Best natural antibiotics for dogs


Turmeric - a remedy for bacterial infection


For centuries, Asian cultures have harnessed turmeric for its medicinal properties. Its extensive range of health benefits, including anti-inflammatory, antioxidant, and antimicrobial qualities, make it an excellent natural antibiotic for dogs. Today, the widespread availability of turmeric powder in household pantries highlights its growing popularity and ease of use for pet owners.

In essence, turmeric emerges not just as a versatile spice, but as a multifaceted ally in canine health. Its benefits range from treating infections, boosting the immune system, healing wounds to supporting the gastrointestinal system, and promoting liver health. It can also be beneficial for dogs with arthritis, joint pain, or other inflammatory conditions.

Turmeric contains curcumin, a compound known for its anti-inflammatory effects. According to renowned researcher Dr Jane Higdon, curcumin "exerts antioxidant, anti-inflammatory, anticancer, and neuroprotective activities." Research indicates that curcumin's antioxidant effects may play a role in inhibiting the growth and spread of cancer cells.

Turmeric truly earns its moniker as the 'Golden Spice', not just for its vibrant hue, but also for its myriad of benefits, establishing itself as a 'jack-of-all-trades' in the realm of natural remedies. This spice offers a harmonious blend of therapeutic benefits that cater to both preventative and curative aspects of dog health, underscoring its invaluable role in holistic wellness.


Turmeric comes in several forms: powder, paste, or capsules, making it versatile and convenient for different uses. Depending on the form you're using, it can be mixed into a dog’s food, given as a supplement, or applied topically to the affected skin area.

If you're feeling fancy, try making 'golden paste' at home, a beneficial supplement for your dog's diet. This healthful mixture is created by combining turmeric powder, water, and a carrier oil, like coconut or olive oil, enriched with a light sprinkle of freshly ground black pepper. The black pepper is key as it significantly increases the bioavailability of turmeric, ensuring easier absorption.

The general guideline for turmeric dosage is about 15 to 20 mg per pound of body weight per day. Too much turmeric can upset the stomach, causing diarrhea or constipation in certain dogs. It’s best to start with a smaller dose and gradually increase it while monitoring your dog’s reaction.

Oregano oil

Essential oil


When it comes to combatting infections, oregano oil has it all: this potent liquid boasts antibacterial, anti-inflammatory, antioxidant, and antifungal properties. You may think this sounds too good to be true, but its effectiveness is backed by various studies highlighting its principal components - carvacrol and thymol. No worries if chemistry wasn't your forte in school – we've got you covered! Carvacrol and thymol are natural compounds found in various plants, known for their ability to disrupt harmful pathogens, soothe inflammation, and strengthen the body's defenses.

Due to its strong natural antibiotic properties, oregano oil has become a popular choice among dog owners seeking holistic remedies. Its active components can disrupt the bacterial cell membrane, leading to the death of the bacteria. This oil is also rich in antioxidants, which can help neutralize free radicals, reduce oxidative stress in the body, and strengthen the dog's immune system.


There are several effective ways to use oregano oil for treating bacterial and fungal infections in dogs, including skin infections, ear infections, and yeast infections. Oregano oil, when diluted, can be applied topically on affected areas (such as paws and skin), added to your dog's food or water, or even toothpaste for bonus oral health benefits.

Never use pure oregano oil on its own. The recommended dilution for essential oils like oregano oil is 0.5% to 2% depending on the dog’s size, and should be done with a carrier oil. For instance, for each drop of pure oil of oregano, mix with one teaspoon of coconut or olive oil.

Do a spot test on a small area of your dog's skin to check for any adverse reactions before applying on broader areas. Avoid sensitive areas such as the dog's eyes, nose, mouth, and genitals.

Manuka honey

What is the strongest natural antibiotic for dogs?


While the health benefits of honey are widely recognized, the unique properties of manuka honey are lesser known. This special kind of honey provides many extra advantages when compared to regular honey. So what's so special about it?

Sourced from the manuka plant, this caramel-like honey has robust antibacterial properties that have proven effective against all tested bacterial pathogens. Manuka honey’s antiseptic, antifungal, and anti-inflammatory properties make it incredibly beneficial for treating wounds, burns, and ulcers.

Better yet, its capability of neutralizing drug-resistant agents makes this golden liquid a powerful natural antibiotic for dogs with antibiotic resistance. Thus many pet owners opt for manuka honey over regular honey, despite the premium price.


Manuka honey can be used topically to promote healing and prevent infections in dogs’ skin. When taken orally, it can help combat respiratory infections like kennel cough. Its antibacterial properties work to prevent infection, support faster healing, and significantly reduce inflammation in both applications.

Due to its high sugar content, manuka honey should not be given to dogs in large quantities or to dogs with certain health conditions such as diabetes.

Using natural antibiotics safely and effectively

Healthy dog

You may wonder, “Aren’t natural antibiotics for dogs safe?” Indeed, when used correctly, they pose no harm to your pet. However, just like any treatment, they should be carefully administered, and in some cases, professional guidance is needed.

Possible side effects

Although natural antibiotics are generally safe, monitoring your dog for any potential side effects is essential. This includes observing positive signs in your dog such as improved energy, shinier fur, better appetite, and overall well-being, which may indicate a good response to natural antibiotics. However, be aware that some dogs may experience adverse reactions.

For instance, while manuka honey can provide health benefits, it should be used in moderation, especially for overweight or diabetic dogs.

Turmeric is often combined with black pepper to aid in absorption. However, too much pepper can be irritating for dogs. Additionally, consult with a vet if your dog has health issues related to the liver, kidneys, or gallbladder before giving them turmeric.

Consulting with your veterinarian

The importance of consulting with your veterinarian before administering natural antibiotics to your dog cannot be overstated. Your vet can provide valuable insights on the appropriate dosage, potential side effects, and any specific considerations or interactions with your dog’s other medications. This proactive approach will help you make informed decisions for your dog’s health.

Additional natural remedies for dogs

Dog yogurt

In addition to the 3 natural antibiotics we’ve explored, other natural cures can significantly improve your dog’s overall well-being. Each of these remedies offers unique benefits and can be utilized as preventive measures to support your dog’s health.


Natural probiotics, such as yogurt or kefir, can help maintain a healthy balance of gut bacteria in dogs, supporting digestion and overall health. These beneficial bacteria can:

  • Help in establishing healthy gut flora

  • Promote immunity against bacterial or fungal infections

  • Prevent allergies

  • Aid in digestion

  • Alleviate gastrointestinal issues such as diarrhea.

Apple cider vinegar

Apple cider vinegar is a versatile natural remedy that can help with skin infections, gut inflammation, and wound healing in dogs.

The antibacterial properties of apple cider vinegar protect against harmful bacteria, making it highly beneficial for dogs. However, proper usage and veterinary consultation are necessary to prevent potential irritation.

Coconut oil

Coconut oil is another natural remedy with antifungal and antibacterial properties. It’s beneficial for improving skin conditions, and digestive problems, and treating wounds and infections in dogs.

Coconut oil can be introduced gradually to their diet, which can help prevent any potential gastrointestinal upset. It can also be used to dilute pure oil of oregano for proper dosage.

How to choose between natural and conventional antibiotics

Various natural antibiotics for dogs

Although natural antibiotics offer numerous benefits for dogs, conventional antibiotics may be a more suitable choice in certain instances. Understanding when to use each type of antibiotic can be critical in ensuring your dog receives the best treatment possible.

Natural antibiotics are an excellent choice to treat infections, especially for mild cases, and can be used as a preventive measure. They may be applied to address minor wounds and bacterial infections in dogs.

On the other hand, conventional antibiotics are recommended for severe infections or cases where natural remedies have not been effective. Some examples of severe infections in dogs that respond well to conventional antibiotics include antibiotic-resistant bacterial infections, urinary tract infections, eye infections, and respiratory infections.


In conclusion, natural antibiotics offer a great alternative for treating bacterial infections in dogs, particularly for less severe conditions. Top contenders for the strongest natural antibiotics for dogs include turmeric, oregano oil, manuka honey, and turmeric. Additionally, other natural remedies like probiotics, apple cider vinegar, and coconut oil can significantly improve your dog’s overall health and well-being. While natural antibiotics are generally safe, it’s important to use them responsibly and under the guidance of a professional.
