Investigators say they believe someone intentionally poisoned two dogs in the backyard of their owner's Haslet home.
Fort Worth detectives said they believe the bloodhounds were given food soaked in antifreeze.
The dogs' owner, Joan Britt said she saw Sadie and Simon devouring a bag of dog food she hadn't given them in her backyard on May 13, but didn't think anything of it.
“It looked like someone threw the bag over,” she said.
But 24 hours later, Simon, a 4-year-old show dog, and a puppy, Sadie, were having seizures and vomiting. Britt rushed the dogs to an emergency clinic.
“I was thinking, 'Please let them be safe. Don't let it be poison, but, you know, by that time, I knew it was something pretty bad," she said.
The vetrinarian found traces of antifreeze in both dogs' systems.
Britt made the heartbreaking decision to put both dogs down. She said she feels as if she has lost two children.
“I love my dogs," she said. "They are my family."
Fort Worth police said they have never received a complaint about a barking dog from Britt's address.
Investigators said they have not received any reports of other poisoned pets in the neighborhood.
“We have every reason to believe that this is an isolated incident,” Sgt. Chad Mahaffey said.
Mahaffey said investigators have a strong lead in the animal-cruelty case but have not made any arrests.
Britt is not taking chances with the safety of her three other dogs. She installed a fence in her backyard and plans to add surveillance cameras around her house.
“I’ve got to protect what’s left," she said.
