I agree, she does look good weight but if you feel she NEEDS a few more pounds, feed her your brand of puppy chow. Our dog Zoey Mo was such a scrawny thing we thought she was sick or something, other people though we didn't feed her (She ate her bowl and our other dogs at times). As it turns out she got just a veracious metabolism and works off regular food super quick, so we switched her to puppy chow (vet recommended). She finally had got a few pounds on her now and looks a lot better
Feel free to message me any questions, I'll try to help the best I can!
