My dog licks his private parts a lot and he has some red marks where he licks. What should I do while I go to my local vet? And what may it be?

Chestnut could have inflammation or some kind of irritant in his prepuce (the skin that covers the penis) that is causing discomfort. He could also have a urinary issue or allergies. I'd recommend preventing him from licking as much as possible if the skin appears red - you may need to purchase an e-collar for him to wear when he's unsupervised. Your vet can examine the area and might recommend checking a urine sample.
