There is nothing scarier for a pet parent than putting down a bowl of fresh food and watching your dog walk away. You love your dog. They are your best friend. Usually, they run to the kitchen as soon as they hear the food bag open. But today, they just look at it and walk away.
You are likely concerned and asking yourself, ‘Why is my dog not eating?
Do not panic. This is a very common problem. Sometimes, the reason is simple, like they are just bored with their food. Other times, it might be a tummy ache. In this guide, we will look at every reason why dogs stop eating. We will use the latest advice from vets and dog experts to help you figure out what to do.
Introduction: Understanding Your Dogās Appetite
Dogs are usually very good eaters. Some dogs act like they have never seen food before! So, when that appetite goes away, it is a red flag.
When a dog stops eating, doctors call it “Anorexia.” This doesn’t mean the dog wants to be skinny. It just means they have lost their desire to eat.
There are two types of this problem:
- Partial Anorexia: This happens when your dog rejects their regular food but is still willing to eat snacks or nibble a little.
- Complete Anorexia: Your dog refuses to eat any food whatsoever.. Not even a piece of chicken or a tasty treat.
Before we try to fix the problem, we have to find the cause. Is it their body? Is it their mood? Or is it simply the weather?
Letās find out.
The Emergency Check (Read This First)
Before we talk about picky eaters, we need to make sure your dog is safe. Sometimes, why is my dog not eating is a question that needs a vet (animal doctor) right away.
Use this simple ‘Traffic Light’ guide to determine what action to take:
Go to the Vet Immediately
If your dog refuses food and shows any of these symptoms, act immediately.Go to the vet now.
- Vomiting or Diarrhea: If they are throwing up or have loose poop, they are losing water fast.
- Lethargy: This means they are very tired, won’t play, or won’t get up.
- Hard Tummy: If their belly feels hard like a drum and they cry when you touch it.
- Not Drinking Water: A dog can go a few days without food, but they cannot survive long without water.
Watch Them Closely
If your dog seems okay but just skipped one meal:
- They are still drinking water.
- They are playing and acting normal.
- Their gums are pink (not white or pale).
- Action: You can wait 12 to 24 hours to see if they get hungry again.
Probably Behavioral
- The dog won’t eat dinner but begs for your pizza.
- They seem happy and energetic.
- Action: This is likely a “picky eater” problem. We can fix this at home!
Medical Causes (When the Body Hurts)
If your dog is not feeling well, the first thing to go is their appetite. Think about when you have the flu. Do you want to eat a burger? Probably not. You just want to sleep. Dogs are the same.
Here are the most common medical reasons why is my dog not eating.
1. Dental Disease (Tooth Pain)
This is very common but owners often miss it. If your dog has a broken tooth, a loose tooth, or swollen gums, eating hurts. Crunching on hard dry food (kibble) causes sharp pain.
- Signs: Bad breath, drooling, or chewing on only one side of the mouth.
- What to do: Open their mouth gently and look. If the gums are very red or you see brown stuff on the teeth, they need a doggy dentist.
2. Upset Stomach (Indigestion)
Dogs are curious. They eat things they shouldn’t. Maybe they ate a bug, some grass, or a piece of trash. This can give them a stomach ache or nausea (feeling like they want to throw up).
- The “Eating Grass” Clue: Often, dogs eat grass to make themselves throw up when their tummy hurts. If they do this, let them rest their stomach for 12 hours.
3. Infections and Viruses
Just like kids catch colds at school, dogs catch bugs at the park.
- Parvovirus: A very dangerous virus for puppies.
- Kennel Cough: A bad cold for dogs.
- If your dog has a fever, they will not want to eat.
4. Joint Pain (Arthritis)
This sounds strange, right? Why would a sore leg make a dog stop eating?
Well, if your dog is old and their food bowl is on the floor, bending down to eat might hurt their neck or shoulders. Because it hurts to bend down, they choose not to eat.
Behavioral Causes (Itās All in the Mind)
Sometimes, the dog is physically healthy. Their body is fine, but their mind is worried. According to new surveys in 2024 and 2025, mental health in pets is becoming a big topic.
1. Stress and Anxiety
Dogs love routine.They thrive on a consistent daily routine.. If you change that routine, they get stressed. When dogs are stressed, they lose their appetite.
Things that cause stress:
- Moving House: A new home smells different and feels scary.
- New Family Members: Did you bring home a new baby or a new pet? Your dog might feel jealous or crowded.
- Loud Noises: Thunderstorms or fireworks can scare a dog so much they won’t eat for hours.
2. Separation Anxiety (The “Back to Work” Problem)
During the pandemic, many people stayed home. Now, people are going back to offices.
If your dog is used to you being home all day, and suddenly you leave for 8 hours, they get sad. A sad dog often waits by the door and refuses to eat until you come back.
3. The “Picky Eater” (Stubbornness)
Some dogs are smart. They know that if they refuse their dry food, you might get worried and give them cheese or chicken.
If you have a habit of feeding your dog table scraps, you have taught them a lesson: “Wait long enough, and the good food will come.” This is not an illness; this is a battle of wills!
Environmental Causes (Check Your Surroundings)
Sometimes the answer to “Why is my dog not eating” is right in the room with them.
1. The Weather (Heat)
In the summer, when it is very hot, dogs move less. Because they are running less, they burn fewer calories. This means they are not as hungry. This is normal. As long as they are drinking water, eating a little less in summer is okay.
2. “Whisker Fatigue” (The Bowl Problem)
This is a new discovery for many pet owners.
Dogs have whiskers on their snouts. These whiskers are very sensitive, like your fingertips. If you give your dog food in a deep, narrow bowl, their whiskers touch the sides every time they take a bite.
This can feel annoying or even painful after a while.
- The Fix: Try putting their food on a flat plate. If they eat it immediately, the problem was the bowl!
3. Old or Stale Food
Smell your dogās food. Does it smell like dust or old oil?
Dry dog food has an expiry date. Once you open the bag, the fats in the food can go bad after a month. Dogs have a super-powered nose. If the food smells slightly “off” or stale, they won’t touch it.
Is Your Dog Drinking But Not Eating?
This is a very specific situation. If your dog is drinking water normally but refuses food, it tells us a few things:
- They are not dehydrated: This is good news.
- It might be a tummy ache: Often, when a dog feels nauseous, they know food will make them vomit, but water feels soothing.
- It might be dental pain: Chewing is hard, but lapping up water is easy.
If this lasts for more than 24 hours, see a vet.
How to Get Your Dog to Eat (Solutions)
Okay, we have looked at the causes. Now, letās look at the solutions. If your dog is healthy (no vomiting/diarrhea) but just won’t eat, try these tricks. These are updated tips based on what works for pet owners today.
The Microwave Hack
Dogs decide what to eat based on smell, not taste. Dry food doesn’t smell very strong.
- What to do: Put their food in a microwave-safe bowl. Add a tiny splash of water. Heat it for only 10 to 15 seconds.
- Why it works: Heat unlocks the smell of the food. It makes the food smell “meaty” and fresh.
Tasty Toppers
You can add healthy “human foods” to their bowl to make it exciting. Be careful to only use safe foods.
Safe Toppers (Good):
- Bone Broth: Make sure it has NO onions and NO garlic.
- Plain Yogurt: Just a spoonful. Good for their tummy.
- Pumpkin: Plain canned pumpkin (not pie filling) helps digestion.
- Warm Water: Makes a gravy with the dry food.
Unsafe Toppers (Bad):
- Onions or Garlic (Poisonous to dogs).
- Chocolate.
- Grapes or Raisins (Very dangerous for kidneys).
- Spicy food.
Strategy 3: Cut Out the Treats
If you want to know if your dog is truly not hungry or just picky, stop all treats for 24 hours. No biscuits, no cheese, no table scraps.
Put their food down for 20 minutes. If they don’t eat, pick it up. Offer it again at the next mealtime. A healthy dog will not starve themselves. Once they are truly hungry, they will eat their meal
Strategy 4: Exercise
Sometimes, a dog isn’t hungry because they haven’t burned any energy.
Take your dog for a long walk or play fetch for 20 minutes before dinner. Exercise “jumpstarts” the metabolism and makes them hungry naturally.

Frequently Asked Questions (FAQs)
Q: Can a dog starve themselves if they don’t like the food?
A: A healthy dog will rarely starve themselves. They might go on a “hunger strike” for a day or two to test you, but their survival instinct will kick in and they will eat.
Q: Why is my old dog not eating?
A: Senior dogs (older than 7-10 years) often lose their sense of smell. IIf the food has no scent, they will not touch it.. Warming the food helps a lot for older dogs. They might also have tooth pain.
Q: Should I change their food brand?
A: If you change food suddenly, it can cause diarrhea. If you want to switch, mix the new food with the old food slowly over 7 days.
Q: How long can a dog go without eating?
A: A healthy dog can survive 3 to 5 days without food (as long as they drink water). However, you should not wait that long. Call a vet after 48 hours.
