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.

Xanthine bladder stones are an uncommon type of urinary stone that can occur in both dogs and cats. Xanthine is produced when purines (a component of animal proteins) are broken down within the body. Most dogs can further break down xanthine into other substances that are easily excreted, but some dogs are deficient in an enzyme that is required for this breakdown to occur. These dogs develop elevated levels of xanthine in the urine, resulting in xanthine stones forming within the urinary tract. They can also form secondary to administration of a medication called Allopurinol. Xanthine urinary tract stones are typically removed surgically. Affected dogs require long-term care with specialized diets to prevent recurrence.

Zinc-responsive dermatosis in dogs is a skin condition that results from zinc deficiency in the body. The deficiency can be due to an inability to adequately absorb zinc from the diet, zinc binders in dietary supplements, excess calcium (juvenile large breeds) or less commonly, an inadequate amount of zinc in the diet. Signs and treatment are discussed.
