Coyote? The only coyote you might find in Switzerland would be in a zoo and even then I am not sure if we actually have a coyote in a zoo. I once saw this hound in town, standing on the steps to our cathedral. He has the looks of a coyote, perhaps not the yellow colouring of a coyote and I am sure it has a normal bark. There would be nothing howling about this dog, but it is the best I can do.
On a closer view it could be a coyote: at least its ears look big enough and it has that sly look in its eyes.
