This is Russia. The dog is a miniature pinscher. He is carrying what must be his cat companion across his neck and shoulders! I don’t know for the life of me why he’s doing it other than to take him home. That is the way it looks in the video. I’ve got a feeling that this happens all the time because the dog clearly seems to enjoy doing it and has a method which the cat has found acceptable. You can see that the cat is perfectly happy to be carried like this so I’m gonna say that this is a routine between the two. I have never seen anything like it before between a cat and a dog. Cats and dogs together never cease to surprise me but it does not surprise me to see a cat and a dog being best mates.
I hope that the video plays all right. On occasions it has stopped for me.
