Why Dogs Skipping a Meal (or two) Isn’t a Big Deal

When your dog suddenly loses their appetite, it can be cause for alarm. But, trust me, not only is your dog skipping a meal (or two) safe, it can be downright essential for promoting good health.

Why is it okay for your dog to skip a meal?  Simply put, the energy your dog would have spent digesting food is free to repair their body and strengthen their immune system. Fasting is only recommended for adult dogs (1+ years), on a balanced raw food diet, and for no longer than 48 hours.  

For a Dog, Skipping Meals is in Their DNA

The term “Wild Health” was coined by Dr. Barbara Royal, author of The Royal Treatment*. It’s a holistic approach to animal care with the guiding principle an animal’s behavior in its natural habitat should guide the health decisions we make for our pets at home.

*SIDE NOTE: If you’re curious about raw feeding, The Royal Treatment is a great place to start. Here is an Amazon link to the book.

So, how does “Wild Health” apply to your dog? – your fluffball Pomeranian is as far from “wild” as it gets, right?

Well, it’s true the modern dog is the most successfully domesticated animal in human history. But, your little fluffball still shares 98.8% of its genetic makeup with the gray wolf.

In fact, dogs and wolves can mate and birth fertile puppies (e.g. puppies who will also be able to reproduce someday). That’s a big deal. Different species of elephants can’t do that.

So, as the theory goes, the eating habits of the gray wolf is indicative of the optimal eating habits of your dog. Wolves are scavenging carnivores who eat when they can get it – not on a tight two-a-day schedule. One day they may feast on deer and two days later they may get lucky and nab a tasty rabbit.

Regularly Scheduling Meals is a Human Construct We Impose on our Dogs

At this point, you may be thinking, “So, just because wolves do it my dog has to too?” Like, if all the wolves jumped off of a bridge, blah blah blah.

Even though our dogs look wildly different from their wild counterparts, they still share a stunningly similar digestive system. And, Mother Nature tends to know what’s best for its animals, including dogs.

Dogs, like us, generate their cellular energy from mitochondria, often regarded as the “powerhouse” of any animal body. Mitochondria is responsible for every movement we make, whether it’s voluntary, like moving your hand, or involuntary, like a heart circulating blood through the body.

Converting food into energy is a huge endeavor for the body. This is partly why we tend to feel so tired after eating a huge meal. And because of the resources it takes, the body often has to sacrifice other functions, like self-repair, in order to meet the energy demands of digesting food

Imagine for a second the body as an automobile – the gas represents food, which is meant to make the car move. What if the car has to move whenever there’s gas in the tank? How much more difficult is an oil change when the car is moving? How much more dangerous is it when the engine is running?

Luckily, we can turn the keys and shut off a car. That’s not the case with you or your dog.

By regularly fasting your dog, you are allowing its body to shed and produce new mitochondria, strengthen its immune system, so she/he can more effectively heal and ward off infection & disease.

Should You Intentionally Fast a Dog?

I have three adult dogs, all over a year old – and I make it a habit to fast them one day a week. This means each of my dogs skips two consecutive meals once a week – usually on the weekends when I have more time to distract them.

First, I wouldn’t recommend skipping meals for a puppy under one year. Puppies are notoriously hungry for a reason, and the chemical reactions in their bodies are all pointed towards growth. Growing body mass requires a lot of food at this stage of their life, so it’s not a good idea to deny them any.

Next, I solemnly believe in feeding my dogs a raw diet. For those unfamiliar with the term, it goes back to the “Wild Health” philosophy I mentioned earlier in the article. I feed my dogs as close a possible to what they would eat in the wild – high amounts of raw animal protein, moderate amounts of healthy fats, some veggies, and minimal grains and carbohydrates.

What does a raw diet have to do with your dog skipping meals?

1 – A raw diet contains a moderate amount of healthy fat – and dogs are well equipped to use this fat as an energy source for long periods of time. So while they may be hungry the first few hours I fast them, their body quickly gets with the program and taps into those energy reserves.

2 – Dry kibble contains a high amount of carbohydrates derived from grains – which dogs are ill-equipped to use as an energy resource. If your dog eats dry kibble, they’re going to burn through those carbohydrates in a just a few hours, and come looking for you to put down the food bowl for their next energy fix.

If your dog is currently eating kibble – I strongly recommend going a) raw and b) not forcing her/him to skip meals. All it will do is make them really cranky and potentially cause long-term behavioral issues.

However, if your dog doesn’t feel like eating when you put down the bowl – great! Don’t force it on him/her, but allow them to decide what’s right for their body, and when they need extra energy to heal.

Last, if this type of fasting all sounds vaguely familiar to you, then you’re probably thinking of intermittent fasting – which is sweeping the United States at the moment.

Intermittent fasting yields just as many positive effects for the human body as it does for your dog. Learn more at the Keto Kamp Youtube Channel for more information on fasting your dog:

If My Dog Skips a Meal, Should I Double the Proportions of the Next Meal?

Personally, I never double proportions – but rather add 1.5 times what they would’ve originally eaten. I do this for a couple of reasons:

  1. Your dog’s stomach will shrink, especially if they skip two meals. If you give them two to four times a regular meal, you’re just asking for them to puke all over your new sofa.
  2. Let’s go back to the automobile analogy – if your dog’s body is the equivalent of a car, then the more fuel you put into it the more mileage you’ll put onto it. The more calories you put into your dog the more…mileage you put onto her/him? Okay, the metaphor is sticky, but you get the idea.

Last, if my dogs miss one meal – I add 1.5 times to the next meal. If my dog misses two meals – I add 1.5 times to the next two meals. I don’t have any science to back it up – it just feels right.

When Should I Be Concerned About My Dog’s Loss of Appetite?

My dogs are my family – and there is no amount of debt I wouldn’t take on to make sure they’re living healthy, happy lives. But, I do believe we’ve been culturally programmed to rush to the veterinarian at the drop of a hat.

Yes, I get it, they can’t talk…

But, if something is truly wrong with your dog, you will see signs, such as:

  • Blood in the stool
  • A drastic change in behavior – especially aggression
  • Unrestefullness – they constantly look in pain
  • Uncontrollable vomiting
  • Not drinking water
  • White gums (which could also be dehydration)

If your dog skips two, even three meals, and there are none of the above signs, perhaps they’re fighting off an infection. Let their bodies do what they were designed to do.

After the third meal, I’d call my vet to let them know what’s going on. You can schedule a preliminary appointment for the next morning.

If your dog goes two full days without eating – something is probably up. Never force food on them, but at a certain point, hop into the car. It’s time to go to the vet.

How Long Can My Dog Go Without Eating?

And, just in case you’re curious, a dog can go up to five days without food before it will begin to experience serious problems, like kidney failure.

But, of course, we won’t be letting it get that far, right?

Happy fasting!
