NAPLES, Fla - A Collier County woman is looking for answers after her dog is mauled to death by another dog off-leash.

Naples Police and Domestic Animal Services are both investigating the deadly attack and looking to the public for help in tracking down this dangerous dog.

Mary Klum and her husband adopted a Chihuahua Shitzu mix a few months ago. "We just fell in love with him right away," says Klum. They named him Woodstock after the bird in Charlie Brown. Their four legged friend instantly became a part of the family, but just as quickly tragedy struck. Her husband was walking Woodstock on a leash near a pond when a dog came out of nowhere.

"He came through the bushes and grabbed Woodstock and started shaking him and biting him," says Klum. "He had multiple wounds, his liver, kidneys, his heart were all punctured."

They took Woodstock to the emergency hospital, but he didn't make it. "It's been horrible for my husband and I," says Klum. "I guess closure will come, but I don't know when."

The Klum's filed a report with Domestic Animal Services. The report says a neighbor saw the dangerous dog jump into a red vehicle with a blonde haired woman, but neither have been seen since.

"We'll chase down any lead we have, unfortunately we don't have too much to go on," says Amanda Townsend, Director of Collier County Domestic Animal Servics.

Now, a local animal rescue, Brooke's Legacy is getting involved. The Klum's adopted Woodstock from owner Tink Bechtol. When she heard the news, she was determined to help find the owner of the missing dog. "Whether you're a parent of a child or a pet owner you have to have responsibility."

According to DAS there were 4,942 calls for stray animals in Collier County in 2012. In 2011 there were 5,162. While the calls are for cats and dogs, they're primarily dogs.

While the dangerous dog wasn't a stray, it gives a sense of the number of dogs roaming around without leashes. Collier County has a strict leash law that says pets must be confined to the owner's property or walked on a leash and pets may not run at large.

Mary doesn't want the missing dog put down. She just wants its owner to come forward so her pain is not repeated. "If it happened once it can happen again and that's what scares me," says Klum.

The dog is described as a brown, short haired, mixed breed about 50-70 pounds. Anyone with information is asked to call Domestic Animal Services at (239) 252-7387.
