What is the average weight of a Border Collie? 30-40 lbs for a female (13.5-18 kg) and 40-60 lbs for a male (18-27 kg) Though there will always be exceptions to this (i.e. larger or smaller dogs), the large majority of Border Collies fall into this range. The breed as a whole is a medium-sized breed.
Collies are a larger breed with males standing 24 â 26â at the shoulder and females being 22 â 24â. This means that they compete in agility classes against Border Collies, Golden Retrievers, German Shepherds, Dobermans etc. In order to be competitive in official agility events, a Collie needs to be in good weight, in good athletic condition, and have a desire to work with and for its handler.
