Facts About Olives

Olives (scientific name Olea Europaea) are an oval-shaped fruit known for their delicious taste and high nutrient content.

Olives contain high levels of vitamins, minerals, antioxidants and good fats, which provide numerous health benefits to humans.

This amazing fruit can help lower cholesterol and blood pressure levels as well as prevent heart disease and certain cancers.

Olives also improve digestion, reduce inflammation, soothe allergic reactions and defend against infections.

The olive fruit was originally native to Asian Minor before spreading to the Mediterranean region around 6000 years ago and is considered one of the oldest cultivated trees in the world today.

Olive trees can live up to 1,500 years. The oldest tree is on the island of Crete and believed to be more than 3,000 years old.

Spain is the most significant producer of olives, followed closely by Italy, Greece and Turkey.

Olives are an essential ingredient in the Mediterranean diet, often used in dishes such as salads, pizzas and tapenade.

There are nearly 2,000 different varieties of olives grown around the world, but the main ones are green olives and black olives.

But what is the difference between green and black olives?

Green olives are picked from the tree before they are ripe whereas black olives are left to ripen on the tree.

However, olives are a fruit that you cannot eat raw because they have an extremely bitter taste, requiring a curing process to make them edible.

But can we share olives with our dogs or are olives poisonous to dogs?

Can Dogs Eat Olives?

Dogs can eat olives. They are not toxic for canines, but you must exercise caution before feeding any to your dog.

The best type of olives to feed your dog are plain, unsalted and always given in moderation. Organic olives obviously cost more but are the best choice when considering your dog’s health.

You must first completely remove the pit to avoid damaging your dog’s teeth. If the dog chews on it, it can cause choking or digestive issues.

Always start by giving your dog just a tiny piece of olive and observing him for any adverse reactions such as a dog allergy.

Are Olives Bad for Dogs?

When dogs eat olives, if they consume too many or ingest the pit, they could quickly experience digestive issues such as an upset stomach, stomach pain or diarrhea.

If your dog does accidentally eat a significant amount of olives, consult your veterinarian immediately.

You should avoid canned or pickled olives due to the high levels of sodium these contain, which studies reveal are extremely bad for dogs.

Too much salt easily dehydrates a dog, and consuming high amounts of sodium over an extended period can eventually lead to high blood pressure.

In addition to sodium, many products also contain seasonings and additives that are harmful to dogs.

Always check the ingredients before giving any stuffed olives to your dog to look for foods unsuitable for canines, such as anchovies, blue cheese or feta cheese.

It is also highly likely that stuffed olives include preservatives and other ingredients such as garlic, which is known for being extremely toxic to dogs.

Although most dogs can eat bread, you should avoid giving olive bread to your pup for the same reason.

If your dog does eat any food containing garlic, he may show signs such as lethargy or have difficulty breathing. Have your dog examined by a vet straight away for treatment should this occur.

Also, resist the temptation to give your dog olives from your pizza topping or those used in a cocktail drink because both could be harmful to your pooch.
