What is dog photophobia?
Photosensitive dogs squirm in apparent discomfort when exposed to light. They scratch or rub lightly pigmented, exposed areas of skin (for example, the ears, eyelids, or muzzle). Bright sunlight can cause typical skin changes, even in black-coated animals. Redness develops rapidly and is soon followed by swelling.

There are two types of UV light with slightly different wavelengths – UVA and UVB. UVA is absent at sunrise, then relatively stronger during mid-morning and late afternoon.
