Yer as fady said..they pick up on your body language, They know when your sad and when your happy, Its strange..people say dogs have a sixsence aswell. clever things
i Believe a dog knows some english to a extent, But only what they have been taught to understand tho, like when i say to my old staffy..omg look over thereeee She goes flying off across the room to look for something she don't even have a clue whats shes looking for lol, And she also knows f off and alot of other words aswell, My dogs know alot of words i say, When i tell them to move over, They move, When i tell em to get out the way when im hoovering, They go, they know alot of english Including the basic training words, Which also can be taught with signals aswell, Coz i have 2 deaf dogs and 1 can lip read beleive it or not.
So do dogs understand what we are saying? i think not..do they understand words signals and sentances what they have been taught? yep
