Although he may look thin, skinny, starved, or whatever the case may be, that dog, in that picture is in optimal shape and condition. In that picture, he was eating no less than 7-8 cups of premium dog food per day rather than 3-4 cups if he was just being fed to stay at a healthy state. You will not see many dogs as well conditioned as he is in that picture, whether you or anyone else thinks he is too thin or not. There is little to no back bone showing, no hip bones showing, and no matter what anyone thinks, only a hint of ribs showing in that picture... in that picture, he was not thin, skinny, starved, neglected, or abused, but simply worked.
Can you further explain this comment?
