Remi has had these crusty, brown-ish "bumps" appear, get bigger and then dry and flake off two different times now. They are about his head and neck area. Does anyone have any knowledge on what they could be? I have had dogs all my life and have never seen this before. It's almost as if it oozes and dries and they get bigger and then crust off. He doesn't itch them and when I touch them, he knows they are there and just lets me know not to pick at them, but doesn't act like they hurt. One possibility I thought was maybe while wrestling with his Boxer brother or Poo sister, maybe they pinch him with their teeth and it irritates his skin? I will have him to the vet to have it checked out soon. I know it's nothing contagious as none of my other four ever have this.
