Your vet is the best person to tell you if your dog is too thin. Generally speaking, you want to be able to easily feel the dogs rib cage and have a layer of fat over it. You should not be able to see the ribs, however. It's hard to tell from the picture, but she looks pretty good to me. I have never had fat dogs, in fact, mine are a little on the thinner side, but that's healthier than a fat dog. Remember she's a pup, she can burn off more calories than an adult dog so if you feel she needs more food and she isn't getting fat I think you have some wiggle room.
