Food is essential for the survival of all living beings.
Without it, everyone would become ill, and they would all pass away.
Your dog is not an exception; to maintain its health and strength, he must consume an adequate and well-balanced diet.
But what do you do if your dog refuses to take his food at the times when he should take food?
The first and most important to say is: don’t worry too much!
Dogs can go for extended periods without eating.
In the meantime, you have a lot of reading to educate yourself on the possible reasons why they are not eating and what you can do to assist your ideal pet in quickly regaining their appetite.
How Long Can A Healthy Dog Go Without Eating?
There isn’t a clear answer to the question.
Some veterinarians answer to the question “how long can a dog go without eating” is: five days for most healthy dogs, while others say up to 10 days.
Remember that only healthy dogs are eligible for this and drink the recommended amount of water daily.
When dogs raise their resting metabolic rate (RMR), just like humans, their calorie requirements increase.
The length of time a dog may go without eating is determined by several factors, including any pre-existing medical concerns, the amount of water they are drinking, the weather, and the amount of exercise they get.
How Long Can A Sick Dog Go Without Eating?
Have you ever been so sick that the smell of food made you want to throw up?
When a dog is ill, he will frequently cease eating to aid in its speedy recovery; the less energy spent on digesting food, the more power can battle the sickness.
Even if this is helpful for your sick dogs, it is still something that you should keep an eye on.
If you go more than two days without eating, the situation may get even direr.
In 2015, the American Academy of Veterinary Nutrition conducted research in which they looked at the diets of 490 dogs who had been hospitalized for just one day.
They discovered that dogs who consumed an adequate amount of eating food to satisfy their requirements for resting energy had a greater chance of being released alive.
Those who didn’t were not as fortunate as those who did.
Is It Normal For A Dog To Go Without Eating For A Specific Time?
Yes, it is!
When dogs still drink water and are generally healthy, they can handle being without eating for a while.
However, contact the vet after 48 hours or if your dog shows other symptoms.
No defined number of days is “safe” for dogs on hunger strike, but most healthy dogs may survive at least three days without food if they drink water.
When your dog refuses to eat, their appetite loss is more significant.
Changes in appetites can be substantial, so if in doubt, visit your vet.
Reasons Why A Dog Won’t Eat / Wants To Be Without It
There can be as many reasons as you think, but the primary reasons behind eating issues are as follows:
He Has Medical Conditions
Reduced dog’s appetite or refusing food could indicate medical conditions like kidney problems, liver problems, diabetes, inflammation (viral or bacterial), fever, cancer, the proportion of respondents (womb infection), pain all over the body, gastroenteritis, etc.
Your Dog Has A Dental Problem (Medical Conditions)
Your dog may not eat if he has tooth decay, gingivitis, a fractured tooth, an abscess, or an oral tumor.
Your vet will check your dog’s mouth at their clinical exam for concerns.
There’s A Change In Food
Your dog’s change in eating habits may also be due to the ingredients in the dog food they usually eat having been changed.
The vet suggests that you don’t always feed your dog the same type of food to avoid this problem.
The (Wrong) Time Of Day
Some dogs eat at set times.
Your dog may only eat at noon or after dark.
Irrespective of your dog’s preferences, feeding them at the same time daily is standard.
If they eat once a day, don’t worry.
Your Dog Is Picky
If your dog refuses particular foods, nothing is significantly wrong.
Your dog could be a picky eater.
This condition is more common in dogs fed a range of foods, table scraps, or inconsistently.
Is your dog currently taking medication?
That drug and/or routine change could be causing stomach upset.
Trigger: Social Issue
A new environment, person, or pet can distress your dog.
Environmental changes may cause dogs to stop eating.
Then they may lose appetite.
Separation anxiety and dread are others.
You Feed Bad Or Contaminated Food
Your dog eating treats but not food may indicate that the food you’re feeding is terrible.
If the food isn’t good, dogs stop eating.
If your dog suddenly stops eating a particular brand they’ve been used to eating for years, it may be spoilt.
Old food could contain substances that are either toxic or unpleasant to taste.
It’s stale, moldy, or infected with harmful microorganisms.
The Mental Health / Emotional Trigger
Dogs might stop eating when a move or other significant environmental change is stressed.
Your dog may become anxious when introduced to a new environment or a new human or canine family member.
Until they calm down, they might not feel like eating.
Fear of being left alone is another potential reason.
What Should You Do If Your Dog Doesn’t Eat
Most Important: No Panic
Being a dog owner, you should remember that dogs can go without food for short periods without any long-term problems.
That answers the question “how long can a dog go without eating”?
A one- or two-day fast isn’t a big deal as long as your dog usually behaves and doesn’t show signs of illness.
Second Step: Try To Find Out The Reason For Your Dog Not Eating
Look at the label on every medication your dog has taken, look at the food your dog is eating, and think about your recent daily activities.
Your dog may be able to regain appetite if you really can figure out the reason he stopped eating in the first instance.
This May Help: Get Your Dog’s Favorite Food
Investigating whether your pet’s refusal to eat is due to pickiness or other issues is often worthwhile.
First, try providing your pet with healthier versions of her favorite foods, such as canned food or semi-moist dog food, a carrots stick (for dogs), boiling chicken or hamburgers, salmon, etc.
Wet food with a meat flavor is bland but tasty and works well to stimulate a pet’s appetite.
The best way to get your dog to eat depends on the situation, but it could be switching his food or giving him some treats he likes.
So see if he’ll eat a meat slice or two, a piece of cheese, or some cooked chicken.
If he quickly consumes them, it indicates that food-related issues may be at the root of the problem and that dog’s appetite is here.
Try Him To Go Without Eating For 48 Hours
To figure out if something is wrong with your dog, make him fast for 48 hours.
Then, if your dog still refuses to eat after those two days, contact your veterinarian for advice.
Of course, this strategy assumes your dog is healthy and not displaying any concerning medical symptoms.
If you suspect your dog is ill for any reason, contact your veterinarian right away.
How Long Should You Wait Until You Contact Your Vet / Vet Clinic When Your Dog Stops Eating?

If you notice any of those symptoms and your dog is not eating, always contact your vet immediately!
What Do Vets Do For A Dog Who Won’t Eat?
Expect your vet to complete your dog’s physical examination during your appointment.
He’ll want to ensure your dog isn’t showing any severe undernutrition or dehydration.
The physical exam will also assist your veterinarian in determining why your dog isn’t eating.
If your vet’s physical examination does not reveal a likely cause, he will likely recommend additional tests for your dog.
X-rays to rule out pain or injuries, urinalysis, and blood tests are all possible tests.
He may also recommend these tests to confirm a suspected diagnosis based on the physical exam.
With just about any luck, your vet would be capable of determining why the problem is happening and suggest a good way to fix it.
If your dog has a severe illness or doesn’t start eating on its own, your vet may give it a feeding tube.
By doing this, the vet’s staff can ensure that their dog gets enough food while they figure out and resolve the issue.
How To Get A Dog To Eat And Drink
After answering the question “how long can a dog go without eating?”, you want to know how you can motivate your dog to eat and drink.
Making your dog’s food or water more appetizing is one strategy for getting your dog to consume it.

You could try putting some beef or chicken broth in your dog’s water.
Adding a flavoring to the water can encourage your dog to drink more.
Add some seasoning to your dog’s food to improve its flavor.
Keep your dog off fatty treats and think about mixing in some boneless, skinless chicken breast instead.
