Teen Mom 3's Mackenzie Douthit just welcomed the newest member of her rapidly growing family, y'all! No, Mackenzie didn't pop out her baby daughter (though we expect that blessed event to go down in a few months), but she did get a new puppy with her husband, Josh McKee, and we can't even deal with its cuteness.

"Me and josh just have a growing family ;)" Mackenzie posted to Instagram along with a picture of herself snuggling her pup. "Meet our new son. I'm so in love."

Ditto, girl. Although, we were under the impression that Teen Moms were contractually obligated to own French Bulldogs, and it looks like Mackenzie and Josh's new addition is a sweet little (er, big) boxer! We're sure Mackenzie already has her hands full taking care of this bruiser, and we can't even imagine how she's going to juggle doggie-duty with mommy-duty once she welcomes a newborn baby into the fold. Plus, let's not forget that Mackenzie already takes care of her son, Gannon, 24/7 –– not to mention the OG boxer puppy she bought back in July!

Are you surprised that Mackenzie and Josh got a dog considering that they're about to have a baby? Seems like more responsibility than they might be able to handle … weigh in below and tell us what you think!
