Actually just saying weight is not important takes that part of the standard out of context. There is much more to that To sum up, Yes the UKC standard lists the desired weights and after that goes into talking about that the weight and also the height are both less important than the dog having correct proportions. Dogs above the listed weights are not penalized in the show ring unless they are rangy or massive which would make them out of proportion here is a link to the UKC standard http://www.apbtconformation.com/ukcstandard.htm They can't pass a dog off that has crappy proportions... at least not to as judge that knows the breed and goes by the standard
