My dog had penile surgery & castration. Why isn't he peeing or pooping?

He should be rechecked by your vet or at the local veterinary ER today. He may be painful or still feeling the aftereffects of general anesthesia. This can last as long as 72 hours. If his bladder is full, the doctors can insert a urinary catheter if necessary to empty it. Medications can be administered or dispensed to alleviate pain which may make him comfortable. Supportive care can also be administered. SQ fluids may rehydrate him and perk him up.

Pain after neutering does occur, and your vet can give you pain medication for him if they haven't already. After neutering, some dogs can be tired and want to rest a little more than usual. Keep an eye on the stitches where the surgery was done, and make sure they don't become red and swollen. Do not let your dog lick the stitches. Your dog likely didn't poop until this morning because they weren't allowed any food for 12 hours before the surgery, so they wouldn't have anything to poop out. Butt scooting can also indicate parasites, so if his worming isn't up to date, I would get worming tablets from your vet. If the incision site becomes red, swollen, and warm to the touch, I would contact your vet right away for an appointment. It is also okay to give your vet a call if you are concerned about your dog being in pain, and see what options they can give you for pain relief.

It sounds like your vet did all the right things. You could do a urine culture as a double check for an infection (although that would be very uncommon in an adult male dog). I would be starting to get concerned about a tumor within the penis or possibly a neuromuscular issue preventing normal urine flow. If your vet is out of ideas (as I am), the next step would be going to a specialist, probably an internist.

This can happen. Between being fasted prior to surgery and pain medications, his GI system may be empty yet or slow. Continue to feed him as you normally and he will eventually defecate. If he doesn't within 48 hours of eating normal meals, have him rechecked by your veterinarian.

Hi. Poor ginger. Sometimes patients won't defecate for a couple days post surgery. But, if she is actually struggling to go, she may be constipated. If it is continuous struggling I would go to ER. If it's just been a couple times, i would do all you can to get her to drink water, add water to her food. Hopefully that will help. Go to ER if she is in pain

Given that Stanley was recently neutered and had abdominal surgery to find the undescended testicle, he may be a little painful still and that's causing him to cry out in pain when pooping. It could be as well that if he is on pain medication, it is making him a little constipated, and you can try adding a tablespoon of canned pumpkin puree (not pumpkin pie filling) in with his food to see if that helps. If this doesn't help, and he's still crying when pooping after 24-48 hours, then I would take him into the vet for an exam.

You need to feed him something high in fiber for the next couple days and also make sure he is taking in enough water. He probably has some dehydration that is causing him not to poop. High fiber foods can be bread, cooked squash or pumpkin, high fiber cereals (if he will eat it). You can also give him some chicken or beef broth to drink - the high salt will make him drink more water. Hope this helps.
