So glad i came across this, my dog has a small patch like this in almost the same spot. I thought it was a callous, i gotta take him to the vet. Thanks for this.

These are impacted follicles caused by the dog sleeping/laying on a hard surface. The skin will thicken into a callus. A common problem.

Poor little dog, that’s abuse, why mistreat him like that. That is torture.

This is a stolen video, the dog has a skin condition which causes blackheads on his elbows, the guy removes the blackheads every month
Why would he have so many blackheads? Fake!Source: ViacomCBS Inc.
