Top 10 Reasons Why Your Dog Won’t Eat and How to Help

As a dog owner, it’s concerning when your furry friend refuses to eat. Not only does it affect their health, but it can also be a sign of an underlying issue. In this article, we’ll cover the top 10 reasons why your dog won’t eat and how to help.

1. Illness or Pain

If your dog is refusing to eat, it could be a sign of an illness or pain. Dogs can’t communicate their discomfort like humans, so a lack of appetite may be their way of telling you that something is wrong. Some illnesses that may cause your dog to stop eating include:

  • Dental problems
  • Sore teeth
  • Gum disease
  • Gastrointestinal issues
  • Inflammation of the stomach or intestines
  • Pancreatitis
  • Kidney disease
  • Liver disease
  • Cancer

If you suspect that your dog may be ill or in pain, it’s important to take them to the vet for a check-up.

2. Change in Routine

Dogs thrive on routine, and any changes to their daily routine can cause stress and anxiety, which can lead to a loss of appetite. Some common changes that may affect your dog include:

  • Moving to a new home
  • A new family member (human or animal)
  • Change in work schedule

To help your dog adjust to the new routine, try to maintain consistency in their feeding schedule, exercise routine, and playtime.

3. Boredom with Food

Just like humans, dogs can get bored with their food. If your dog has been eating the same food for a long time, they may become disinterested. To make mealtime more exciting, try switching up their food, offering different flavors and textures.

4. Anxiety or Stress

Just like changes in routine, anxiety and stress can cause your dog to lose their appetite. Some common causes of anxiety in dogs include:

  • Loud noises (fireworks, thunderstorms)
  • Separation anxiety
  • Trauma (abuse, neglect)

To help your dog manage their anxiety, try providing a safe and quiet space for them to relax, using calming aids (such as pheromone diffusers), and spending more time with them.

5. Age

As dogs age, their metabolism slows down, and they may require fewer calories. Additionally, senior dogs may experience dental problems, making it difficult and painful to eat. If you have a senior dog, make sure to provide them with a low-calorie, easy-to-chew food.

6. Medication

Certain medications can cause nausea, leading to loss of appetite in dogs. If your dog has recently started on a new medication, speak with your vet about any potential side effects.

7. Unappetizing Food

Sometimes, the reason why your dog won’t eat is simply that they don’t like the food. If you’ve recently changed their diet, they may not enjoy the new flavor or texture. To encourage them to eat, try mixing in some wet food or a small amount of something flavorful (such as chicken broth).

8. Food Allergies

If your dog is allergic to certain ingredients in their food, they may experience gastrointestinal discomfort or nausea. If you suspect that your dog has a food allergy, speak with your vet about a hypoallergenic diet.

9. Dental Problems

Dental problems, such as sore teeth or gum disease, can make it painful for your dog to eat. If you suspect that your dog has dental issues, take them to the vet for an exam.

10. Feeding Schedule

If you’re free-feeding your dog, meaning that you leave food out all day, they may not be interested in eating when it’s time for their regular meal. Try feeding them at scheduled times each day, removing any uneaten food after a certain amount of time.

In conclusion, there are many reasons why your dog may refuse to eat. By identifying the cause, you can help your furry friend get back on track to a healthy, happy appetite. Remember, if you’re ever concerned about your dog’s eating habits, it’s always best to speak with your vet.


Q: My dog has stopped eating suddenly, what could be the reason?
A: Sudden loss of appetite in dogs can be caused by various factors such as illness, stress, change in environment, or even dental problems. It is important to monitor your dog’s behavior and consult a veterinarian if the loss of appetite persists for more than 24 hours.

Q: Can I offer my dog human food if they are not eating their regular food?
A: It is not recommended to feed your dog human food as a substitute for their regular diet. This can lead to an unbalanced diet and cause health problems in the long run. However, you can try offering your dog a different type of dog food or adding broth or shredded chicken to their regular food to entice them to eat.

Q: My senior dog is not eating as much as they used to, is this normal?
A: As dogs age, their metabolism slows down and they may not need as much food as they used to. However, sudden or significant changes in appetite in senior dogs can be a sign of an underlying health issue. It is important to consult with a veterinarian to rule out any potential health problems and adjust their diet accordingly.
