Why Do Dogs Always Want to Eat Food?

Most dog lovers and dog owners will tell you that most pet dogs always seem to be hungry.

They get well fed, given some snacks and chews, and still beg when they see humans eating their food.

When they get fed, they wolf down their food as if it were their first meal in weeks!

Why is this? Why do dogs always want to eat more food? Why are they always hungry?

Let’s find out why and then look at what to do about it if this sounds like your dog.

Why Are Dogs Always Hungry and Want to Eat More Food?

The reason why many dogs always want to eat more food is due to their evolution.

Way back in time, their evolutionary ancestors would have always been trying to get enough food to stay alive.

So when they found food, they would gorge on it because they didn’t know when they would get their next meal.

How Evolution Affects Your Dog’s Appetite

Dogs have evolved from an ancient species of wolf called the Late Pleistocene wolf.

The species is now extinct but is very similar to wolves around today.

Your dog’s ancestors would have had to work very hard to survive.

They would have had to hunt for many hours, often falling and going hungry for days at a time.

So, when they managed to kill their prey or stumble across some fresh carrion, they would eat as much as possible.

They would do this to take as much advantage as possible of the meal because it might be a long time until their next, and they would need as much sustenance as possible to survive.

So it could be that your dog never seems to get full because the ancient wolf part of their brain still thinks they need to gorge on food in case their next meal is days or weeks away.

If you think about it, humans are the same to some extent. Many of us struggle not to overeat, especially high-calorie food such as sugar and fat.

This is because our ancestors never knew when their next meal would be, so they also would gorge themselves to store up calories for a later day.

If you are unsure how much food they need to eat, please consult your vet for advice.

What Can You Give Your Dog to Make Them Feel Full?

Avoid foods filled with air and water – Some cheap kibbles are filled with air and water.

It would be best to avoid these as your dog won’t find them satiating.

Give them high-fiber food – High-fiber food will keep your dog feeling fuller for longer.

Add vegetables to their meals – Vegetables are very low in calories but high in satiating fiber, so mix some with their regular food to help fill them up.
