My baby Bella has a curved spine. I was wondering if this was normal or not. Then we got Luigi and his back is straight. I read a few weeks ago about Roachback and it is exactly what her back is like. Next time we go to the Vets I will ask him about it. She seems to walk and run fine and never seems to be in pain. It is just an arched look to her back. Hopefully. Here are some pics of Bella where you can see her arch.
