If his sac looks like it has testicles in it, this is most likely due to swelling from the surgery. This is called a scrotal hematoma, and is fairly common after a [neuter surgery](https://www.petcoach.co/article/benefits-of-neutering-castrating-male-dogs-puppies). The swelling can definitely look like testicles, but it's just fluid and blood clots from the procedure. It should resolve on its own within the next 7-10 days as long as you [keep him calm and quiet](https://www.petcoach.co/article/6-ways-to-rest-your-pet-after-surgery-or-injury) and prevent him from licking at the surgical site by using an [Elizabethan collar (e-collar)](https://www.petcoach.co/article/e-collars-for-cats-dogs-types-of-collars-and-diy-options/). The testicles themselves are removed during the neuter, so they're definitely not still there. If you have any concerns about how it looks, you can always have him rechecked next week with the vet who did his surgery to make sure everything is healing as expected.

    The testicles have not grown back, I assure you. What you are seeing is a build-up of fluid/blood in the scrotum (seroma/hematoma). After the testicles were removed from the scrotum that left behind some empty space and often times fluid will fill it up. I suggest you do the following: 1. minimize his activity - any extra running/jumping/playing can make this worse 2. ice the scrtoum for 10 minutes 2-3 times per day 3. Keep an Ecollar (cone) on his head until this is resolved. If he licks this he will make it worse - it could get infected or he could open the incision up. If this looks no better in a few days you should get him to your vet for an exam. The other possibility is that he could have a herniation into the scrotum so be aware of that. This could be life threatening so if he acts ill in anyway you need to get him to your vet for an exam ASAP. Hope this helps. Best wishes.

    Hi. This is most likely a hematoma...bleeding into the scrotal sac. It can be a complication of surgery. This looks pretty inflammed. I would call your veterinarian and ask to come in. In the meantime, ice the area. If they cant get you in, ER

    Some minor swelling is normal, but if he is in discomfort or having difficulty walking or you notice any discharge from the wound you should have him rechecked by your vets office. Keep him confined to the lead but encourage gentle walking 10-15mins at a time
