Of course I asked. I mean, look at that sign!
There I was picking up Houdini Iko after she tortured every person at the dog groomer her bath today, and this sign taunted me from the counter.
Me: Laura, I’m asking about your bag of 20 duck feet. Are they real?
Laura: Yes they are.
Me: Ok, that is more than I needed to know about them.
Then I spent the rest of the day picturing Iko with 20 duck feet in her mouth at one time because she jams as many items in there as she possibly can. Someone please tell me why giving your dog duck feet (20 or any number for that matter) is desirable.
And what do they do with the rest of the duck?
UPDATE: alas, Mashable has an answer to all those footless ducks
i could cry but i don't have time 
I’m pretty sure I’m eating the rest of the duck.
It’s fatty so I like to poke the skin a bit, slow roast it and put an orange glaze on top… you can cheat with salt and orange marmalade.
But are you eating 10 ducks?
Never heard of this. So they are like doggie chew toys?
