[Lightning&Stomps]

I just noticed that Lightning has dark crusty stuff in his armpits. He's never had inflamed armpits like a lot of dogs on this forum. He also developed lip fold pyoderma in the last 6 months or so. He's never had that before either. He's about 12. Before Stomps died, at 13-15 years old, he developed a horrible hot spot where his jowls met his neck. So as dogs age do they become more prone to such things? Could this be secondary to a more serious problem? Other than a little arthritis, he seems fine. Good weight, good appetite (a little too good), nice coat, good attitude. But I worry...

Yeast on the skin is omnipressent it is always there. It is kept in check by the immune system.imune system function is lowers as the dog age so it is logical that the are more prone as the age but I did not find any study investigating this.
