While the consistency of crate location can be great for some dogs, it can also be a deterrent for others. If it's too near excessive noise, vents, or anything else that could cause a disturbance, they may still go in but enjoy it less than they might otherwise. Try their crate in a few different spots and see if they're any more satisfied in places other than where it currently rests.
Sometimes your dog needs a safe place to retire (or you need a break) but may still get bored. Give them an appropriate chewy and let them make their own fun in the confines of their crate.
If your dog already loves being in their crate, you don't have to rock the boat. But, if you happen to have more space, a change in space coming, or can finally afford something a little nicer, take them crate shopping to test a few out. Modern crates can be collapsible for easier travel, dual-doored for easier access in tighter spaces, or provide more support in general, so give them a nice upgrade if you're able to. It may just make them love their crate that much more.
