Can dogs eat edamame

No, edamame causes dogs to be bloated and gassy.

The soy beans can cause your dog to be gassy (though not all dogs have this problem). However the husks of the edamame, which you likely discard, are fine.

Our Cane Corso -loves- the husks. We don't give her all of them, fear of toooooo much fiber, but she's happy to get 4-5 tossed to her while we are munching.
