All dogs reached no higher than the knee, and weighed no more than 15 kilograms.
Six of the dogs were about a year old, with the other possibly being the mother of the group, according to The Daily Ardmoreite in Oklahoma. When first responders arrived on the scene, at least one of the dachshunds turned on them, too, even charging toward the rescuers.
County sheriff Chris Bryant said: "Unfortunately, yes, we had to shoot one dog".
Garcia was near her home when the dogs, who lived on a neighbouring property, attacked her on Thursday evening. The AP reports it's not clear what led to the attack.
Officials said six of the dogs were believed to be standard dachshund and terrier mix.
The animals were infested with fleas and ticks, but didn't have any other visible health issues. The dogs ranged in age from 1 to 3-years-old.
Dinwiddie said all the dogs had characteristics of a dachsund, such as their "knobby legs, knees, very short-legged dogs and their coats".
"The predominant breed in these dogs is definitely standard dachshund", Ardmore Animal Shelter's euthanasia technician Amanda Dinwiddie told local media.
"This is a bad situation, a very unfortunate situation", Bryant said.
The victim of a deadly dog attack in Carter County last week has been identified. "This is just a bad deal all the way around". "You can tell they have been living out in the woods".
The sheriff said he hopes to have the autopsy results and other relevant information ready for the district attorney's office by Tuesday morning. After reviewing the necessary documents, the District Attorney would decide whether to press charges against the pet owner.
Most recently, Garcia worked as a housekeeper at the Hilton Inn in Ardmore, Oklahoma, in order to support her family financially.
