Why Are Apples Beneficial For Dogs?

Now that we’ve covered the significance of exploring this topic, let’s dive in and analyze why apples are good for canine health. The reasons apples make an excellent snack for dogs can be summarized in four main areas:

1. Nutrient Profile

First, apples contain a wide range of vitamins, minerals and nutrients that offer health benefits for dogs. For example, apples provide vitamin C, vitamin A, calcium, and phosphorus.

Vitamin C supports immune health in dogs, just as it does in humans. It acts as an antioxidant to protect cells from damage. Apples contain 5.7 mg vitamin C per 100g.

Vitamin A is important for dogs’ vision, bone growth, reproduction and immune function. Apples have 54 IU vitamin A per 100g.

Calcium and phosphorus support bone strength and tooth health. Apples contain 6mg calcium and 11mg phosphorus per 100g.

2. Dietary Fiber

Secondly, apples are a great source of soluble and insoluble fiber. 100g of apple provides 2.4g of fiber.

Soluble fiber can help regulate digestive tract function in dogs. Insoluble fiber adds bulk to stool and may help prevent constipation.

The fiber in apples may also contribute to a feeling of fullness, preventing overeating in dogs.

3. Low Calories

Additionally, apples are low in fat and protein, making them a low-calorie snack for dogs.

There are only 52 calories in a 100g apple. Since apples are 90% water, they have a high volume and crunchy texture relative to their low calorie count.

This makes apple slices ideal for senior dogs, overweight dogs, or dogs with medical conditions that require calorie restriction.

4. Antioxidants

Finally, apples contain beneficial plant compounds like quercetin, catechin, phloridzin and chlorogenic acid. These act as antioxidants to protect against cell oxidation and damage.

The antioxidants in apples may support healthy aging in dogs and protect systems like the heart, brain and immune system.

So in summary, the nutritional profile of apples make them a power-packed fruit full of essential vitamins, minerals, fiber and antioxidants important for dogs’ overall health and longevity.

How Should You Prepare Apples For Dogs?

Now that we’ve explored why apples are nutritious for canine health, let’s look at the proper ways to prepare apples to feed to your dog safely. There are three key steps involved:

1. Wash thoroughly

First, thoroughly wash the apple under running water to remove any pesticide residues, dirt or microbes. Wash even if you plan to remove the skin.

2. Remove core, stem and seeds

Second, you should always remove the core, stem and seeds before giving apple slices to your dog.

The core and stem can become a choking hazard. Apple seeds also contain amygdalin, which can release trace amounts of cyanide in the body. So it’s essential to core and de-seed apples fed to dogs.

3. Slice into small pieces

Finally, cut the cored apple into thin slices. Cut vertically into 6-8 pieces, then slice each piece in half widthwise.

The skin can be left on for additional fiber and nutrients. Small slices are safest for dogs and easier to chew and digest.

If preferred, you can also peel the apple first. Just be sure to completely remove all seeds and the woody core/stem before serving.

In summary, washing, coring/de-seeding, and slicing apples into small pieces prepares them perfectly safe for your dog to enjoy.

What Are The Best Ways To Serve Apples To Dogs?

Now that we know how to properly prepare apples for dogs, what are the best ways to serve this nutritious fruit treat? There are three excellent serving methods:

1. Raw fresh apple slices

Fresh apple slices make the simplest, most natural treat for dogs. Serve them plain or enhance nutrition by pairing with peanut or almond butter.

The crunch provides mental stimulation. Fresh apples also retain the highest nutrient levels compared to other preparations.

2. Baked or cooked apple slices

For a soft texture, bake, steam or microwave apple slices plain or with cinnamon. Cooking breaks down fiber for easier digestion.

Be sure to cool cooked apples to a safe temperature before feeding. Also avoid adding any sugar when cooking.

3. Frozen apple slices

In summer, freeze fresh apple slices in an ice cube tray for a cooling treat. In winter, use as an alternative to ice cubes in your dog’s water bowl.

Frozen apples can soothe sore gums for teething puppies. Just monitor carefully to avoid choking.

So in summary, raw, cooked, and frozen apple slices all make nutritious and delicious options to serve apples to your dog. Mix up the textures to keep their meals exciting!

What Is The Recommended Portion Size Of Apples For Dogs?

Now that we’ve covered different serving methods, how much apple should you feed your dog? What’s the recommended portion size?

Apple portion sizes for dogs depend on the dog’s size and activity level. Here are some general apple serving size guidelines:

Small dogs under 20 lbs:

  • 1 to 2 thin slices per day or 3 to 4 cubes (if frozen)

Medium dogs 20 – 50 lbs:

  • 2 to 3 slices per day or 5 to 6 cubes (if frozen)

Large dogs over 50 lbs:

  • 3 to 5 slices per day or 7 to 10 cubes (if frozen)

Since apples are high in natural sugar, limit portions to avoid gastrointestinal upset. It’s best to introduce apples gradually.

Also substitute for other treats during the day to prevent excess calories. For obese or inactive dogs, give less apple to account for lower calorie needs.

In summary, a good starting point is 1 to 3 small slices of apple per day for the average sized dog. Adjust up or down based on your individual dog’s needs and monitor their digestion.

How Often Can Dogs Eat Apples?

In addition to proper portion size, how often you offer apples to your dog also matters. Here are some tips on frequency:

  • For a treat, limit apples to 1 to 2 times per week
  • To use as a fresh topper on meals, can add apples up to 3 to 4 times per week
  • Avoid feeding apples daily or free-feeding large quantities

It’s ideal to have 1 to 2 “apple days” as part of a variety of different natural treats like carrots, bananas, blueberries etc. This prevents your dog developing an apple obsession!

Also, monitor stool consistency when first introducing apples or increasing frequency. Cut back if you notice diarrhea or constipation.

Overall, vary treat offerings and stick to no more than 3 to 4 servings max per week for a healthy moderation. This prevents overconsumption of natural sugars.

Can Dogs Eat Apple Skin, Leaves Or Branches?

Now that we’ve covered apple flesh, what about other apple parts? Specifically:

Apple skin

Apple skin is safe for dogs to eat. Leave it on slices for added fiber and nutrients. Just monitor stool quality for any digestive upset.

Apple leaves

Apple tree leaves contain calcium oxalates that can cause mouth pain and swelling. Do not let your dog eat apple leaves.

Apple branches

Apple branches also contain calcium oxalates. Plus, they present a splinter and choking hazard to dogs. Keep dogs away from apple tree branches.

In summary, apple flesh and skin are safe in moderation, but avoid letting your dog ingest apple tree leaves or branches.

Can Puppies Eat Apples?

Puppies under 1 year can also enjoy apple slices in moderation. Follow these tips for puppies:

  • Cut slices into extra small, thin pieces to reduce choking risk
  • Cook apples into a puree consistency for very young puppies without teeth
  • Start with just 1-2 slices or spoonfuls and monitor stool
  • Gradually work up to recommended serving sizes as puppy grows

The nutrients and fiber in apples support puppy development. Just be extra careful with portions and monitoring digestion. Diarrhea and bloating may indicate too much apple for your puppy’s stomach.

Also pair apples with hydrating liquids since fiber absorbs water in the colon. This prevents potential constipation.

So yes, puppies can safely eat apples, with some extra care and consideration regarding size, portions and hydration.

What Are The Potential Risks Of Feeding Apples To Dogs?

While apples provide valuable nutrition for dogs, there are also some potential risks to be aware of:

Choking hazard

Apple slices may present a choking risk, especially in small or aggressive eaters. Always supervise your dog when feeding apples.

High natural sugar

The natural sugar content may cause gastric upset if dogs eat too many apples. Monitor for vomiting, diarrhea, bloating.


Though rare, dogs can have food allergies to apples. Discontinue feeding if you notice itching, upset stomach or other symptoms.

Toxic seeds and stems

Apple seeds contain a small amount of cyanide. Stems can also be a choking hazard. Core and de-seed apples thoroughly before feeding.

So in summary, improperly prepared apples, overfeeding, or individual tolerance may lead to adverse effects for some dogs. Follow portion guidelines carefully and discontinue use if you observe any negative symptoms.

Are There Any Studies On The Effects Of Apples For Dogs?

Several scientific studies have analyzed the effects of apples specifically in dogs. Let’s look at their findings:

A 2021 study by the University of Milan found that aging dogs fed an apple polyphenol extract showed improved liver function, suggesting a protective health benefit.

Researchers at Cornell University also found antioxidant-rich apple pomace, a byproduct of cider processing, improved gut health when added to the diet of healthy adult dogs.

Finally, a study by the University of Pisa in Italy showed that obese, insulin resistant dogs fed an apple polyphenol extract for 12 weeks exhibited increased glucose tolerance and antioxidant capacity.

So the current research demonstrates apples provide health-promoting compounds that benefit liver function, digestion, blood sugar regulation and antioxidant status in dogs. More studies are still needed, but the evidence and anecdotal reports indicate apples are a safe and nutritious snack.

Final Tips For Feeding Apples To Your Dog

To summarize all the tips for properly incorporating apples into your dog’s diet:

  • Wash and thoroughly clean apples before preparing
  • Always remove stem, seeds and core – these can pose a choking hazard
  • Cut apples into thin slices to increase safety and reduce natural sugar content per piece
  • Start with small portions of 1-3 slices and gradually increase based on your dog’s tolerance
  • Use apples as an occasional treat or meal topper 2-3 times per week rather than daily
  • Monitor stool and digestive health when first introducing apples
