Why is my old unneutered dog skinny with bloody penis discharge?

Updated On September 23rd, 2025

Pet's info: Dog | Labradoodle | Male | unneutered | 12 years and 11 months old

My dog is 13, he’s a uneutered male. He’s always been a thin dog, but he’s look extremely skinny now and is having a bloody discharge from his penis now. I took him to the vet a few weeks ago thinking it was his anal glands. Any help Is appreciated!

He needs a urine sample performed to check for an infection, crystals or cancer cells. An ultrasound can look inside the bladder to check the wall thickness and look for a mass and check his prostate . At his age any of these are possibilities and there is no way to know without testing
