Or it leaves us with “the dog was unstable”.
What can you say to a dog to offend him to the point of violence?
How terrible! You can get a ‘crazy’ dog. My aunt had a beautiful cocker spaniel who was babied but, sometimes, would get this crazy look in his eyes and turn on you. Petting him one minute, he snapped at you the next. Never seriously bit anyone but something was unstable there. He never did it to her, and she had cockers before and after who were nothing like that. Guess dogs can produce a wacky one at times, just like humans.
