The video does not explain how he injured his front paws so badly that they had to be amputated or that is the way it looks. The video doesn’t explain any of this except at the end we see that this incredibly sweet dog has no front paws. It looks as though it may be frostbite. I have seen this in cats before. However, more importantly, the overwhelming impression that you get from the video is that this dog has the most beautiful character. He or she (I don’t know the sex) is incredibly calm, compliant and friendly. He’ll be a great companion.
When these two guys trek six hours to a mountaintop village to rescue the dog he pretty well immediately lies down on one of the guy’s laps to say in very loud terms but completely silently that he needs a human companion to rescue him, to look after him, to love him for the rest of his life. We don’t know whether he achieved his goal but once they got down a restaurant owner said that he would foster the dog having seen the video on Facebook. It ends there and I wish it hadn’t.
