The dog I had growing up, a miniature poodle looooves pacifiers!
Dugan's about 13 now, and still likes to play with them. And he looks so cute with a paci in his mouth.
When he was little, he chewed through them quickly- but they were a great little toy.
I haven't tried them with Dobby yet (we just got him last week!)- since I don't have any babies around to nab a binky from

.
That's just my experience, hope it helps.
