In answers to emailed questions posted on his web site, Mr Putin said: “Sometimes, Koni leaves a room full of journalists with a very pleased expression on her face and biscuit crumbs around her mouth."
"Therefore, I appeal once again, this time via the internet, to all my visitors. Please. Don't feed my dog."
Koni is a curvaceous black labrador who made headlines by giving birth to eight puppies on the eve of 2003 parliamentary elections.
She frequently sits in on Mr Putin's meetings with foreign heads of
state.
