If your canine companion is acting a little friendlier than usual this morning, they may have heard about Krispy Kreme's promotion celebrating National Dog Day today.

The doughnut shop known for its hot, fresh glazed doughnuts is offering "doggie doughnuts" at some locations Friday, while supplies last. Check out Krispy Kreme's website for a list of participating stores.

Krispy Kreme's doggie donughnuts are made with ingredients that are safe for our four-legged friends. The baked goodies cannot replace a full meal, so they're intended as a snack for sweet tooths on this special holiday. Here's what you need to know.

What ingredients are in the doggie doughnuts?

The doughnuts are made with ingredients safe for canines, and include whole wheat flour, peanut butter, sugar, vegetable fat and carob instead of chocolate.

Are they OK for older dogs and puppies?

Krispy Kreme said on its website the treats were specifically designed for dogs of all sizes and ages "by professional pet treat artisans."

"Older dogs with fragile teeth may find the treat difficult to chew, however, they will get softer the longer they chew or suck on them and are safe for your pet to consume."

Puppies may also find difficulty with the hard, baked treat, but can suck and chew on it to soften it.

How long do they last and should they be refrigerated?

Assuming your pet doesn't go through everything you purchased within minutes, the treats do not require refrigeration and will last for 12 months, according to Krispy Kreme.

What if a person eats a doggie doughnut?

The dog treats are not designed for humans, but they are made with human-grade ingredients. Still, doggie donuts could pose a choking hazard for small children. For any concerns, contact your health professional.
