Kim Zolciak-Biermann's 4-year-old son, Kash, was hospitalized over the weekend with serious injuries after he was bitten by a dog.

The former Real Housewives of Atlanta star was to set to appear on Watch What Happens Live With Andy Cohen on Sunday evening but had to cancel that appearance and took to Instagram to share the news about Kash with her followers.

"The last 14hrs of our lives has been a living nightmare," she posted alongside a picture of her husband, Kroy Biermann, holding Kash's hand as the little boy laid in a hospital bed. "My sweet @kashbiermann was bit by a dog and had very traumatic injuries. I've never prayed so hard, or been so scared in my life. My husband, our daughters, Kj, Tracey, his nanny, Michael Beck and everyone close to us all pulled together and held each other up.

"Kash was in the operating room for a couple hours and now we are praying for a quick speedy recovery," Zolciak continued. "Due to this I will not be on WWHL tonight but will do my best to make it up very soon! Thank you for all your prayers and most importantly Thank you God for your protection. A very special Thank you to my incredible medical team! A few days in the hospital and we will be back home."

On Monday, she posted another pic of Kash awake and alert in the hospital and announced that he was going to be discharged later in the day.

We're glad Kash is being released earlier than expected and wish him a quick recovery!
