How long does it take for dogs balls to shrink after neutering? - The Environmental Literacy Council (2025)

The question of how long it takes for a dog’s scrotum to shrink after neutering is a common one among pet owners. The simple answer is that there’s no one-size-fits-all timeline. While the testicles themselves are removed during the neutering procedure, the scrotum remains. Post-surgery, the scrotum’s appearance can vary quite a bit, and the shrinking process is gradual. Typically, the initial swelling seen right after the procedure will begin to subside within 10-14 days. However, the full shrinkage, where the scrotum becomes a small, loose flap of skin, can take anywhere from a few weeks to several months. The exact timeframe depends on factors such as the dog’s age, breed, and individual healing rate.

Understanding the Post-Neuter Scrotum

Initial Swelling vs. Shrinkage

Immediately after neutering, it’s normal for the scrotum to appear swollen. This is due to the body’s natural inflammatory response to surgery. It might even look like the testicles are still present. This initial swelling usually peaks within the first 24-48 hours and then starts to decrease. Do not be alarmed if it looks larger initially; this is a typical part of the healing process.

As the swelling goes down, the scrotum will begin to contract. If the dog was neutered as a puppy, or while still immature, the empty scrotum tends to flatten out as the dog continues to grow and mature. However, in mature dogs, the empty scrotum typically remains as a small, loose flap of skin.

Individual Variation

The rate at which the scrotum shrinks varies greatly from one dog to another. Some dogs may experience a significant decrease in size within a few weeks, while for others, it may take several months to reach its final, shrunken state. This is perfectly normal, and there is no reason to be concerned unless there are signs of infection or excessive swelling.

Factors influencing the shrinkage rate include:

• Age at Neutering: Younger dogs may experience faster shrinkage as their bodies are still developing.
• Breed: Different breeds may have varying tissue elasticity.
• Individual Healing Rate: Each dog’s body reacts differently to surgery, impacting the healing process.
• Weight: Overweight dogs may have more tissue, potentially making the scrotum appear more prominent.

What to Expect During the Recovery Period

First Few Days

The first few days post-neutering are crucial for monitoring your dog’s recovery. Expect the scrotum to be swollen, and there might be some bruising. Your dog may also experience some discomfort, which is why veterinarians prescribe pain medication. Be sure to follow all post-operative instructions provided by your vet to ensure a smooth recovery. Limit your dog’s activity to prevent complications and allow the surgical site to heal.

10-14 Days Post-Surgery

By 10-14 days, you should observe a decrease in the initial swelling. The incision site should also be healing, with the edges coming together. If the swelling persists beyond this period or if you notice any signs of infection (such as excessive redness, discharge, or heat), it’s crucial to contact your vet immediately for a recheck.

Long-Term Changes

Over the following weeks and months, the scrotum will continue to shrink, eventually reaching its final size. As mentioned, in mature dogs, this usually means it will become a loose flap of skin. This process is gradual, and full shrinkage can take several months. It is essential to be patient and allow your dog’s body to heal naturally.

Frequently Asked Questions (FAQs)

1. Why are my dog’s balls still big after neutering?

Initial swelling is a normal part of the healing process after neutering. This swelling can make it seem like the testicles are still present. The swelling typically subsides within 10-14 days. If the swelling persists beyond this, consult your vet.

2. Will my dog’s empty sack shrink after neutering?

Yes, the scrotum will shrink over time. The time it takes varies, but it will typically become a small, loose flap of skin. Younger dogs may see their scrotums flatten more as they grow.

3. How long does it take for a dog to get back to normal after neutering?

Most dogs recover quickly from neutering. They’re usually back to themselves within five to seven days.

4. How long does it take for a male dog to settle down after being neutered?

You might not see behavioral changes immediately. It can take about a month before you observe any shifts in your dog’s behavior due to neutering.

5. Will my dog’s balls shrink after neutering?

Yes, the testicles are removed during neutering. What you’re seeing post-surgery is the scrotum, which will shrink over time.

6. Does a male dog’s personality change after neutering?

Neutering often leads to a decrease in behaviors like aggression and territorial marking. Your dog may also become more affectionate and easier to train, but their core personality will not drastically change.

7. Are male dogs more affectionate after neutering?

Many owners report that their dogs become more affectionate after neutering, alongside less urine marking, less fighting, and a calmer demeanor.

8. How do I know if my dog is healing properly after neutering?

Check the incision site daily. You should notice the edges coming together within the first week. Mild oozing or bruising is normal, but excessive swelling or discharge needs veterinary attention.

9. Do dogs get more attached after neutering?

Neutering can lead to a desire to stay closer to home, reduced fighting with other animals, and increased affection.

10. Can a neutered dog still lock with a female?

Yes, neutered dogs can still “lock” with a female, as the neutering procedure only removes the testicles. However, they cannot impregnate a female.

11. Why do my dog’s balls look deflated after neutering?

The deflated look is normal and often due to a reduction in post-operative swelling. The scrotum will eventually shrink further and become less noticeable.

12. What do vets do with dog balls after neutering?

Testicles are considered anatomical waste and are typically removed by a professional disposal company and incinerated.

13. Why does my neutered dog look like he has balls again?

This is due to the remaining scrotal sac. Post-operative inflammation can make it look enlarged initially, but it will shrink as the dog heals.

14. Why do dogs cry after being neutered?

Crying or whining after surgery can be due to a combination of anxiety, discomfort, and the effects of anesthesia.

15. Does neutering a dog reduce anxiety?

While neutering can help with some behavior issues, it may not reduce anxiety and could potentially magnify anxious tendencies in some dogs.
