Mystery sickness strikes dozens of dogs in Norway, killing at least 25

A mystery sickness struck dozens of dogs in Norway, killing at least 25 and prompting authorities to warn owners to keep their pets on a lead and away from other canines until the cause is established.

Ten dogs fell ill on Saturday 7th and Sunday 8th September, 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 over the weekend.
