What is this on Ddog’s mouth?

[JenandFlo]

Ddog has had what looks like scar tissue on side of her mouth for about a year. Showed vet who wasn’t concerned.

Today she has a cut/sore just above scar tissue that look a bit weepy. I’m reluctant to go to vets at the mo, but will take her if necessary.

Would be so grateful for advice.

Is it only on the outside of the mouth ( doesn't go right through )? How long has it been like this ?

Sorry , saw it was year. That'll teach me to read properly!

Honestly, I would take her back. It is a long time and if it nothing , great. At least you know.

Could you sent photographs to the vet?
I hope it's nothing serious.

I took her to the vets and they thought it was a bite that she has scratched. Am so relieved as thoughts of Alabama Rot were going through my head.

Thanks so much for your advice.
