How it works
Crate length is the dog's length from nose to the base of the tail, plus a few inches. Crate height is the dog's height at the top of the head or ears, plus a little more.
Use the crate's inside measurements, not the outside ones, because the walls take up room the dog needs.
Worked example
A dog 30 in long and 24 in tall needs a crate about 34 in long and 26 in high, measured inside.
Questions
Why measure inside?
Outside measurements include the walls, and that room is not space the dog can use.
How much extra room does this add?
This page adds about four inches to the length and two inches to the height. Many dogs are more comfortable with more room, so measure again if you are unsure.
Can a puppy use a divider?
Some owners use a divider to adjust the space as a puppy grows. Ask a trainer or your vet what suits your dog.
