Red Yeast Infection in Dogs

Does Your White Dog Have a Red Yeast Infection? (Mine Does.)

That's right, lil North is less than his typically bright self. Before you go around thinking he's a dirty dog — he's very clean thankyouverymuch — a red yeast infection is a common ailment of white or light-colored dogs, even though you may not know the disease by this name.

The bacteria Ptyrosporin, aka red yeast, thrives on moist, damp fur and causes reddish or brown stains below the inside corners of his eyes. And, since it thrives in wet spots, Ptyrosporin may cause the infection and staining, but it's my pup's excessive tearing that makes it worse.

At North's checkup, the doc determined that something in California is triggering his allergic reaction (since it was all clear in NYC) which causes his reddish marks and excess tears. He then licks his paws, another affected area, which exacerbates the situation there with more moisture. Eeks.

While he doesn't need antibiotics to clear this up, I've gotta keep a closer eye on his eyes to make sure it doesn't get any worse. Now that I've explained what a red yeast infection is, have you ever seen this in your pets?

I am very interested in your vets comment that this condition is being seen in California. I am an Immunologist and find this interesting from an epidemiological point. I have two mini schnauzers that both have developed a rust-red stain around their mouth, beard and paws. They have also developed very bad teeth.When living on the east coast I did not hear much about this issue & I personally never had the problem in my dogs.. In our area in Southern California there has been a significant increase in the number of reports regarding allergic dogs and interestingly, people. Please consult your vet and send me their business email which I will do in return. I think there could be a much bigger problem developing here than a problematic red color in fur.

Cornelius gets this often, too. I just make sure I clean his eyes every other day.

That is the cutest picture of North! My Bo-Ter, Monte, hopes he feels better.

Our frenchie gets this too. It was really bad when he was younger, but it has actually improved a little as he's gotten older. We usually try to wipe down his face once daily with an unscented baby wipe and then put a dab of desitin cream over the stain to help dry it out and block moisture.
