Why does my dog have irritated skin and yellow penis discharge?

Updated On September 23rd, 2025

Pet's info: Dog | Siberian Husky | Male | 10 months and 22 days old | 50 lbs

What could this be? He is 1 year old in a month. I am taking him to the vet in a week but wanted an opinion anyway. He had fleas but they are now be treated. I switched his dog food to simply nourish in hopes it was just a flea allergy. I have noticed yellow fluid come out of his penis once (about 2 days ago) but it hasn't happened since. I have happy jack mange medicine but not sure if it will work. Will it?

I am not really sure what it could be. This is not the normal presentation for mange mites, but it is still possible. Other causes are trauma from rubbing or scratching, bacterial infection, yeast infection, ringworm, allergies, autoimmune, among a few other things. I would not treat for mites right now. Instead, I would just continue to watch it and point it out to your vet next week. If it gets suddenly worse or appears to be spreading quickly, you may want to move up your appointment. The yellow discharge is likely smegma. This is completely normal in male dogs, but is more common in dogs that have not been neutered. It is not a concern unless it seems to bother Echo or you see him licking frequently. https://www.chelseadogs.com/blog/smegma-101/
