Was Meat Packed With Poison Left For Dogs In This Seattle Park?

Photographs and reports of suspected poisoned meat on the ground of one Seattle park has some scared that a malicious person is deliberately trying to kill local dogs.

Seattle dog owners Alison and Kyle Barker were walking their golden retriever in Carkeek Park on Saturday morning when they pulled a piece of meat from his mouth, reports local news outlet KOMO-TV. They didn't think anything of it until another couple showed them some photographs they'd snapped of meat chunks packed with unidentified aquamarine-colored pellets.

One of the photos the Barkers were shown Saturday morning in Carkeek Park.

The Barkers immediately took their 2-year-old dog, Berdy, to Seattle's Green Lake Animal Hospital, where veterinarian Jeb Mortimer told The Huffington Post he discovered aquamarine-colored pellets in Berdy's stomach after inducing the pup to vomit. Mortimer said the pellets were sent to a lab for testing. He believes they may have been rat poison.

"The aquamarine color is pretty classic for rodenticides," he said on the phone Monday morning.

Speaking to KOMO-TV, Mortimer suggested that the meat may have deliberately been left for dogs to consume.

"I think this intent is malicious," Mortimer said. "Someone's trying to kill dogs in my opinion."

Although Mortimer told HuffPost that Berdy was not showing signs of sickness when he arrived at the animal hospital, he said some exterminator poisons don't take effect for weeks.

"Some rodenticides cause leading disorders weeks down the road," he said, adding that the clinic is monitoring Berdy's blood values closely and supplementing him with Vitamin K, which a rat poison would have manipulated.

The good news is that Berdy seems to be recovering. Alison Barker said in a Facebook post that Berdy "is doing well so far, enjoying some snuggle time on the couch."

The Seattle Parks Department did not return a request for comment.

Dog owners in Seattle should call their vet or the Pet Poison Helpline immediately (800-213-6680) if they notice their dog eating suspicious pellets or exhibiting signs of illness.
