I have just spent 4 whole minutes telling my dog why she isn't allowed to jump around or climb stairs, and why it's short lead walks for a few days until her hip feels better. I'm sure she listened and understood ever word! I also spent another good few moments explaining what the loud bang was next door that made her bark!
My daughter thinks I'm bonkers but I literally chat to my dog alllll the time - I love to think that they understand ever word and their brains are saying "ah OK mum - I understand now"!!!!!!
Mind you, she doesn't seem to understand "SSTTTTOOOPPPP" when she sees a squirrel........
