My dog loves coffee too! I found out the hard way that even a tiny bit or coffee is bad for a chiweenie though. Now she gets milk, a tiny bit of sugar, and just enough decaf to give it a coffee taste. She drinks her coffee beside me every weekend.
My dog knows our routine when we are leaving and runs to her "bye bye spot". She will give a kiss to the person to leave but always does this to the person. I guess she hopes they wont leave without a kiss. I'M DYING! I CAN'T lol So sweet.
