Maci Bookout may still have several weeks to go before welcoming her little lady, but one member of the "Teen Mom OG" castmember's household is already cuddling up to her bun in the oven.

Bentley's fun-loving mama -- who will welcome daughter Jayde Carter with longtime boyfriend Taylor McKinney in June -- shared a heartwarming Instagram snapshot of her darling dog Bonnie resting comfortably on her third trimester bump. And by the looks of the delightful image, Bon -- who joined the clan this past Christmas -- is going to be an inseparable pal of J's in the not-so-distant future.

"Bonnie is patiently waiting on baby girl," the 23-year-old added along with the collage-style photo showcasing the adorable pup placing her pinch-worthy face on M's pink-clad belly. If canine's could talk, we're sure B would tell her owner that her tummy is very comfy for a snooze -- but would also stress that she'd like to have playtime with this precious peanut ASAP.

Speaking of being ready to give birth, Maci -- who is almost 33 weeks along -- made it crystal clear how she's feeling these days:

Hang in there, M!
