Many times, fungal infections have a kind of sour, yeasty smell, or just makes your one dog
smell like about 10 dirty dogs
! Meds and medicated shampoo can clear that up. I have one dog who gets doggy athlete's foot - fungus. She has really thick toe pads with lots of hair, so moisture tends to hang around in her feet, and dogs have sweat glands in their feet too. Once the fungus gets going, it irritates the skin, so she licks contantly.
