Over the past few days, officials say, a mystery disease has killed a number of dogs in Norway. The Norwegian Food Safety Authority reported that up to 40 dogs were sick with vomiting and diarrhea, and several died later. The first cases were in the capital Oslo, and in at least 13 other towns have since been reported.
The Veterinary Institute said it was unclear whether the cause was two suspected types of bacteria found in autopsies. National Norwegian broadcaster NRK reports that the condition has killed a total of 25 dogs. However, the Norwegian Food Safety Authority has not confirmed this.
According to Swedish newspaper GT, a dog in neighboring Sweden was also admitted to the veterinary hospital after appearing at a show in Trondheim’s Norwegian city. The Norwegian Veterinary Institute said its pathologists found that three dogs had signs of a bloody intestine and that common causes such as salmonella and rat poison had been ruled out.
Speaker of the Food Safety Authority Ole-Herman Tronerud told NRK that the disease seemed “very serious for a dog, but we still don’t know if it’s contagious or just a series of individual cases.”
To prevent contact with other canines, the agency has recommended dog owners to maintain pets on a lead.
