In several European countries, severe neurological symptoms have been occurring in dogs for several months: whining, barking, sudden panic attacks and uncontrolled movements. In some cases, epileptic seizures also occur later. The reason for the so-called werewolf syndrome is probably toxins in certain chewing bones of cattle.
It cannot be ruled out that other products are also affected. It’s clear this is a European problem – and it’s here to stay, Nina Meyerhoff of the Hanover University of Veterinary Medicine explained on Tuesday.
Recalls in several European countries
There have already been recalls for certain products from different brands in Finland, the Netherlands and Denmark. For example, the Dutch Food and Consumer Product Safety Authority (NVWA) warned against certain chewing bones from the ‘Barkoo’ brand. Authorities announced at the end of the year that they were being sold in the country through Zooplus’ online stores. The chewing bones are suspected of causing serious neurological disorders in dogs and studies are underway.
Chewing bones from the brand “Barkoo” are also available in Austria in the online shop “Zooplus”. In Denmark, manufacturer Chrisco recently recalled certain dog chews sold in several markets across the country as a precaution. The background was reports of behavioral changes in dogs eating the products, the report said.
The term ‘werewolf syndrome’ for the abnormalities in dogs is used colloquially – because, according to their owners, the dogs often howl like a wolf – and is not a veterinary term.
