Border Collie puppy: what to buy, and what size
A Border Collie usually suits a 36in crate, but they are leggy: check height as well as length, because a young collie can hit the roof of a crate that is nominally the right size. They are bred to work, and a bored collie finds its own job. Chewing is often the first one it picks.
Adult crate size: 36in — check the height too. Sizes are given against the adult dog, because that is what you should buy for.
