After the first day if the vomiting and stooling stops, then you can gradually introduce a bland diet of just boiled white rice and plain boiled boneless chicken breast, boiled white fish or scrambled egg; no seasoning and no oils. 

[5] In what ways can olive oil be good for your dog?

Olive oil is beneficial to both humans and dogs, and when added to your dog’s diet it can work wonders for your dog’s beauty and overall health. Here are some of the amazing benefits of olive oil for dogs.

[6] Cooked vs raw olive oil. Which is better for my dog?

We all know that fats and oil become damaged when they are exposed to heat but the effect of heat on different oils vary. Most oils will oxidize and hydrogenate to some degree when heated repeatedly. 

Oils with a high amount of polyunsaturated fats, such as soybean oil and canola oil, are very sensitive to heat while oils rich in saturated fats, like coconut oil, are very resistant to heat. For olive oil, it’s particularly rich in monounsaturated fats which makes it resistant to oxidation and hydrogenation, and gives it the ability to withstand heat. 

Monounsaturated and saturated fats make up 87% of the olive oil with only 11% polyunsaturated fats. Therefore, olive oil is highly heat-resistant and doesn’t undergo much damage when cooked or heated. Uncooked olive may not be exactly the same with cooked olive oil, but they are not much different, and cooked olive oil retains all its healthy fats and anti-inflammatory compounds.

The best way to regulate the amount of olive oil your dog consumes is by ensuring that they get it only from their diet. If you feed your dog some commercial food brand, find out if it contains olive oil and the exact amount it contains by verifying the ingredients in the dog food. 

If your dog’s food contains enough then you may have no need to introduce more to their meals. If you’re not sure about what decision to make, you can talk to your vet about your concerns. 

Besides the actual meals, verify the contains of any treats, supplements and medications for your dog to avoid a painful episode of gastrointestinal inflammation due  to ingesting too many oils at once. 

Also ensure that you keep olive oil bottles and all forms of oils out of your dog’s reach to prevent them from accessing it in your absence. 

[8] Are there any safer alternatives to olive oil for my dog?

Generally, oils should be given to dogs in moderation because too much of it will certainly have negative consequences, including stomach upset in the short term and excessive weight gain in the long. Besides olive oil, here are some other excellent oils for dogs. 

Sunflower oil: sunflower oil contains omega-6 fatty acids which supplies your dog with healthy fats, it improves heart health, boosts immune system and increases energy level, and it’s also great for dogs with sensitive stomachs.

Coconut oil: just like olive oil, coconut oil is healthy for dogs and contains a healthy version of saturated fats. Extra virgin coconut oil helps dogs maintain a healthy weight, improves dry skin and improves energy levels. It also helps with bad breath in dogs. 

Flaxseed oil: this oil is rich in alpha-linolenic omega-3 fatty acid which is excellent for heart health. It also helps promote the normal function of the kidney, regulates blood pressure and improves mobility in arthritic dogs.

[9] Olive oil overdose. At what point should I phone my vet?

If you observe that your dog is in serious discomfort after a meal containing olive oil, or they accidentally got into a bottle and helped themselves to a generous amount of olive oil, then it may be a painful episode of gastritis or pancreatitis with bouts of diarrhea and vomiting. 

You may not need to call a vet immediately, first try to eliminate every form of food and let your dog fast from food for 24-48 hours while giving them small quantities of water frequently to keep them hydrated. Call your vet if your dog is unable to drink small water without vomiting or if symptoms persists after 24 hours of fasting from food. 

[10] How might a vet treat my dog?

A vet will administer a gut-safe anti-vomiting injection to your dog to help stop the vomiting. Your dog may also be given a pet-safe antacid to help soothe their nausea and if the dog is dehydrated then fluid therapy will help replenish the lost body fluids. If the inflammation has developed into severe stomach ulcer then your dog will need a proton pump inhibitor to inhibit the secretion of stomach acids.

Closing Thoughts

Olive oil may have great health benefits for dogs but when consumed in large quantities it can lead to digestive distress in dogs with sensitive stomachs and cause symptoms like diarrhea and vomiting. 

A dog suffering from gastritis or pancreatitis should be made to fast from food for at least 24-48 hours and should also be closely monitored and taken to a vet if symptoms don’t relent after 24 hours or water intake triggers vomiting. 

Extra-virgin olive oil consumption in dogs should be very moderate and with caution as consistent use may also lead to weight gain.
