Atypical behaviour observed
The wolf in question was a male animal, most likely born the previous year. Based on the observed symptoms, it had to be assumed that it was suffering from distemper or another disorder of the central nervous system. The animal was active during daylight hours, which is atypical for a wolf. It was apathetic, showed no wariness whatsoever, and did not respond to calls. The young wolf moved continuously in circles, and its gait revealed an injury to its right hind leg. Furthermore, the animal had a swollen face and its eyes were frequently closed, indicating a high sensitivity to light — a further symptom of illness.
This was not a new sight for the wildlife rangers, as in the preceding half-year alone, within the Herrschaft-Seewis supervision district, they had been forced to shoot around 20 animals suffering from distemper — in addition to foxes and badgers, this had also included a raccoon.
Encephalitis confirmed, distemper ruled out
The animal was immediately taken to the Centre for Fish and Wildlife Medicine (FIWI) at the University of Bern. Examination of the deceased animal found no evidence of the distemper virus. Rabies was also ruled out on the basis of negative test results. However, the animal had a clearly identifiable case of encephalitis. The laboratory findings are consistent with the clinical symptoms observed in the field.
A heartworm infestation (Dirofilaria) was also detected. This is the first time such a finding has been confirmed in a wolf in Switzerland. The examined animal also showed a high parasite burden in the intestines and lungs.
This case demonstrates how important it is to report animals with abnormal behavior to the wildlife authority without delay. The ongoing genetic analysis may shed light on whether the young wolf originates from the Calanda or the Morobbia pack. More on wildlife.

The position of IG Wild beim Wild: IG Wild beim Wild rejects recreational hunting. Our model is the canton of Geneva, which has managed without recreational hunting since 1974: without hunting seasons, without hunting dogs, without driven hunts, without high seats, without the animal cruelty and crime that go hand in hand with hunting season elsewhere. What has worked there for over fifty years disproves every position paper by JagdSchweiz. An association that bases its policy on claims it refutes in its own documents is not a professional organisation, but a factory for misinformation.
