Dogs will always lick, but it is sometimes embarrassing when they lick their private parts. Licking after eliminating is normal; however, if your dog licks more frequently, or you notice other signs such as discharge; swollen or red penis, vulva, or anus; pustules; discoloration of the skin; or if your dog strains to urinate, see your veterinarian for help. Appropriate medical therapy can reduce your dog's discomfort.
