My dog eat a oat and honey bar, last night, she is just laying around today, and her belly look somewhat swollen, is she OK?

Oats and honey are perfectly fine for dogs. Unless of course she has some sort of allergy. A bloated stomach usually indicates something else. When is the last time she was to the vet for a once over? Up to date wit worm meds?

Could she possibly gotten into anything else or eaten the wrapper?
