Use replacement car door seal. This is black and is therefore especially suitable as canine lips. Alternatively, use strips of leather. However, lips are usually omitted. The reason for this is simple. Assume that fur near a mouth lays downward, like a moustashe. The top lip will be partially covered with fur. If it is fully covered then it can be safely omitted. If it is partially covered, a more floofy coat can be simulated by a lack of top lip. Having only a bottom lip would look odd and so this is also omitted.
So, it is easy to create fursuit lips. However, having fursuit lips is uncommon. Not having fursuit lips gives the impression of a more luxurious pelt. Having two upper fangs is sufficient detail inside a fursuit mouth.
