If loading on a particular bone increases, the bone will remodel itself over time to become stronger to resist that sort of loading. The internal architecture of the trabeculae undergoes adaptive changes, followed by secondary changes to the external cortical portion of the bone, perhaps becoming thicker as a result. The converse is true as well: if the loading on a bone decreases, the bone will become weaker due to turnover, it is less metabolically costly to maintain and there is no stimulus for continued remodeling that is required to maintain bone mass.
So through the act of training and weight training on your bones ”should” be increasing their density, however I think the thing to consider here is “healthy person or animal”. As you stated you have seen a doctor about this and they “don’t know” what the issue is, if there is in fact an issue with BMD I would theorize that there is an underlying issue causing this.
