressing once a day in two days his sores were gone.
