Not all dogs have black lips. I've seen pink lips, brown lips, even
dark blue lips. Lip color varies by breed.

To prevent sunburn.   Most of a dog is covered in hair & protects from
sunburn.   The nose & lips are mostly hairless and are usually black
due to higher levels of melanin.   Some dogs have pink lips and a few
have pink noses because humans have bred them for particular traits
for centuries, skewing the evolutionary advantage of particular
characteristics away from what would be natural.
