How do I measure my dog for a crate?

Measure your dog from the tip of their nose to the base of their tail (not including the tail). Add 4 inches to this measurement — that's the minimum crate length you need.

Should I buy a bigger crate for a puppy?

Yes — buy a crate for their expected adult size and use a divider to section off extra space. Too much room encourages puppies to use one corner as a bathroom.

The 4-Inch Rule

The crate should be your dog's body length plus 4 inches — enough to stand without ducking and turn around. If you're crate training a puppy, buy a crate for their adult size and use a divider to block off extra space (too much space encourages them to use one corner as a bathroom).
