Axel looks lovely and slim, and he looks fit. Yes, dogs come in all shapes and sizes - but I think a Labrador should be a medium sized dog, not a large one. That doesn't mean I think there is anything 'wrong' with those that are small (Betsy is small and I still think she is just lovely ) or large, but I personally think the UK (rather than the US which has been extended upwards in height and weight and has some very undesirable characteristics specified) breed standard is the 'right' size for Labradors. Don't get me wrong, of course lots of lovely dogs will fall outside this range, and that's fine - I don't think though that it is desirable to deliberate breed a range of dogs much smaller or larger. I also worry a bit when I hear people say 'he's going to be a monster!' like there is something good about that. Sometimes (like Axel) you just see a tall, but slim Lab, and that's just the way he is, and that's fine. But too often, you see a Lab that really should be a great deal slimmer.
