Both my dogs love peanut butter. I think it's built into a dog's genetic code.

Cici is like her mama (me) and likes super chunk Skippy, whereas Charlie is more of a creamy peanut-butter lover, like his mama (my sister). I haven't given it to them in a long time, though. I really prefer to give them organic or freshly made, so I know exactly what goes in it, but I've yet to find a brand of organic super-chunky peanut-butter.
Ah, the trials of life.
Now, you've done it! Made me hungry! (Runs off to find super chunk!!!!

)
EDIT: I have the super-chunk now. Mmmmmm, yummy to my tummy. Oh, and Lola's super-cute. I was so distracted by the prospect of some super-chunk that I forgot my manners
