All living things need food to survive. If it weren’t for it, everybody would get sick and eventually die. Your pet has always been like this; it requires a well-balanced and adequate diet to stay healthy and strong. But what happens if the dog refuses to eat its dog food.

It may be because of a medical or behavioral issue. In any case, dog owners who discover their pet hasn’t eaten today’s meal would be concerned, particularly if they have a healthy eater on their paws.

First and foremost, don’t be too upset!

Dogs can go for extended periods without feeding. In the meantime, you’ll need to do more research on why they aren’t eating and what would you do to assist them in regaining their appetite?

What Is The Maximum Amount Of Time A Dog Can Go Without Eating?

Most dogs can go three or five days without eating, and some can also go seven days or more. However, if your dog hasn’t eaten in more than two days, you can see a veterinarian.

Anorexia refers to a puppy’s loss of appetite. The diagnosis of anorexia in dogs is not the same as anorexia in humans. Anorexia in dogs may be partial or complete.

  • It’s partial anorexia if the dog eats those amounts of food but not enough to remain healthy.
  • It’s partial anorexia if the dog eats those amounts of food but not enough to remain healthy.
  • It’s partial anorexia if the dog eats those amounts of food but not enough to remain healthy.

Some healthy habits, according to one animal researcher, help animals deal with their disease. It’s essential to encourage rather than push dogs to do something they don’t want to do, such as fasting. In cases where a dog’s gastrointestinal system is the issue, not eating can help the dog’s health.

Recall When Did Your Dog Last Eat?

When your dog is not feeding, you’ll know right away. Even if you have a clear memory, make a note of when you first thought your dog wasn’t feeding. If your dog is ill, you shouldn’t be concerned for the first 48 hours until your dog has shown other symptoms.

There could be more severe issues if the pet has been vomiting or has diarrhea for days and suddenly refuses to eat. In this scenario, you would see a veterinarian as soon as possible.

Dog Appetite Loss: What Causes It?

The list of causes for a dog’s lack of appetite is lengthy. Below are a few common reasons.

1.   Dog Food

Examine your dog’s meal if the dog seems to be in good shape, and the fact that he isn’t feeding is the only thing that concerns you. The issue maybe with the food itself. It’s common for certain dogs to hate the new diet if you change their dog food. Any dogs would fail to eat the meal.

Examine the dog food’s look and smell it. There may be problems with the dog food rather than the dog. Giving your dog a fresh supply of dog food can solve the problem in this situation.

If you can’t figure out what’s behind your dog’s sudden fear of food, contact your veterinarian. When it comes to your dog’s welfare, it’s always best to be careful than sorry.

Contaminated Food

If the food has a problem, likely, your dog won’t eat. It may be rusty or spoiled or contaminated with bacteria or fungi. It’s conceivable that it may taint with toxic or foul-tasting chemicals.

2.   Examine their body

If you realize your dog’s teeth, lose or bad, or if his gums are inflamed, this may be the reason he isn’t eating. Look for parasites, changes in your pet’s hair and clothing, and any lumps or bruises while inspecting their body. If you come across something strange, don’t hesitate to call a veterinarian.

3.   Stress

Your dog can be affected by a shift in schedule. Dogs like routine, and if it disrupts, they will get agitated and avoid feeding. Changing homes, having a break, or welcoming a new family member are also examples of changes.

Changes in the feeding schedule, as previously discussed, will cause your dog to become agitated.

Some Useful Tips:

  • If you make some improvements, attempt to do so gradually so that your dogs do not feel threatened.
  • If you’re getting a new puppy, feed him the same diet he’s used to eating. Then you can alternate between old and new foods daily.
  • Every day, you should feed your dog at the same time. If you’re too busy to care for your cat, try finding a sitter or purchasing a dog feeder.
  • You should bring his belongings with you on holiday. He’ll relax a little more while he’s in his familiar bed with his favorite toys.

4.   Check Dog Behavior

Examine the dog’s actions to see whether he refuses to consume something or just certain types of food. You will use Pet cube to keep a record of your pet’s food intake even though you are not at home.

Check to see if the dog is acting normally or any other improvements in the everyday routine. Pay heed to the dog’s feces and urine as well. If all seems to be normal, you can allow your pet to miss a meal or two. Consult a veterinarian whether the dog is sick, has diarrhea, is lethargic, or is dehydrated.

5.   Check the Environment

It may be possible that your dog stops feeding when he ate something he shouldn’t have. Examine your houseplants, carpets, pet toys, and all other things in your home that your dog companion has access to. If your dog has access to drugs or toxins, be extra cautious. Consult a veterinarian straight away if something is wrong and the dog is sick or has diarrhea.

If your puppy or new dog refuses to feed, it may be due to climate change. It’s the same if you’ve recently relocated. Find out that someone has already provided your dog if you’re pet has spent time with other people during the day.

6.   Separation Anxiety

Is your dog refusing to feed while you leave him alone at home? Separation anxiety may be one of the causes. If your pet becomes agitated when left alone, you can hear about separation anxiety treatments. Another explanation may be that the dog may like to keep an eye on the house before you return. As a result, there is no time to eat. Of course, it’s likely that your dog isn’t used to feeding when left alone at home — or that your absence makes him unhappy.

Some useful tips:

  • You should increase the amount of time you spend with your puppy. The most common cause of distress in dogs is isolation from their owner(s) for an extended period.
  • Besides, please provide them with some privacy away from other people and noisy sounds.
  • More socialization is needed. It’s possible that your dog is terrified because he was never fully exposed to the world. If you don’t start socializing your dog early on, it would be more difficult for him to get along with other people and animals later.

7.   Diet

Have you seen any recent dietary modifications for your dog? Your dog does not like what you’re serving now if you changed foods. Finally, even if you’ve never changed your dog’s nutrition in a long time, this might be an issue. Moreover, if a dog eats the same thing once a day for months, it will get obsessed with it.

8.   Medical condition

The following medical conditions will cause a lack of appetite in dogs:

  • Tumors
  • Parasites
  • Depression
  • Infection
  • Pain
  • Poisoning
  • Allergies

Canine Appetite Loss Treatment

1.   Wait

If your dog refuses to feed, the first thing you can do is give them some time. Dogs are capable of going for days without food. Only make sure they’re getting enough water. It is common for a dog to refuse a meal now and then. Dogs, like humans, do not necessarily need to eat. You could put your dog’s food out to graze on when they get hungry during the day.

2.   Hunger Stimulants

We know that flavor declines with age in humans and that nothing tastes well to people who are undergoing cancer care. Our canine friends may be in the same boat. When your dog refuses to feed, you can see your doctor and find out what’s wrong and how to remedy it.

If the root problem is going to take some time to overcome, an appetite stimulant could be necessary to help your dog get back on track.

3.   Grass

If your dog refuses to eat its regular food but insists on eating grass, you should let them. It’s possible that eating grass can make your dog vomit, which might be a good thing.

Your dog’s impulses could be causing it to eat grass if whatever is making him sick can be relieved by vomiting. However, make sure the dog is hydrated.

And, if your dog vomits more than twice or eats grass any time it goes outside, you can take him to the veterinarian.

4.   Change Brand

If you’re having trouble convincing your dog to eat dry food, try a different brand. Try a demo pack at the local pet shop to see if your dog prefers a new model to the one you’ve been using. Alternatively, you might add some wet food to the mix, which can pique your dog’s interest more than the dry food.

5.   Use of Syringe

Force-feeding with a syringe is a more aggressive measure and can only use after the other options have failed. If your canine has not really ate in couple of days, try feeding it drinks like broth or watered-down wet food with a syringe.

Before doing anything, we suggest consulting with or meeting with a veterinarian since it must perform correctly or the pet’s wellbeing should jeopardize.

6.   Hand feeding

Try hand-feeding your dog bits of his or her food. It will support a dog that isn’t feeling good by soothing him and encouraging him to feed.

This method can take some time to complete, but once you’ve hand-fed your dog a couple of bits, they can start eating out of their bowl.

7.   Visit the Vet

When your dog is ill and won’t feed, it’s a bright idea to take him to the vet. A veterinarian will assist you with determining what is wrong with your dog and what you can do to make them feel better.

A veterinarian will also ensure that your dog has whatever medicine it requires, whether to treat the disease or to stimulate appetite.

When to Feed a Sick Dog?

You must start feeding your pet once at least 12 hours since the last event whether your dog has been ill or has diarrhoea. If you provide your dog too quickly after vomiting, the food will upset its stomach again, causing it to vomit even more.

Take the dog to the clinic if the vomiting or diarrhea lasts longer than two days.


You might find your dog isn’t eating at any stage during his or her life. This conduct may be due to a variety of factors. Whatever is forcing your dog to refuse food, you must take him to the veterinarian to determine the source of the issue and re-establish his appetite. Only a veterinarian will adequately assess the problem and restore the dog’s wellbeing.

Finally, what you have to do is follow the vet’s recommendations. If your dog needs medicine to rekindle his appetite, give it to him. Offer him some TLC if he wants some time with you to be okay. Remember that your dog requires your attention just as much as he needs food.
