I don’t trust anyone who doesn’t like dogs, and I don’t trust anyone who provokes anxiety and hostility in dogs.
Some dogs are really good at ferreting out losers, even when the loser is trying to con the dog.
Cats are too for that matter, but it is much less demonstrative.
Heard at a dog show: (A)”My dog doesn’t like my BF.”
(B) “Get rid of him.” (A) The dog? (B) “No. The BF.”
