Kim Zolciak-Biermann and Kroy Biermann want dog owners to know the signs to look out for if their pets are being aggressive.
The couple, who have been married since 2011, faced the nightmare of their lives on April 22, when their dog Sinn bit their 5-year-old son Kash, nearly blinding him.
“It was a like a bad dream,” Kim, 39, tells PEOPLE exclusively of the bite, which left Kash in the hospital for 4 days, the scratch a millimeter away from his eye. “Our dog Sinn is heavily, heavily trained. Kash is his favorite. It made absolutely no sense to any of us. This is nothing I ever thought I’d be dealing with in my life.”
Though Kim shared news about the bite on social media after it happened, much of the details surrounding the incident have been unknown until now — including the fact that Sinn was the one who bit Kash. The two were playing outside alongside the Biermanns’ other son KJ, 6, when Kroy was using a leaf blower to clean the yard.
“Sinn doesn’t like the blower, so he’s already in high alert,” Kroy, 32, says on Friday’s episode of Don’t Be Tardy, which documents the aftermath of Sinn’s bite. “My back was to the dogs and the boys. I hear Kash be loud, and then I hear barking. And then I hear Kash screaming, he’s crying very loud. At that point I think he’s scared, but then I realize Sinn bit Kash. He’s dripping blood everywhere on his shirt. He pulls his hands down and there’s multiple lacerations, I can’t see his eye. I knew it was a very dire emergency.”
Looking back on it to PEOPLE, Kroy says he’s still coming to terms with what happened. “It’s a process every day,” Kroy explains. “Being right there, it was just wrong place, wrong time, wrong circumstances. The perfect storm. Had one thing been different, it wouldn’t have happened. You try to say, ‘What would I have done differently?’ And there are a lot of things. now, but you can’t change any of it. You just have to learn from it and grow from it.”
“There are no words to describe something like this,” Kroy continues. “I just pray that any parent out there does not have to go through anything traumatic like it. It’s just a horrible feeling to have to go through.”
As Kash was taken to the hospital, Sinn’s trainer immediately came to the Biermann house and removed the dog from the home while Kim and Kroy — who have six kids total and four other rescue dogs — decided what to do.
The decision to keep Sinn didn’t come easy. The Biermanns had rescued Sinn, husky-boxer mix, as a puppy three years earlier. Kroy’s instinct was to get rid him now.
“I hated Sinn,” Kroy says. “I genuinely felt a deep rage for what he had done to my son. Sinn was always a good dog, extremely obedient and protective and not at all aggressive. He’s hyper-active and hyper-sensitive but wants to work and loves to be commanded. I love my dog, and nothing like this had ever happened to me before. But it’s my son. I don’t love anything more than my flesh and blood. I thought, ‘I don’t want to see the dog — he doesn’t get a second chance.’ ”

Complicating matters was the fact that over the years, Sinn had formed an “incredible bond” with Kash. “Sinn and Kash have been best friends since the day we got Sinn,” Kim says. “Kash is an absolute animal lover, and Sinn is definitely his favorite, without a shadow of a doubt. That’s why it was extra hard.”
“I genuinely felt a deep rage for what Sinn had done to my son, but Kash loves him,” Kroy adds.” We didn’t want him to live a life with a phobia of dogs. We wanted him to understand it wasn’t his fault.”
Speaking with nearly a dozen behavioral specialists, child psychologists and dog-bite survivors, Kim and Kroy spent a lot of time evaluating Kash’s moods and anxiety level after the attack. The boy — who the Biermanns describe as “super strong and positive” — appeared unfazed, even asking to see Sinn while he was in the hospital.
“He saw a service dog in the hospital and he hopped up out of the bed. He was all over the dog, petting the dog and loving on the dog and kissing the dog with no inhibitions,” Kim remembers. “It was unbelievable.”
“If Kash ever looked at me and said that he didn’t want to be around Sinn or showed any hesitation, then he wouldn’t be here,” Kim stresses. “We love Sinn, he’s part of our family, but our children will always come first without a doubt.”
Seven months and multiple surgeries later, Kash is healthy and 95 percent healed — even getting a puppy for his birthday in August. And after an eight-week break, Sinn was slowly welcomed back into the home, with some very big changes.
The dog’s crate has also been moved out of the home’s high-traffic area to give Sinn some sanctuary. He occasionally wears a muzzle, too.
Still, the biggest change has been that Kim and Kroy now know what to look out for — and hope that viewers learn from their nightmare.
“We’ve taught our kids, no matter how nice dogs are, they are capable of anything and cannot communicate to us in another way than through action — be it barking, growling, biting, scratching, or running away,” Kroy says. “A child sees flurry, fluffy, fun, slobbery … they don’t see danger. And we didn’t either, as adults who had always owned dogs but never gone through something like this. But you have to understand those triggers. Whether it’s loud noise, their tail being pulled, whatever it is, it should be on the forefront of everybody’s mind. Not as fear, but just awareness.”
All and all, the Biermanns are grateful for all the support they received from family and friends, especially Children’s Healthcare of Atlanta, Dr. Jerry E Berland at Thomas Eye Group, Chief of Plastic Surgery at CHOA Dr. Joseph K Williams and Gabe Reinlieb at Tenacity Dog Training. “I honestly don’t know what we would of done without them,” Kim says.
