Pigtails or french braids combine two things that dogs love: something to chew and something to pull. If you see a dog who is looking at you like you're a piece of meat, for one you should watch out because that dog might eat you, and for two, you should check if you're wearing pigtails or braids. If so, hide them into Princess Leia buns. If not you might end up playing tug of war with your own hair.
When they are puppies it is so cute to have your dog chew on your hair. It feel like a little ticklish massage. Then they grow up and they're cracking your neck with one quick snap of their head. It's a habit you better break when they are small and cute. Once we have puppies that stay puppies forever, we won't have to worry about that anymore.
