My unneutered dog has red discharge from his penis. Is it serious?

Updated On September 23rd, 2025

Pet's info: Dog | Yorkshire Terrier | Male | unneutered | 5 years and 11 months old | 7 lbs

Hi, prince occasionally has puss coming out of his penis, it's sometimes red inside his penis and sometimes it's pink, but he has puss that's like right there at the tip and I'm assuming it comes out when he is urinating. Should I be concerned?

Since Prince is not neutered, it is very common for unneutered male dogs to have a small volume of yellow/green discharge at the tip of the penis. However, if this discharge is reddish it makes me concerned he may have an irritated penis or a urinary issue like a bladder infection. It would be wise, if this continues, to have him examined by a vet. He/she will want to take a urine sample and test if for inflammatory cells and potentially do a bladder ultrasound or X-ray.
