I love these stories
. My basset, Nell, is the most quirky dog I've ever had. She likes her manky old chewy bone in the hearth, not tidied away, so puts it back and gives me a withering look. She wanders off to bed at 11 o'clock, so if I haven't ensured she's been in the garden for a wee just before that, she'll watch me get ready for bed, get in, and then tap me to say she wants to go in the garden! When I get up in the morning, she only comes downstairs when she hears her food bowl being filled. She plays cricket with her rubber chicken and a ball, which she pushes round the room - don't know where she learned that! She sits watching the front door if I hoover the carpet - must be having visitors! 
I guess I have reinforced behaviour by laughing or praising her, giving her more attention when she does these things. I sometimes catch her weighing me up. It's fascinating how dogs so quickly develop habits from humans' lack of understanding about how they interact with us.
