I say dips her back because her back does not normally appear to be bowed or arched, as in how she stands, walks, and runs. Her behaviors throughout the day generally seem to indicate her back is not bothering her. However, often, although not always, she will dip her back when any pressure is place onto her lower back. Things like people simple stroking her, when approaching her back, she will dip her butt towards the ground, very similar to how she does when she pees. She doesn't yelp or itch or anything. I've asked the vet, and they didn't have any particular concerns but I feel like they weren't seeing the problem at the right perspective. Does that make sense? I don't believe they really looked past the fact that she's a little skinny, both pointing that out. That is a potential cause, I'm aware of this, but I don't feel like that's the problem. It can't be due to insignificant nutrition as a puppy because I've always packed top of the line food into her (fromms,Stella and chewys, Origen). She's always been extremely active, so much so I've had small Thoughts of possibly too much. Any ideas or daily tips that may help? A lot of Touch stimulation is my current idea.

It sounds like she is probably just sensitive and dips away, but without seeing it is hard to say. Can you put a dog backpack on her (If you have one or can borrow one) and see if she will sit down under the weight of it or if she will stand normal? It could also just be a habit. If you touch my girl's butt above her tail she will automatically sit. Something that became habit apparently when she was being taught to sit.
