Health Agency Warns of Werewolf Syndrome Caused by Dog Treats

An alert has been raised in the UK regarding a specific type of dog treat produced in China under the Barkoo brand name. The warning came out because this particular chew can turn your pup from a loving little critter into a dog that exhibits the aggressive traits of well, a werewolf… or even worse. Which makes this one an odd warning, but definitely not funny.


The urgent notice went out last week after a dog in the Netherlands reportedly died after eating the Barkoo treat. That, combined with several other incidents being reported to the country’s health agency is what caused officials to ring the alarm bell.


The after-effects of consuming the bone treat were fast and highly disturbing to consumers. These symptoms - along with how quickly the red flag was raised - immediately drew the attention of pet owners across Europe.


Known as Werewolf Syndrome, the dogs who had been given this tasty chew experienced a sudden behavior change that included epileptic seizures, panic attacks, howling, spasms, and aggression that one might associate with a wild animal. Hence the name.


While the product is not sold in the UK’s bricks-and-mortar style pet stores, the country’s health agency is concerned that it can be purchased online and imported for consumption. Now we’re talking worldwide because as we all know, accessing products is easy for any country that supports online shopping. And that’s what drove the urgency to warn pet owners on a global level. It was noted by UK health officials that there is no evidence these chews pose any risk to human health.


But here’s another concern. Because these chews have a long shelf life, it’s possible they may have been purchased months ago, tucked away for future enjoyment, and are now not recognized as the brand name that’s being red flagged. While the ingredient that causes such an intense response in dogs has not yet been identified, it’s a good idea to steer clear of the brand and/or dispose of any recent purchases from their facility. And if you’re like me and repack treats into airtight Ziplock-style bags – meaning you no longer have the branded packaging – you may want to consider pitching and repurchasing from a known supplier.


Not only are pet owners being warned to check their pup’s treats, but veterinarian clinics have also been advised of the situation and asked to watch for symptoms that might be connected to the consumption of these chews.
