Idk why I'm doing this...
If a dog is looking away and only looks back at you when you pet them, they're eventually gonna bite you.
If the dogs tail is curved inwards, it is scared, avoid contact if growling.
If one ear is straight and the other is down, they're actually asking you if you're declaring a fight or not. Running away is like starting one.
Staring at a dog is like telling them "COME AT ME BRO. FIGHT ME."
