Your friend could be right. Let her run and walk on natural surfaces like grass, dirt is best. If not, concrete paveways, tar roads, badminton courts, basketball courts etc..also can do. Hopefully this can correct back the front paws. I have been told that if the doggie is kept indoors too much, walking mostly on smooth surfaces like our marble, tiles or parquet floors can also contribute to this condition. However, this east-west paws condition may also be genetically based. Not too sure on this. Will have to check it up later.
