There is a huge difference between a dog that could stand to lose a few lbs and a dog who just needs more exercise with no change in diet.

You're dog could use more exercise with no change in diet if you're looking for a more muscular dog. Making your dog lose weight will not make her more "in shape" or more "muscular" it will only make her skinnier judging by how she looks now because she is NOT fat, just isn't "muscular".
