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

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | unneutered | 3 years and 2 months old | 28 lbs

My dog just had a penile amputation surgery and got castrated at the same time yesterday. He had trouble urinating (came out drop by drop) due to the penile infection and no bowl movement for 3 days before the surgery. The vet says he should have started doing both already after surgery. Any ideas what I can do to help him? Food? What are the signs of it becoming an emergency?

If the area is too swollen for him to urinate (ie the urine cannot be evacuated through the opening prepared by the surgery), then this needs to be rechecked by your veterinarian. He could also withhold urinating due to pain, so make sure you give him the pain medication given to you for him by the vet , or get some from the vet for a few days. Any movement, including pressing to poop, probably hurts, so Ginger may try to avoid eliminating. Again, pain medicine is necessary to help him eliminate without fear and pain. Food wise, I suggest you feed him the food he is used to, do not abruptly changed his diet. If Ginger does not urinate within another 23 hrs, it is an emergency and he must be seen by the vet.
