Real Housewives of Atlanta star Kim Zolciak went through one of every mother’s worst nightmares this weekend after her 4-year old son Kash Biermann was attacked by a dog.

“I don’t know where to start,” she wrote on Instagram. “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. The last 14hrs of our lives has been a living nightmare.”

I don’t know where to start. The last 14hrs of our lives has been a living nightmare. 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. 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 ❤️

It’s unclear what breed or type of dog attacked poor Kash, but because of the situation, Kim won’t be attending this Sunday’s Watch What Happens Live where she was previously scheduled to be.

“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,” she added. “A very special thank you to my incredible medical team! A few days in the hospital and we will be back home.”

Our thoughts are with you Kash.
