Health Benefits of Oregano To Dogs

  1. Supports the Immune System. Oregano is a rich source of antioxidants such as rosmarinic acid and thymol, both of which can help support your dog’s immune system. These antioxidants can help fight against cell damage and inflammation, which can cause several health problems in dogs.
  2. Anti-inflammatory properties. Oregano contains natural anti-inflammatory properties that can help reduce swelling and pain, making it beneficial for dogs that are suffering from arthritis or other inflammatory diseases.
  3. Antibacterial and Antifungal Properties. Oregano has potent antibacterial and antifungal properties that can help fight off infections caused by bacteria and fungus. Research has shown that oregano oil can be an effective treatment for certain types of bacterial infections.
  4. Digestive Health. Oregano also has digestive benefits for dogs. It can help improve digestion by stimulating the release of digestive enzymes and can reduce gas and bloating.
  5. Freshens Breath. Due to its natural antimicrobial properties, oregano can also help freshen a dog’s breath. By eliminating harmful bacteria in the mouth, oregano can help reduce bad breath in dogs.

Potential Risks of Feeding Oregano To Dogs

  1. Intestinal Disturbances. Oregano can cause digestive issues in dogs when consumed in large amounts. The essential oils and other compounds in oregano can irritate the stomach lining and cause vomiting, diarrhea, or other gastrointestinal upset. To avoid digestive disturbances, it’s important to introduce oregano into your pet’s diet gradually and in moderation.
  2. Allergic Reactions. Although rare, dogs can be allergic to oregano, just like humans. Signs of an allergic reaction can include facial swelling, hives, itching or skin irritation, and difficulty breathing. If you notice any symptoms of an allergic reaction, discontinue the use of oregano and seek advice from a veterinarian.
  3. Pregnancy Risks. Oregano should not be given to pregnant dogs as it can cause mild uterine contractions, which can be dangerous to the developing puppies. It is also worth noting that some essential oils, such as thujone, present in oregano can cause miscarriage in pregnant dogs.

Are Dogs Sensitive To Oregano?

While oregano is generally considered safe for dogs, some dogs may be sensitive to this herb. It is important to watch for any signs of sensitivity or allergic reactions when introducing your furry friend to oregano. The following are some of the symptoms you should look out for:

  1. Digestive Upset. Dogs that are sensitive to oregano may experience digestive upset, including vomiting, diarrhea, and loss of appetite. This is because oregano can irritate the gastrointestinal tract in some dogs, leading to discomfort and digestive disturbances.
  2. Skin Irritation or Rash. Dogs with sensitive skin may develop a rash or skin irritation when in contact or when their skin is exposed to oregano, this usually happens when oregano oil comes into direct contact with the skin.
  3. Respiratory Issues. Oregano can also cause respiratory issues in dogs who are sensitive to it. Dogs may experience coughing or sneezing if they inhale oregano powder, which can be dangerous for dogs suffering from respiratory problems such as asthma.
  4. Lethargy and Weakness. In rare cases, dogs may experience lethargy, weakness, or depression when they consume oregano. This is thought to be due to the sedative properties of some of the compounds found in oregano.

If you notice any of these symptoms, you should immediately discontinue the use of oregano and consult with a veterinarian. It is also important to note that oregano is not recommended for pregnant or nursing dogs, as it may cause uterine contractions.

How To Prepare Oregano For Dogs

  1. Add it to their Food. One of the simplest and most common ways to implement oregano in your dog’s diet is to simply sprinkle a small amount on top of their food. Oregano can be added to both wet and dry food and can help add flavor and aroma to your dog’s meal. Start with a small pinch and increase slowly if you notice your dog has no adverse reaction to it.
  2. Make Oregano Tea. Another way to introduce oregano to your pet’s diet is to give them a cup of oregano tea. Simply boil about a cup of water, add a teaspoon of dried organic oregano to it, and let the mixture steep for about 10 minutes. Allow the tea to cool down and give it to your dog in their water bowl or as a treat.
  3. Oregano oil supplements. Oregano oil supplements are a more potent way to implement oregano in your dog’s diet, and they can be added to their food or given as a supplement. Oregano oil supplements are available in most pet stores and online retailers. It’s important to note that oregano oil is highly concentrated and should not be given to dogs in high doses.

How Fast Will Dogs Digest Oregano

For most dogs, oregano breaks down quickly when eaten and passes through their digestive system within 24-48 hours. However, this timeline can vary from dog to dog, depending on the specific factors mentioned above.

The digestive processes in dogs and humans are different. While the food we eat goes to our stomach to be initially broken down, dogs have stronger digestive enzymes that start working in the mouth itself.

However, the digestive time of food ingredients like oregano depends on several factors such as the dog’s age, breed, size, and metabolism.

It’s worth noting that oregano can have a dehydrating effect on dogs if given in large amounts, so it’s important to always provide access to fresh water when adding this herb to your dog’s diet.


Which dogs shouldn’t eat oregano?

Oregano is generally safe for most dogs to eat in moderation, but there are a few cases when dogs should avoid oregano. These include:

  1. Pregnant or Nursing Dogs: Oregano can cause mild uterine contractions, making it a possible risk for pregnant or nursing dogs. It is best to avoid feeding your dog oregano if they are pregnant or nursing to prevent any potential issues.
  2. Dogs with Digestive Issues: Dogs with pre-existing digestive issues such as inflammatory bowel disease (IBD) or gastroenteritis may be more sensitive to the compounds present in oregano. Oregano can irritate the digestive system and cause further complications for dogs that are already struggling with digestion. In such cases, it is best to consult with your veterinarian before introducing oregano to the dog’s diet.
  3. Dogs on Medications: Oregano may interact with some medications, including blood thinners or medications used to treat high blood pressure. If your dog takes medication for any underlying health issues, it is best to consult with your veterinarian before giving them oregano.

Do dogs like the taste of oregano?

Dogs have a very different sense of taste than humans, so it’s difficult to say definitively whether or not they like the taste of oregano. Some dogs may find the flavor and scent of oregano appealing, while others may not be as keen on it.

However, it’s important to note that certain herbs and spices, including oregano, can be toxic to dogs in large amounts, so it’s best to limit their intake and always consult with a veterinarian before introducing any new foods or herbs to your pet’s diet.

In Conclusion

Overall, oregano can be beneficial for dogs when consumed in moderation.

It provides antioxidants and may help treat certain ailments, but it must be used carefully in order to avoid any potential side effects.
