shes in love with toes

..when me / a family member walks into the room, she kind of lays down, puts her ears back, and licks our toes to death..
i dont want her to do this! id hate it if she did it when she got older and it became an annoyance.
ive tried bitter apple spray, and it works, but only is your toes are really wet with it, when its dry it doesnt faze her..
ive tried saying no and sitting her at the other side of the room..
any help would be greatly appreciated..
Thanks
