Can Dogs Eat Oranges

You’d often see them in dog treats and even in their food. There are certain fruits that provide health benefits to the dogs. However, there are also those that are not safe for them to eat. For instance, it is common knowledge that grapes and macadamia nuts are toxic to pets; giving it to them would be something you don’t want to risk.

How about oranges? Is this fruit safe for dogs?

Our veterinarian friends from Doggypedia discuss this in detail below. After all, we just want the best for your pets and everything you need to know to make them happy can be found here. Read on to find out.

In a study published by NCBI, entitled Grape juice but not orange or grapefruit juice inhibits platelet activity in dogs and monkeys, it states that “Platelet aggregation (PA) contributes to both the development of atherosclerosis and acute platelet thrombus formation (APTF) followed by embolization producing cyclic flow reductions (CFR) in stenosed and damaged dog and human coronary arteries.”

So can our furry best friends eat oranges?

To put it simply, and to give you a direct answer to this question, it would be YES, but there are several factors to weigh in such as health issues and conditions your dogs already have.

Dogs with weight issues, diabetes or other illness, and digestive health issues should check with a veterinarian whether it is safe for them to have orange on their diet or snack/meal plan.

Orange in general are not bad for dogs. In fact, your furry pets can enjoy the health benefits they get from this citrus fruit. Orange contain Vitamin C that your dogs can make use of. It helps with their immune system really greatly. Plus, oranges also have potassium and fiber than help with the digestive track for your dogs.

In another study published by NCBI journal titled Effect of Citrus paradisi extract and juice on arterial pressure both in vitro and in vivo,  it stated, “Citrus paradisi (grapefruit) consumption is considered as beneficial and it is popularly used for the treatment of a vast array of diseases, including hypertension. In the present study, the coronary vasodilator and hypotensive effects of Citrus paradisi peel extract were assessed in the Langendorff isolated and perfused heart model and in the heart and lung dog preparation.”

Here’s a list of the health benefits of orange on your dogs’ health (small orange, 96 grams):

  • Vitamin C – 85% DV
  • Potassium – 174 mg
  • Vitamin A – 4% DV
  • Magnesium – 2% DV
  • Vitamin B6 – 5% DV
  • Sugar – 9 grams
  • Fiber – 2.3 grams
  • Lowers cholesterol
  • Promotes healthy heart

Take note, however, that there are things that you should keep in mind when considering feeding your pets with oranges. Remember that oranges have high sugar content that might cause gastrointestinal upsets when taken in large quantities all at once. The following are some of the side effects and harmful results of too much orange:

  • Not suitable for diabetic dogs as it affects the blood values
  • High acidic value rots teeth faster
  • Causes diarrhea in dogs

Therefore, if you want to give it a try, do so in really small amount and see how they react to it. Note that it is of utmost important that you remove the orange skin (peel it, please!) and remove all the seeds.

ANOTHER IMPORTANT NOTE: Do not give orange juice to your dogs, at all cost! Juices contain way more sugar than there already is in orange fruits.

How Much Orange Can My Dog Eat?

As mentioned in the previous section, even though this fruit is generally safe for dogs, there is a limitation that we must note. It must be taken in little quantities, maybe in one or two segments, taking into account your pet is in perfect shape and health.

Anything more than one to two segments has the potential to cause obesity in your dogs and may then complicate and cause other health issues. In simpler terms, orange combined with other treats should not exceed 10% of your pet’s daily calories. So, if you are someone who loves giving your dogs daily treats, then you must decrease their daily food intake also by 10% to avoid obesity.

This is backed up by Purina Senior Nutritionist Jan Dempsey. She said, “You don’t want to feed your dog anything that will put him off his nutritionally complete meal. Treats can make up about 10% of your dog’s total calories for the day, so for most dogs this means one to three sections.”

Furthermore, once you’ve introduced oranges to your dogs, watch out for any changes in their behavior before making it a part of their regular snacks or treats. Most of the times, no changes usually occur, but you can’t be too sure Plus, better be cautious than be sorry.

If there is any changes in the behavior, then immediately stop feeding them oranges. Also, not every dog has a fascination for citrus fruit, including the tart taste of an orange. While there are dogs that eat anything basically anything you throw at them, you shouldn’t do that.

That said, in addition to limiting the orange intake, do not feed them the peels and the seeds. These can become lodged in your dog’s digestive tract and might cause obstruction that requires surgery. Double check it always.

Again, remove all traces of skin, pith, and seeds as these parts may be dangerous and might even contain toxic compounds from pesticides and other chemicals sprayed on the fruit.

What Should I Do In Case of an Orange Emergency

What Should I Do In Case of an Orange Emergency

While emergency cases involving oranges are rare, it is still best that you know what to do just in case this happens.

First aid for choking depends on whether your dog is conscious or unconscious. If unconscious, slowly and carefully open its mouth and do your best to reach the object with your fingers. Be sure not to push it further. On the other hand, if the dog is conscious, try to apply the modified Heimlich maneuver. That is, turn the pet over to its side, apply pressure just right behind the ribs, and press your hands forward. This simple action could help the dog push the item out.

If you know how to apply first-aid tricks for your dogs, then by all means, do so. However, if you don’t, then don’t even attempt it as it might cause more harm to them. While doing this, make sure that you are on your way to the vet clinic just in case complications arise. Have someone drive you, if possible.

History of Oranges

History of Orange

This fruit is perhaps the most widely favored fruit in the entire world. This citrus was known as Citrus aurantium var. sinensis L. for many, many years and was considered as sour orange (q.v.).

It is still not universally agreed to be a distinct species, C. sinensis Osbeck, but it is usually treated as though it were. One of its first recorded regional names was the Persian narang, from which were derived the Spanish name, naranja, and the Portuguese, laranja. In some Caribbean and Latin American areas, the fruit is called naranja de China, China dulce, or simply China (pronounced cheena).

It is said to have originate in southern China, northeastern India, and perhaps southeastern Asia. It was then introduced to the Mediterranean area by Italian traders after 1450 or by Portuguese navigators around 1500. Before then, this citrus fruits were considered by Europeans to be of great value due to its medicinal purposes. However, it was not the case for oranges. Instead, it became a luscious fruit and only wealthy people had access to it, planting them in private conservatories, called orangeries. By 1646 it had been much publicized and was well known.

Now, it is one of the most commonly grown fruit around the world.

So, if you are thinking of getting oranges for your self-consumption, you might want to take a look at this to help you choose the perfect orange.

The United States Department of Agriculture (USDA) has established the following grades for Florida oranges, which primarily apply to oranges sold as fresh fruit: US Fancy, US No. 1 Bright, US No. 1, US No. 1 Golden, US No. 1 Bronze, US No. 1 Russet, US No. 2 Bright, US No. 2, US No. 2 Russet, and US No. 3. The general characteristics graded are color (both hue and uniformity), firmness, maturity, varietal characteristics, texture, and shape. Fancy, the highest grade, requires the highest grade of color and an absence of blemishes, while the terms Bright, Golden, Bronze, and Russet concern solely discoloration.

Grade numbers are determined by the amount of unsightly blemishes on the skin and firmness of the fruit that do not affect consumer safety. The USDA separates blemishes into three categories:

  1. General blemishes: ammoniation, buckskin, caked melanose, creasing, decay, scab, split navels, sprayburn, undeveloped segments, unhealed segments, and wormy fruit
  2. Injuries to fruit: bruises, green spots, oil spots, rough, wide, or protruding navels, scale, scars, skin breakdown, and thorn scratches
  3. Damage caused by dirt or other foreign material, disease, dryness, or mushy condition, hail, insects, riciness or woodiness, and sunburn.

The USDA uses a separate grading system for oranges used for juice because appearance and texture are irrelevant in this case. There are only two grades: US Grade AA Juice and US Grade A Juice, which are given to the oranges before processing. Juice grades are determined by three factors:

  1. The juiciness of the orange
  2. The amount of solids in the juice (at least 10% solids are required for the AA grade)
  3. The proportion of anhydric citric acid in fruit solids
