Just to clarify: he wasn’t completely wild. He was well-socialized and he wasn’t aggressive about food - you could safely stick your hand in his mouth and pull food out. Beyond that, I didn’t bring him to places where he could get in trouble that way.
I get that “badly trained” can mean various things including simply neglecting a dog, but in the context of this meme I just meant that my dog wanted to eat whatever people were eating (in moderation) and he whined a lot if someone refused to play with him.
