He looks so afraid. Probably got shocked from his collar..
I know when a dog looks like this it's because of fear.. and her face, the way she looks at him gives me chills!
And why did she cut the video the second you would see his whole body? And then her face right after, that is not a person that loves her dog or the dog loving his owner.
( sorry my english, im from sweden but I hope you're understanding what I'm trying to say 🥺) this makes me so sad, my heart breaks for this puppy.
