The Chattanooga Times Free Press reports Bradley County sheriff's deputies called the Society for the Prevention of Cruelty to Animals of Bradley County on Wednesday to help seize the animals because there were so many.
Deputies who answered a call at the home about a verbal domestic situation discovered the animals.
"Once deputies addressed the domestic situation, two detectives arrived to investigate concerns regarding the animals," said Bob Gault, spokesman for the Bradley County Sheriff's Office.
Bobbi Anderson, director of the Bradley County SPCA shelter, said the owner surrendered most of the animals to the organization.
"She knows she needs help," Anderson said.
SPCA volunteer Ashley Crittenden told WRCB-TV that there were 237 dogs in an outbuilding and 12 in the house. Most were beagles.
"(I saw) dog after dog, puppy after puppy in just horrible conditions," she told the Times Free Press. "I mean five or six dogs in one kennel, and there's no telling how long it's been (since) these dogs have been cleaned. It's horrible."
Anderson said all the animals need to be examined and vaccinated.
"The beagles will not be made immediately available for adoption," SPCA media director Beth Foster said in a statement. "We are working with rescues around the country to find them safe places."
Gault says no charges have been filed, but the investigation continues.
