Lastly, keeping weight off your dogs is another important factor to maintaining health and function. We all know that staying slim is healthier for everyone, but each unnecessary pound makes achy joints all the more painful. Adding 5 pounds of fat to Katie's frame may look more pleasing, hide those arthritic ribs, and fill in areas of muscle tone loss, but it would do nothing to aid her in staying strong.
Katie had a chest x-ray about 2.5 years ago and it was interesting to see the bony changes in her ribs. They are very pointed and jagged so they are more prominent than they used to be. The picture above was taken about 8 years ago when her sides were smoother. Happy Birthday, Katie!
