Can Apples Give Dogs Diarrhea? The Surprising Truth Every Pet Parent Should Know

September 29, 2025 |

Apples! Theyre delicious and nutritious for humans, but can your dog eat them? Here’s what you need to know.

Apples are a great source of vitamins and minerals, and they also contain dietary fiber that helps keep the digestive tract in check.

Apples can be a delicious snack for your pup, but one part of the apple should be kept off-limits — the tough center known as the core. The core is a choking hazard, and the seeds embedded in the core contain traces of cyanide (which can be dangerous for your dog!)

Read on to learn more about the many benefits of apples for your dog, how to prepare an apple to serve safely to your pup, and other fruits that can support your dog’s overall health.

Have you ever shared a crisp apple slice with your furry friend only to be cleaning up a mess later? As a dog owner myself I’ve wondered about this exact situation. Many pet parents ask does apple give dogs diarrhea? The short answer is yes, it can – but there’s much more to understand about this common fruit and your pup’s digestive system.

The Truth About Apples and Dog Digestion

Apples are generally safe for dogs and even offer some health benefits. However, they can cause digestive issues including diarrhea in some situations Let’s break down what you need to know

Why Apples Might Cause Diarrhea in Dogs

There are several reasons why your dog might experience tummy troubles after munching on apples:

  1. High Fiber Content Apples contain both soluble and insoluble fiber that can promote bowel movements, potentially leading to loose stools if consumed in excess.

  2. Natural Sugars: Dogs may have trouble digesting the fructose in apples, which can create an imbalance of gut bacteria.

  3. Too Much Too Soon: Introducing apples suddenly to a dog who’s never had them before can trigger digestive upset.

  4. Apple Seeds and Cores: These contain small amounts of cyanide compounds that can be toxic and cause gastrointestinal distress.

  5. Pesticides: Store-bought apples may contain pesticide residues that could trigger sensitivity or allergic reactions.

The Science Behind Apple-Related Digestive Issues

When a dog eats too many apples, their digestive system can become overwhelmed. The high fiber content in apples acts as a natural laxative. While this is beneficial in small amounts, excessive consumption can speed up digestion and result in diarrhea.

Additionally, some dogs simply have more sensitive stomachs than others. Just like humans, dogs can have individual food sensitivities that make them more prone to digestive upset when eating certain foods.

How to Safely Feed Apples to Your Dog

Despite the potential risks, apples can be a healthy treat for most dogs when given properly. Here’s how to do it safely:

Proper Apple Preparation for Pups

  1. Remove the core and seeds – Always remove the apple core and seeds before giving any to your dog
  2. Wash thoroughly – Rinse apples well to remove pesticides and bacteria
  3. Consider peeling – The skin contains more fiber and potentially more pesticides
  4. Cut into small, manageable pieces – This reduces choking hazards and makes digestion easier
  5. Start with small amounts – Introduce apple gradually to see how your dog reacts

Serving Size Guidelines

Dog Size Recommended Apple Serving
Small (under 20 lbs) 1-2 small slices
Medium (20-50 lbs) 2-3 medium slices
Large (over 50 lbs) 3-4 slices maximum

Remember, treats should only make up about 10% of your dog’s daily caloric intake. Even though apples are relatively low in calories, they still count as treats!

Signs Your Dog is Having Trouble with Apples

Watch for these symptoms after giving your dog apple:

  • Loose stools or diarrhea
  • Vomiting
  • Decreased appetite
  • Abdominal pain (whining, restlessness, or a hunched posture)
  • Excessive gas
  • Lethargy

If you notice any of these signs, it’s best to stop feeding apples and consult your veterinarian if symptoms persist.

Health Benefits of Apples for Dogs

It’s not all bad news! When fed properly, apples offer several benefits:

  • Vitamin C and A: Support immune function and vision health
  • Antioxidants: Help combat cellular damage
  • Fiber: Aids digestion when given in appropriate amounts
  • Low calorie: Makes a good treat for overweight dogs
  • Dental benefits: The crunchy texture can help clean teeth (though not a substitute for dental care)

FAQs About Dogs and Apples

Can puppies eat apples?

Yes, puppies can eat apples, but start with even smaller amounts than you would for adult dogs. Their digestive systems are more sensitive, so watch them closely for any adverse reactions.

Is applesauce okay for dogs?

Yes, dogs can safely eat plain, unsweetened applesauce in moderation. This can actually be easier on their digestive system than raw apples. Avoid applesauce with added sugars or artificial sweeteners.

What should I do if my dog ate apple seeds?

Don’t panic if your dog consumes a few apple seeds. The amount of cyanide in a few seeds is unlikely to cause immediate harm. However, monitor them for any unusual symptoms and contact your vet if you’re concerned or if they ate a large quantity.

Are green apples more likely to cause diarrhea than red ones?

Green apples like Granny Smith tend to be more acidic and contain more fiber than some red varieties, potentially making them more likely to cause digestive upset in sensitive dogs.

What To Do If Your Dog Gets Diarrhea From Apples

If your dog develops diarrhea after eating apples, here’s what to do:

  1. Stop feeding apples immediately
  2. Ensure access to fresh water to prevent dehydration
  3. Consider a bland diet of boiled chicken and rice temporarily
  4. Monitor for improvement over 24-48 hours
  5. Consult your veterinarian if diarrhea persists or worsens

My Personal Experience with Dogs and Apples

I’ve had three different dogs over the years, and each one reacted differently to apples. My Labrador could eat several slices with no issues, while my sensitive Beagle would get loose stools from just a small piece. This taught me that every dog is unique, and what works for one might not work for another.

Last summer, I gave my current dog too many apple slices during a picnic, and we definitely paid for it later that night! Now I’m much more careful about portion control.

The Bottom Line on Apples and Dog Diarrhea

Apples can be a healthy, low-calorie treat for most dogs when given properly and in moderation. However, they can cause diarrhea if:

  • Fed in excessive amounts
  • The core or seeds are included
  • Your dog has a sensitive stomach
  • They’re introduced too quickly to your dog’s diet

The key is moderation and proper preparation. Start with small amounts, remove seeds and cores, and monitor your dog’s reaction. If your furry friend enjoys apples without digestive issues, they can be a great occasional treat!

Remember, when in doubt about your dog’s diet or if they experience persistent digestive problems, always consult with your veterinarian. They can provide guidance specific to your dog’s health needs and help you determine the best treats for your particular pup.

Have you experienced issues with feeding apples to your dog? Or have you found they make a perfect healthy snack? Every dog is different, so sharing experiences helps us all become better pet parents!

Rotten to the Core

Make sure to de-core the apple and remove the stem before serving it. The core is a choking hazard and is hard for your dog to digest. You’ll want to throw away apple seeds, too, since they contain traces of the toxic chemical cyanide. Even though there are only small traces of cyanide in apple seeds, it’s best to avoid them altogether so your pup doesn’t end up with an upset stomach.

If you are concerned your pup may have ingested a high volume of seeds from an apple, or any other type of fruit or vegetable containing harmful substances, contact your veterinarian or emergency clinic immediately.

Signs that your dog may have ingested a toxic substance include the following:

  • Dilated pupils
  • Difficulty breathing
  • Salivation
  • Red gums
  • Lethargy
  • Vomiting

Red or Green Apples?

The color of the apple itself doesn’t matter, but your dog may favor one over the other because of the taste.

Red apples tend to have a sweet flavor, whereas green apples are more on the sour side. You may need to experiment with your pup to determine which type of apple they prefer.
