Food Standards Agency warns UK pet owners may have bought ‘unsafe’ bone chews online. An urgent warning has been issued for pet owners over a dog treat that has been linked to the potentially fatal “werewolf syndrome”. The Food Standards Agency (FSA) says a certain brand of bone chews have led to severe symptoms reported in the EU. A health authority in the Netherlands has cautioned owners over feeding their pets chew bones from the company Barkoo after a dog reportedly died, but there has been no confirmed distribution of the products to the UK.

In the UK, the FSA warned the China-made chews have been linked to dogs experiencing “werewolf syndrome”, which can cause sudden behaviour changes among dogs, with symptoms including panic attacks, aggression, spasms, epileptic fits and in some cases death. Tina Potter, head of incidents at the FSA said: “While there is no confirmed distribution of affected products to the UK, there is the possibility that some consumers may have purchased these online from international sellers.
“No unsafe dog chews have been identified but, based on international investigations so far, we are advising dog owners to avoid feeding the affected chews to dogs as a precaution. “There is no evidence to suggest these products present any risk to human health.”. Dog owners have been advised to stop feeding their dogs the products if they recognise them, and to seek veterinary advice if their pet becomes unwell.
