I have kept a dog for two years. Last time I walked my dog with my friend, he joked that he wanted to eat. What does that mean? Can you make such friends?

Hehe ... from your description, I personally think it's better for such friends to keep their distance. First of all, he should know that you have kept this dog for two years, which is actually a family significance and your favorite. As a friend, since I chose to walk my dog with you, I should have some love and shouldn't make such jokes. However, it may be just a joke. If you really want to be friends with him, you should keep your distance. At least this person is a little heartless or cruel, and your own dog can be killed and eaten.
