Is a second hernia surgery safe for my 11-year-old dog this year?

First of all inguinal hernia and umbilical hernia are two different things, completely unrelated. it's absolutely safe to have another surgery done 6 months after the first surgery, this surgery is really a must do.

If a hernia is repaired surgically, there is always a small chance that it will herniate again at some point of time in the life of the dog, obviously more care needs to be taken up to 10 days after the surgery to prevent from the wound and sutures to open.

Thanks for visiting Petco Pet Education Center, formerly Petcoach! I do see one little scabby area at the lower part of the incision, but otherwise it appears closed and healing well. Just to be on the safe side I would recommend waiting a full another 4-5 days before bathing to allow the scab to fall off. Continue to monitor this area for any discharge or separation of the skin. Also that swelling on the left side should be evaluated by your vet if it doesn’t resolve, just to make sure it isn’t another hernia. Mild suture reactions just below the skin can also cause swelling, which is usually firm and doesn’t depress when pushing down on it. I hope this helps and best wishes with your pet Aspen. Take care.

Perineal surgery is extremely difficult due to the abnormal/stretched anatomy and narrow safety margins to avoid major nerves and blood vessels. As the muscles and nerves have been stretched and displaced, normal outline and normal healing is unpredictable and outcomes are not certain. Infection of the surgical site is a significant risk also and many patients which develop hernias also have additional complicating factors with regards to anesthetic safety also. Recovery is slow, painful and often incomplete and such a surgery should never be undertaken lightly. I am sure your vet would have considered all possible risks and outcomes in assessing his case

It is ok for Lily to remain on those antacids long term. I suspect there are reasons your vet considers the surgery to be risky (brachycephalic breed, senior age, complicated nature of the surgery, possible bloodwork issues). It is great that they have stopped the vomiting. Putting her on an intestinal diet that is easy of the GI tract such as Hills i/d dry and canned or Royal Canin GI dry and canned may help as well. Good luck!

I have to say i disagree with your vet. both hernias should have been operated on when he was younger. he isn't young but isn't very old either, my advise would be to do the surgery to repair the inguinal hernia.

Yes, it is important to have surgery done on this because if left untreated, it can be serious. A loop of intestine can become entrapped in this hernia, which will make the dog very sick. Puchku should have this fixed, and I would have it done when you have him neutered (if he isn't already neutered). Because umbilical hernias are hereditary, dogs with them should never be bred. Best of luck.
