If you own a Cockapoo, you will know why K is for Kiss !
I guess other dogs like to give kisses, but it seems to be something hard wired into a cockapoo.
Jessie has mastered the art of getting a kiss, despite being told repeatedly. we "Don't do lips"
Her technique is to sit on you, then when she has you pinned, she goes for it.
This is usually how she wakes us up in the morning too...
