I have a lionhead mix and I totally believe you. Some mornings I wake up and her mane is tame and small- other mornings I look at her and I'm like "um, where did all that mess come from?" and her mane will be sticking up all kinds of ways, longer and or thicker. It is relatively tame in my profile picture but lately its been getting longer and longer and longer. Sometimes I can give her a crazy comb over and mohawk other times that isn't even an option. The manes are fun- I am glad she isnt full lionhead because she hates being brushed and they require a lot of grooming. Just make sure to run a brush through her mane, that will help get some extra loose stuff off!
