SACRAMENTO (CBS13) — An Orangevale woman scoured her neighborhood for more than a week, searching for the dogs that brutally killed her Chihuahua during a walk in the park.

Kathilynn Carpenter posted fliers day after day in and around the park urging anyone to come forward who recognized the two German Shepherds that killed her Chihuahua.

“And they really just killed Mocha instantly,” said Kathilynn.

Kathilynn says her six-year-old Chihuahua Mocha drowned in his own blood; a quick death after an attack by two German Shepherds running loose in a Citrus Heights park.

“These dogs came to kill, they came across the park to kill,” said Kathilynn.

Kathilynn says she saw the dogs running towards her out of the corner of her eye, and she says she tried to run into the bathroom with her own three dogs, but it was too late.

“My dog is dead, you killed my dog,” Kathilynn says sadly.

And as she stood over Mocha’s lifeless body, she claims the woman with the German Shepherds finally got control of her dogs and promised she would be right back, but she never returned.

“My precious Mocha was brutally killed,” Kathilynn tells CBS13.

The dog owner worked daily to track down Mocha’s killers and followed a trail of leads, which lead her to a Citrus Heights home.

The German Shepherds owners didn’t want to comment, but animal control says they answered to their officers.

After a history of complaints against the dogs, they agreed to surrender the pair to the county.

Also, Kathilynn’s Great Danes, Sampson and Delilah, were also hurt in the attack, and are still healing from their wounds.

“He has a big gash and bite marks,” explains Kathilynn.

But, she is comforted that her detective work brought justice for Mocha, and although the killers were put down Thursday afternoon, their deaths, Kathilynn says, don’t compare to Mocha’s.

“At least it’ll be humane, you know, for them,” said Kathilynn.

Kathilynn told CBS13 that she usually carries pepper spray on walks, but that night she’d forgotten it.

Animal Control also says it’s up to Kathilynn to pursue any charges against the dog owner.
