Can my dog have corn & pop corn?

Avoid

Containing several vitamins and minerals, corn is a popular cereal. Due to its low price, corn is often found in many commercially available dog foods. However, corn is not more than cheap filler – it is also a good source of proteins, carbohydrate, linoleic acid, dietary fibers and antioxidants.
The corn used in these foods is processed and pulverized. However, giving cooked and canned corn to dogs is not a good idea simply because they will not be able to properly process it. In addition, the cob poses a chocking hazard and an intestinal obstruction hazards.

Popcorn poses a choking hazard for dogs. In addition, the kernels can easily get stuck between the dog’s teeth, causing pain and discomfort. However, and occasional treat of plain and fully air-popped popcorn is not forbidden. Flavored popcorn, heavily salted popcorn and popcorn covered with toppings should be avoided.

All in all, although not toxic, corn and popcorn are not recommended for dogs.
