My dog has a red spot on his knee. Is it an infection or contagious?

My dog has this red mark on his knee. Do you think it is an infection or just rug burn from playing or something? Should we be concerned about it being contagious to us? It doesnt seem to be bothering him, he is not scratching or licking it.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Riley. It could be from an injury. I would keep an eye on it for now. If it gets bigger, you see signs of infection, or it starts bothering him, then I would be concerned and have him seen by a vet. I hope this helps!
