A Young Cavachon Suddenly Licking His Penis
by A reader
Sudden licking and sensitivity can come from irritation from a shampoo left on the skin, an infection of the sheath or penis, a urinary infection, or a small grass seed or debris inside the sheath. The darker look at the tip may be dried discharge or blood.
Until the appointment, rinse the area gently with lukewarm water or saline to remove any shampoo residue, pat it dry, and use a cone or a soft T-shirt to stop him licking. Don't apply creams unless your vet says they're safe.
Go sooner if he strains or cries when peeing, there's blood in the urine, or the swelling gets worse.
