Norwegian authorities haven’t been able to detect the cause behind an unexplained disease that is estimated to have killed dozens of dogs in the country in recent days, officials said.The Norwegian Food Safety Authority said that it had been informed of another six cases of dogs falling ill, with two them already dead, all with the same symptoms of vomiting and bloody diarrhea.Ten dogs fell ill on Saturday and Sunday, the national food safety authority said, four of which have since died. While most cases have been in the capital, Oslo, the illness has been reported in 14 of the country’s 18 counties, including the far north.
According to the Swedish newspaper GT, a dog in neighbouring Sweden was also being treated in a veterinary hospital after appearing at a show in the Norwegian city of Trondheim last week. All dog shows in Norway were cancelled this weekend.
The Norwegian Kennel Club said owners were so concerned about the spread of the illness over the weekend that its website crashed under the weight of demands for information. There are an estimated 500,000-600,000 dogs in Norway.In neighboring Sweden, the National Veterinary Institute said it had been swamped with questions from dog owners concerned over the spread of the disease across the border.
