Kim Zolciak, Kroy Biermann, Cops Called for Dog After Allegedly Almost Attacking Kid

9:39 AM PT -- A source close to Kim Zolciak says the police never spoke to Kim and Kroy Biermann after the report was made, and the reporting person allegedly doesn't even live in the neighborhood.

Kim Zolciak and Kroy Biermann are in the doghouse with law enforcement yet again ... after some pissed-off neighbors called the cops after one of the estranged couple's dogs nearly attacked a kid.

Alpharetta, GA cops got a call last week about the Biermann dog from a woman who said it was off its leash ... the woman claimed this wasn't the first problem with the dog.

The caller told dispatch the dog "almost attacked her kids" last month, telling officers the pooch chased them -- but thankfully, no one was injured.

Given what allegedly went down, the caller said seeing the dog roaming without a leash was concerning, telling dispatch the dog is "super aggressive and never confined."

Kim and Kroy's dogs -- Stone and Sinn -- were apparently the topic of discussion in a Facebook group as well -- with a conversation posted on IG account @Thegoodthebadandthefake6 concerned parent saying a dog had tried to "tackle and attack" their kid, who was riding a scooter.

Folks chimed in, pointing the finger at the estranged couple and saying -- "It may be [Kim and Kroy's] dog. He is usually behind the gate in the front yard, but sometimes their driveway gate is open."

BTW, Sinn bit their son, Kash, back in 2017 ... nearly blinding him.

But the dogs are obviously not Kim and Kroy's only problems ... as we reported, local cops have been called a couple of times to their home, and body cam footage from August showed how unpleasant things have gotten in their house recently.
