There is obviously an irritation. Puppy could be in pain, infection, abscess, nails could be growing into skin. This is a situation for a vet. Hope you can get your baby to the vet soon
Need to see a vet and soon. There can be many causes to this condition. There is also a chance of infection from the wound. 14th Street Animal clinic in Plano does walk-ins on on Saturday 9am to 11 or 12.
That's may be a vet question my dog licks his but to clean them
