My sister just called and just put icing on the cake when she told me my dog is way too skinny.."she's anorexic". She's 19 months old and weighs around 62 lbs. I hear it a lot, but then I also hear GSD people say not to worry she'll grow into it. Should I be worried? I like her shape I don't she her ribs but you can feel them when you pet her. Please let me know what you think. I got her from the rescue so I have no idea what her family looks like.
