It's against forum rules to attempt to diagnose something that hasn't been seen by a vet in order to protect you from bad advice that might hurt your pup or delay necessary medical treatment, so I'm afraid we can't guess at what this might be.
What I would do is contact your vet clinic - and others in your area if necessary - asking if you can send them this picture so they can help you decide how urgent this is. If it's something that should be biopsied and examined at a diagnostic lab as soon as possible, they'll get you in for an emergency appointment, and if they believe it's unlikely to be anything scary/malignant, you'll have better peace of mind waiting until they open to non-emergency appointments again.
