Dogs in Norway dying of unknown illness

There is a bit of an update. They have ruled out a number of causes. People are being warned to be careful with their dogs.
One possibility could be mushrooms which can be quite toxic and are growing in greater numbers this year. This idea is being investigated.

Knowing how dogs will eat anything, mushrooms could be a possibility. It would be less scary than an infection spreading from dog to dog. Some of the dogs who have been quite ill have not had contact with other dogs. It makes an infection less likely. 
If it is the mushrooms dog owners will have to be very careful when their dogs are outside.
I hope they find out something before more dogs become ill and even die.
