I used an indoor dog pen like this: https://www.amazon.com/gp/product/B07GXMP19D/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Zip tied some 1 X 1 boards to the bottom for stability and structure, and put it over a large waterproof pad. If you buy a few extra pieces, you can make it larger. I found that stuffed toys that talk when you push on it kept her interest intermittently. I only left her alone for an hour at the most, but no barking. Good luck!
