I recently acquired a 10 month old dog that will go out for a romp or walk and then pees/poops in her kennel. She has plenty of chances to go outside but seems to think the crate or kennel is the place to go. How do I undo this?

So for a dog like this there would be no romping or play or recreational walks until AFTER they pee and poop.

She would be treated like an 8 week old puppy that isn't potty trained. Since she has no issue with using the crate/kennel as a bathroom you have a big job ahead of you.

I teach my puppies from day one that going outside means bathroom break and we don't ever go out for walks, play or training until after they have relieved themselves. I figure out their patterns of when they typically need to poop (how long after meals) and if necessary I keep a chart so I can see the pattern.

Retraining dogs that don't seem to have issue with soiling the crate/kennel is a lot of work and you should plan on taking her out every hour or maybe even more often so you get success. I would also teach her to relieve herself on a leash or long line so you can monitor closely.
