    This photo shows just how bad Asia's hair loss (alopecia) got over the winter. She lost virtually all the hair on the lower half of her body. Though it is faint here, she also has some red patches on her skin. Her condition improved a bit in the spring, growing some of her hair back.

    Asia's supposed histiocytoma is shown in this photo. About three weeks after it appeared, it started to clear-up. It was a relief to see it shrink away, as a surgical removal became unnecessary.

    Dog Skin Allergies

    This photo shows the rash that Simba would typically develop when his skin problems flared up. You might also notice that one of his nipples is enlarged from being chronically irritated as that is an area where he scratches a lot. The sores became much worse over the summer of this same year.
