The reasons why Teddy always licks his urethra:

1. In estrus. When a dog is in estrus, it will also secrete fluid, and the dog will lick it frequently to feel comfortable.

2. Urinary tract inflammation. It may be that the dog has a urethra infection. The itching and pain will cause the dog to constantly lick its urethral opening to relieve itching and pain relief.

3. Clean after defecation. Many dogs who love cleanliness like to clean and lick their urethra after excretion in order to keep the urethra clean.

4. Sterilization and sterilization. If the dog smells some odor or leaks some dirty things, he licks them clean with his tongue and acts as a disinfectant.

5. Older. As dogs age, their body functions deteriorate and they may be unable to control their bowels and bladder. Dogs may also choose to lick their urethra frequently for comfort.
