My dog was neutered, but his sac looks like testicles. Is it normal?
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.
