I disagree. The very first greyhound I met, who is now part of our local play group, is a 95lb dog. He doesn't look his weight. He has lots of muscle, and is fit and healthy looking. Not the faintest bit overweight. He is a large greyhound, and when I first met him after he was brought here from the track, he was definitely underweight. He weighed around 78lbs. Maybe he's an exception, and certainly there are greys that need to lose weight - it's never good for dogs to be overweight anyway, least of all greys as it can bring about all sorts of health issues. However, to call many of the dogs I've seen fresh off the track "fit", is laughable. There is a difference between fit and underweight, and many of the greys I've seen when they're first brought over from the track are severely underweight. The fact that they are kept that way to make them faster is motivated by money, not health reasons.
