QuestionIs it ok to give a Golden Retriever popcorn?
AnswerA little popcorn shouldn't hurt. Watch the salt. After all, corn is a popular ingredient in dog chows. Of course, the food kooks are highly negative about it, but I suspect many of them are selling more expensive chows.
Big thing is to not over do it. Even if corn goes into many dog chows, so do a of of other things. Corn alone is nowhere the complete and balanced diet dogs need. So yes, if you fix yourself a bowl of popcorn, give it a few kernels.
Keep an eye on its waist. See http://www.puppychow.com/products/popup_body_condition.aspx Adjust its food and exercise to reach its ideal body condition, and it will have a longer, active life.
