Why Are Dogs So Greedy? [Behavior Explained]

Dogs are known to be greedy from time to time, whether they are begging for food, stealing food or even just gobbling all their food in 2 seconds flat. It’s certainly not a secret that dogs love food, and will do just about anything to get as much as possible. But why do dogs come across in this greedy way? Well, there are actually many reasons why dogs display behavior that is interpreted as greedy. The main ones are instinct and evolution, boredom, overfeeding, incorrect training and reinforcement, health issues, anxiety and stress, and even specific breed characteristics.

So as you can see the answer isn’t very clear, and a little further understanding might be required to really understand why your dog specifically seems to be greedy.

Top Reasons Why Dogs Are Greedy

Instincts and Evolution

Most people would argue this reason is the main reason why dogs are seen by many people to be greedy animals. The ways dogs think and behave are largely influenced by their ancestral history dating back to wolves. Before dogs were domesticated animals they had to survive in the wild where they had to compete viciously against other animals and even their own pack for food. This created the instinct to eat as quickly as possible to prevent others from stealing their food. It’s a survival instinct that seems to have stayed with most breeds of dogs.

Dogs fear losing their food because its seen as a resource essential to survival even if they already have an established routine, their survival instincts have been hardwired into their brain for hundreds of years.

A lot of dogs will also eat as much as possible, more than often anything you put in front of a dog will get eaten and it’s rare they will get full. I’ve even heard of dogs that will eat to the point where they make themselves physically sick because they don’t know when to stop. This behavior stems from their natural instincts to survive too, in the wild, regular meals are scared and not guaranteed so the opportunity to fill up on food is something that must be taken advantage of.

Lack of Mental Stimulation

It’s not uncommon for some dogs to get bored from time to time. If they aren’t getting enough exercise and mental stimulation, they’ll start looking for ways to keep themselves entertained. And let’s face it, what’s more, exciting to a dog than some delicious food?

Food is often used to train and reward dogs for good behavior. But sometimes, if food is their main source of stimulation, dogs can become fixated on finding more and more treats. This can cause them to lose interest in other activities like walking or hunting and instead focus on seeking out snacks and meals. When dogs are rewarded with treats, their brains release dopamine, which can create an addiction-like response in their brains. If this becomes their only form of stimulation, it can lead to obsessive behaviors related to food or treats, and even lead to aggressive behaviors like guarding their food or stealing food from others.

All of these behaviors combined can lead to a new issue: overfeeding. 

Overfeeding Your Dog 

Overfeeding a dog regularly is likely to manifest into a big issue. When a dog is given more food than they need, they become used to it. Not only do they become used to it but some dogs may develop a sense of entitlement. It’s like having a spoilt kid in a way, if you give them everything they expect everything too. Now, this slowly becomes a problem because overfeeding and spoiling your dog with excess food leads to behavioral problems and health issues.

In terms of behavior, your dog is like to become possessive, steal food, and more often than not beg for food. Additionally in terms of health, overfeeding your dog will lead to your dog becoming overweight or even obese. Overweight or obese dogs are likely to develop health-related issues because of their size.

Incorrect Training, Treatment by the Owners

The way we train dogs has a huge impact on their behavior. It’s unfortunate but the truth is a lot of dog owners simply don’t understand how to train their dogs. Most commonly we see dogs begging for food, which is annoying of course and we frown upon it, but sometimes there’s the odd occasion where maybe you’ll break and give them something.

Once this behavior has been rewarded even once, a dog has learned that in the future, if it begs there’s a chance that it can be rewarded with food. Dogs are intelligent animals and they understand that if they are persistent then it pays off.

You have to think of it in the sense that, if you give a dog some food, then you are rewarding them for whatever they are displaying at that current moment. This will then motivate them to replicate that behavior in the future because they understand it gets them food. 

This is obviously used in a positive way too, like training dogs to sit, stay, etc. So rewarding dogs shouldn’t be a negative thing. Just make sure you only reward your dog when they are displaying positive behaviors and not negative ones.

Health Issues

When dogs experience health issues, it can impact their metabolism, appetite, and digestive system. These problems can cause dogs to develop an increased drive to eat, as well as negative behaviors related to food.

One common health issue that can lead to these behaviors is hypothyroidism. This condition occurs when a dog’s thyroid gland is underactive, which can cause weight gain, lethargy, and an increase in appetite. Dogs with hypothyroidism may also engage in hoarding behaviors, as they try to ensure they have access to enough food.

Another health issue that can contribute to greedy behaviors in dogs is diabetes. Dogs with diabetes are unable to use nutrients like glucose efficiently, which can leave them feeling hungry more often. This can lead to a heightened drive to eat and a preoccupation with food.

Anxiety and Stress

Dogs are like humans in that they look for things that bring them joy and comfort. And what brings a dog more happiness than food? But just like some people, dogs may overeat when they’re stressed or anxious. The only difference is that dogs can show this behavior through begging, food guarding, or even aggression.

It’s important to notice these tendencies in your dog and address them in a healthy way. This can mean seeking help from a professional, teaching your dog new ways to cope with stress, or creating a safer and more secure environment for them. By taking steps to manage your dog’s eating habits, you can help them live a happy and healthy life.

Breed Characteristics

Just like people, different dog breeds have different personalities and characteristics. Some breeds, like Basset Hounds and Beagles, have been bred for their strong sense of smell and food-seeking tendencies. So if you have a dog with these traits, it may be more likely to display greedy behaviors around food.

But it’s not just about the breed. A dog’s personality and training can also affect its relationship with food. Knowing your dog’s breed and personality can help you understand their food-seeking behaviors, and take steps to manage them. This could mean providing appropriate training or taking measures to keep food out of reach.

As a dog owner, it’s important to be aware of your dog’s tendencies and take steps to ensure their health and well-being. By understanding your dog’s breed-specific characteristics and individual personality, you can create a plan to manage their food-related behaviors and keep them healthy and happy.


Dogs can be greedy for various reasons such as their evolutionary history, lack of exercise, overfeeding, training, health issues, and breed characteristics. It’s important for dog owners to recognize these factors and take steps to manage their dog’s diet and behavior. By providing the right training, reinforcement, and veterinary care, dogs can develop healthy habits that will benefit them throughout their lives.
