A perineal hernia occurs when the muscles of the pelvic floor (the perineum) weaken or separate, allowing abdominal contents—such as fat, the rectum, or even the bladder—to bulge into the area surrounding the anus. This condition is most commonly seen in intact, middle-aged to older male dogs.
Perineal hernias typically develop slowly. If you notice any of the following, your pet should be evaluated by a veterinarian:
This is the gold standard technique. We carefully reposition a nearby muscle (the internal obturator) to "bridge the gap" and create a strong new pelvic floor.
Since hormones play a significant role in the weakening of these muscles, we perform a castration (neutering) at the same time as the repair to drastically reduce the risk of recurrence.

Recovery is a collaborative effort between our clinical team and you at home. Most patients enjoy a high success rate with proper aftercare.

I am so grateful to Northwest Referrals for operating on my dog who had IVDD of the neck for 10 weeks and was in a lot of pain.
We have been seen the next day, CT scan confirmed slipped disc already suspected after quick examination. Surgery was the same day, he has been recovering amazingly quick and well, his cut healed perfectly and we cannot thank all the team enough!
I honestly cannot rate this referral centre highly enough!
Had an MRI for my chihuahua. Results came back quickly. The vet was professional, and all the staff was very nice to us. The price was reasonable as well.
It’s always going to be expensive when it comes to being referred by your own vet. The great thing about Northwest Referrals is the costs are all up front.
If I could give 20 stars I would. I spoke to Amanda who was super helpful and gathered as much info as she could after speaking to the vets/surgeons.
We travelled from Birmingham… The bill was exactly what we had been quoted.
Not only were they a third cheaper, our assigned vet was professional and explained everything in detail.
