Why Does My Dogs Wiener Come Out

Why Does My Dog’s Wiener Come Out?

It is common for dog owners to notice that their dog’s wiener, or penis, comes out of the sheath at times. This occurrence can be concerning, especially for pet parents who are not familiar with the anatomy and behaviors of male dogs. However, it is important to understand that this is a normal and natural occurrence in dogs. Here’s why it happens:

1. Erection: Just like humans, dogs can experience erections. This can happen due to various reasons, including excitement, sexual arousal, or even during sleep. When a dog’s penis becomes erect, it naturally extends out of the sheath.

2. Urination: Dogs have a unique feature called the “bulbus glandis” that helps them control their urine flow. This gland swells during urination, causing the penis to protrude. It is a normal part of the urinary process.

3. Cleaning: Male dogs may occasionally retract their penis from the sheath to clean it. This is a natural behavior to maintain hygiene.

4. Temperature regulation: Dogs regulate their body temperature through their genitals. In hot weather, the penis may extend out of the sheath to cool down and dissipate heat.

5. Hormonal changes: Hormonal fluctuations can cause changes in a dog’s anatomy. During mating or when exposed to a female in heat, a male dog’s penis may come out as a result of hormonal stimulation.

6. Medical conditions: In some cases, dogs may have medical conditions that cause the penis to stay out of the sheath for extended periods. This can be due to inflammation, infection, or a condition called paraphimosis. If you notice persistent or concerning behaviors, it is best to consult a veterinarian.

7. Individual variation: Just like humans, dogs can have individual variations in their anatomy and behaviors. Some dogs may have a more prominent or sensitive penis that may protrude more frequently.


1. Is it normal for my dog’s penis to come out?
Yes, it is normal for a dog’s penis to extend out of the sheath during certain situations, such as arousal, urination, or cleaning.

2. Should I be concerned if my dog’s penis stays out for a long time?
If your dog’s penis remains outside the sheath for an extended period or there are signs of discomfort, it is best to consult a veterinarian to rule out any underlying medical conditions.

3. Can I push the penis back into the sheath?
It is not recommended to manually push the penis back into the sheath, as it may cause injury or discomfort. Allow the dog to retract it naturally.

4. Will neutering my dog prevent his penis from coming out?
Neutering can help reduce sexual behaviors and decrease the frequency of penis protrusion, but it may not eliminate it entirely.

5. Can excessive licking cause the penis to come out?
Excessive licking can sometimes irritate the penis and lead to its protrusion. If this behavior persists, consult a veterinarian to rule out any underlying issues.

6. Can female dogs experience a similar phenomenon?
No, female dogs do not have a penis and therefore do not experience the same protrusion.

7. When should I be concerned and seek veterinary attention?
If you notice persistent or concerning behaviors, such as prolonged protrusion, signs of discomfort, or any other abnormal symptoms, it is advisable to consult a veterinarian for a proper evaluation.
