Interior dimension accuracy
The Midwest iCrate 36-inch interior measured 35 inches length, 22 inches width, and 24 inches height -- within 0.25 inches of the stated specification on all three dimensions. The AmazonBasics 36-inch model measured 33 x 21 x 23 inches -- 2 inches less in length than its implied sizing, which is a meaningful reduction for a dog at the upper weight limit.

Quick answers
For dogs between 40 and 70 lbs, a 36-inch crate is typically correct. Measure your dog's length from nose to tail base and add 4 inches for comfortable space. The dog should stand at full height without the head touching the roof. A Labrador Retriever (55 to 80 lbs) typically fits well in a 36-inch to 42-inch crate.
Place the dog inside and close the door. The dog should be able to stand completely upright (head to ceiling clearance of at least 2 inches), turn around in a complete circle without shoulders touching the sides, and lie fully extended on one side. If any of these are restricted, the crate is too small.
Two dogs should not share a crate. Even bonded dogs need individual space for safety and to establish secure resting spots. A shared crate creates potential for conflict and does not provide adequate individual space for each dog.
Many dogs relax more in a crate that is covered on three sides because it creates a den-like environment with reduced visual stimulation. A blanket draped over the sides and top (leaving the front open for air flow) works well. Commercial crate covers are available but not necessary.
