She could just have an itchy back like humans can get. The best thing to do is take a look. Take a brush or comb and brush hair in the opposite direction. If you see dandruff then your dogs skin is very dry and the best thing you can do is bath your dog with an oatmeal based dog shampoo (use it on my own dogs.) It could also be flea season in your area and I was quite surprised when my vet told me (I live in British Columbia, Canada) that fleas have a high resistance now and can strike pets at any time of the year ... even in the cold months of the year. If your dog is still scratching (they should be brushed every day) then take her to the vets as she may have a form of dermatitis. I have a Bishon Frise' that can have ear problems (inflamed) and I smell them every day to be sure there is no odor. I clean her ears with a herbal liquid solution every week and I also check all my pets (on all parts of the body) for lumps or bumps once a week.

In the wild, a dog lives in a pack and will cover its poop. That is what a dog is doing when it kicks its legs after pooping, although it may not make as much of an effort at it when it is living with a human family. In the wild, the poop if left uncovered can lead predators to the dog.
Dogs kick their back legs when playing to show excitement and engage in playful behavior. This action is a natural instinct that mimics hunting behavior and can also be a way for dogs to release excess energy and communicate with other dogs.

no they will bite maybe but not scratch.
Dogs have 4 legs.

in a way. the back legs support the horse and boost him off the ground to run. So yes. If the horse did not have back legs he would not be able to run.
Dogs are aware of the presence of their back legs, as they use them for movement and balance. However, they may not have the same level of conscious awareness or self-recognition as humans do regarding their body parts.
