Can Dogs Eat Apple Cores? Toxic Seeds?

can_dogs_eat_apple_cores

 

Can dogs eat apple cores? Not really. Apple cores can be a choking hazard to dogs. The core contains the seeds which contain cyanide. If cyanide is consumed in large enough quantities, this can be poisonous to dogs.
Giving your dog the skin and flesh, however, are perfectly healthy and a tasty treat for dogs. Apple has many nutritional benefits, including containing antioxidants, which are thought to help prevent cancer and diabetes, as well as helping with weight loss and heart health.

 

Quick Apple Questions: 

What should I do if my dog ate an apple core?
It depends on the amount. If it was only one core is unlikely to harm your dog. It is thought to take a considerable amount of seeds to cause toxicity. 
If your dog is behaving strangely or is experiencing vomiting and diarrhea, contact your veterinarian for advice.

 

Can an apple core kill a dog?
One core is unlikely to cause death. The amount of toxin in the seeds is so minimal. It would take a considerable amount of seeds to cause harm in most dogs. 
The main risk would be from choking as dogs do not chew their food as we do.

 

Can dogs eat apples skin?
Yes, the majority of the time the skin is perfectly safe to eat and is even beneficial. It can occasionally cause a bit of gastric upset (loose stools or vomiting) if consumed in a large amount.

 

How much apple can I give my dog?
It varies from dog to dog, spending on weight, size, breed, and activity level. We would recommend starting with just a slice to see if your dog enjoys it. If this has no adverse effect on your dogs' stomach, you can increase from there.
Remember to introduce new foods slowly; any drastic change in diet can cause vomiting and diarrhea. 
Treats and complimentary dog food should only make up 10% of your dogs' diet. So make sure not to overfeed your dog, even with healthy fruits and vegetables. Excess food can lead to weight gain and weight-related health issues as well as excess sugar in fruit, causing dental and behavioral issues.

Benefits Of Apples

apples_on_tree

 

'An apple a day keeps the doctor away.'  

Cheap and Easy To Find

Apples are affordable and easy to buy in the grocery store or at a farmers market. If you are looking for a cheap treat for your dog, apples are a great option.
They can be dehydrated, frozen, pureed, made into apple sauce, baked into biscuits, and added to dog food.

 

Promote Weight Loss

Apples are a low-calorie snack that can be used as a healthy training treat. As well as being healthy, studies have also shown that apples may help regulate gut bacteria, which can help in reducing obesity (link).

 

Help Regulate Diabetes

Apples are relatively low in the glycemic index despite containing carbohydrates. 
This is due to the amount of fiber. The fiber helps to balance out the digestion of carbohydrates and doesn't cause the blood sugar to spike so rapidly.

 

May Prevent Cancer

Apples contain the antioxidant polyphenols, which are thought to have cancer-preventing properties (link) (link).

 

Improve Digestion

The fiber content in apples is excellent for digestion. Fiber will help keep your dog regular and keep the gastrointestinal system healthy. This will also help prevent constipation and help with preventing diseases such as IBS and colitis.

 

Risk Of Apples

apple_seeds

Choking 

Most dogs do limited chewing and just swallow their food. Due to the shape and size of apples, they can cause a blockage. We recommend cutting the apple into bite-sized chunks to limit the risk of choking. 
It is also best not to feed your dog the core or any seeds, as this could also be a choking risk.

 

Cyanide Toxicity 

The seeds of the apple contain a small amount of cyanide. If consumed in a large quantity, they can be dangerous to dogs. If your dog has only eaten 1 apple, including seeds, they should be fine.
It is thought to be rare that a dog would get cyanide poisoning as they would need to chew to release the toxin in the seeds. Due to the size of the seeds, the majority of the time, they are swallowed. 
Symptoms Of Cyanide Poisoning In Dogs
According to the ASPCA, symptoms include:
  • Dilated pupils
  • Difficulty breathing
  • Bright red gum color
  • Shock 
  • Death

 

Gastric Upset

All new foods can cause gastric upset, including vomiting and diarrhea. Introduce new foods slowly and in small portions to limit the risk of causing this. 
An apple also contains around 5g fiber. This can be great for improving digestion, but if your dog has a sensitive stomach or is not used to this, it can cause diarrhea. 

 

Added Ingredients

If you are feeding your dog apple in the form of applesauce, apple pie, apple crumble, apple salad, or in any other recipe, the added ingredients can be toxic for dogs. 
We recommend making dog-safe treats rather than using human ones.
If you are going to be feeding your dog premade foods, check the ingredients for common toxins (xylitol, grapes, raisins, some nuts, onion, garlic), salt, and sugar levels.

 

Fermented or Rotten 

Fermented or moldy apples can pose a risk of alcohol toxicity. Symptoms are similar to those in humans, including lethargy, stumbling, inability to stand, vomiting, etc (link)

 

Is Apple Sauce Good For Dogs?

apple_sauce

It depends on the ingredients. Most store-bought apple sauces contain unhealthy or unsafe ingredients, as well as high amounts of sugar.
If you are looking to buy apple sauce for your dog, make sure to avoid varieties with excess sugar, xylitol, and nutmeg. All of these can be dangerous to dogs.
We prefer to make our own. Our favorite recipe is this one inspired by Sugar The Golden Retriever.
Ingredients:
  • 4 apples

  • 2/3 cup water

Check out our article Can Dogs Eat Apricots for more information. 
Bananas - Yes, bananas are an excellent low-calorie treat. They are high in potassium, as well as other vitamins. They also work well to bind ingredients together in dog treats. Only feed bananas in little amounts as they do contain a considerable amount of sugar.
