Press release

The past week, more than 20 dogs in Norway have died or became seriously ill in yet unknown diseases. There are no confirmed cases of the illness outside Norway.

The affected dogs experienced symptoms of vomiting and diarrhea and turned severely ill or died within a short period of time. Several dogs are currently being treated at animal hospitals and clinics in the country. The Norwegian Veterinary Institute has performed autopsies of the first seven dogs but have not yet concluded the cause of deaths. Viral, bacterial, fungal and parasitic causes are being evaluated. According to the Norwegian Food Authorities, there are currently no indication that food, rat poison, salmonella or campylobacter are causing these illnesses.

Sasja Rygg is veterinarian at in AniCura Norway. She was first to inform the general public and authorities about the disease.

-     We noticed similar symptoms on an unusually large number of patients in the Oslo region and have thereafter experienced cases in other parts of the country as well. These dogs get severely ill very rapidly and we recommend pet owners in Norway who experience these symptoms to get in touch with their veterinarian, says Rygg.

Precautions in Norway

The Norwegian Food Safety Authority encourages all pet owners in Norway to limit close contact between dogs and to keep dogs on leash.

-     There are still no confirmed cases of the same illness among dogs in our neighboring countries and we take a clear stand against speculations on this matter. However, we do recommend pet owners in Norway to take precautions and follow advice from the Norwegian Food Safety Authorities, says Rygg.

Advice to pet owners in Norway:
