I agree... for the most part she looks pretty healthy... but she could stand to put on about/up to five lbs. (not really a huge issue. It is said that a dog will be healthier being underweight than overweight.)

I'd just suggest a better quality food if she's on a cheapo one, or if it's decent just adding aprox. 1/8 cup more per feeding. (I of course would just add a few more chunks of raw chicken )
