but that shouldn't be the only factor. Weight is basically just a number...you need to look at the whole dog (and I'm talking about an adult dog, two years or older); younger than 2yrs they can still be maturing and altho the weight may not change much or at all, the "shape" of the dog may. With some genetic lines, the dogs don't fully mature until 2 or 2.5yrs meaning that the skull may widen, the chest deepen and the expression on the face changes gently as well...a more matured look...and sometimes the ears relax more (excitable youngsters sometimes carry their ears or tails 'high').
To decide what a good weight for your dog is, look at the parents, look at the height, look at the width of the front legs, look at the width of the neck, look at the skull, and look at the 'length' of the back. A dog that is 'heavy-boned' will have thickness in leg and neck, rounded paws with wide toes, and so some of the weight may appear to be 'hidden' inside. A taller, more slender dog can weight the same number of pounds and look quite different.
My comments are not meant to be a value judgment, for we all know that the sweetness inside is what really matters for our beloved pets!
