EU Concerns:

The chews are potentially linked to a condition dubbed “werewolf syndrome,” characterised by symptoms such as panic attacks, aggression, spasms, seizures, and in rare cases, death.

After doing a quick internet search today, these products are still available from many online retailers, raising concerns about their potential accessibility despite the warning.

While there is no confirmed distribution in the UK and no cases have been reported, some of these products may have been purchased online from international sellers.

Tina Potter, Head of Incidents at the FSA, stated:

“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.”

Advice for Dog Owners:

• Stop using affected chews immediately if they are in your possession.
• Seek veterinary advice if your dog shows symptoms such as sudden behavioural changes, seizures, or other signs of distress, and inform your vet about the food and treats your dog has consumed.

Advice for Vets:

• Be vigilant for symptoms, including aggression, howling, crying, and seizure-like behaviour.
• Suspected cases can be reported to the Animal and Plant Health Agency’s (APHA) Small Animal Surveillance.

The FSA continues to work with EU authorities to monitor the situation and provide updates as new information emerges.
