Apple Cider Vinegar For Dogs 2025: Benefits, Risks & How To Use

For centuries, traditional medicine has celebrated the many benefits of apple cider vinegar (ACV). Its remarkable uses span from human health, environmental hygiene, and our animal companions’ well-being.
These days, many dog owners and pet parents are rediscovering the wonders of apple cider vinegar. This simple product, derived from fermented apple juice, has proven health benefits when used internally and externally for dogs. ACV is popular among those seeking natural remedies for their pets’ health concerns, from enhancing gut health to soothing itchy skin.
Keep reading to find out more about apple cider vinegar for healthy dogs. We’ll explore potential side effects and guide safe and effective usage. Our exploration is grounded in scientific evidence, ensuring your furry friend can avoid the side effects of apple cider vinegar while safely enjoying the many benefits.
Can I Safely Give My Dog Apple Cider Vinegar?
You can safely give your dog apple cider vinegar to assist with preventing a range of health concerns. It can aid digestion, improve skin and coat health, serve as a flea repellent, and even boost oral health. However, it’s essential to use it safely. Use it only diluted, and always consult with a veterinarian before introducing it to your dog’s regimen due to possible side effects.
Apple Cider Vinegar Health Benefits For Dogs

Gut Health
The acetic acid in apple cider vinegar promotes good digestion and encourages the growth of beneficial bacteria in a dog’s gut. It’s believed that ACV gives your dog’s body an extra line of defense against common ailments such as urinary tract infections and kidney disease.
Skin And Coat Health
Applying a diluted apple cider vinegar mixture can dramatically improve a dog’s skin and coat health. It provides soothing relief for irritated skin, dry skin, and hot spots while also helping to manage yeast infections. Adding ACV to dog shampoo can enhance these benefits and make your dog’s coat soft and shiny.
Flea Repellent
Apple cider vinegar can double as a natural flea repellent. Fleas dislike the acidity of ACV, making it a great choice for dog owners who prefer to avoid chemical treatments. Regularly spray your dog’s coat with a diluted apple cider vinegar mixture to deter fleas to spare your dog from allergic reactions.
Dental Health
Good oral health is vital for dogs, and apple cider vinegar can lend a helping paw in this area. It’s believed to help prevent tooth decay and regulate the oral pH level, keeping your dog’s teeth strong and healthy.
Ear Health

Apple cider vinegar can also aid in preventing itchy ears and ear infections in dogs. Apply diluted apple cider vinegar to your dog’s ears with a cotton ball. It will promote a healthy ear canal and deter the growth of the yeast and bacteria[1] that can cause ear infections.
Joint Health
The natural anti-inflammatory properties of apple cider vinegar may help to alleviate joint pain and inflammation in dogs, particularly for senior dogs and those suffering from arthritis or hip dysplasia.
Immune Support
The high concentration of vitamin B found in apple cider vinegar can boost your dog’s immune system, helping them stay healthy and fight off potential infections.
Weight Management

Preliminary research[2] on other mammals suggests that apple cider vinegar might reduce the risk of obesity. By promoting a feeling of fullness and reducing oxidative stress[3], ACV helps overweight dogs shed some pounds.
Blood Sugar Regulation
Apple cider vinegar has been studied for its potential to regulate blood sugar levels[4], which could benefit dogs with diabetes.
Allergy Relief
For dogs with allergies, apple cider vinegar can relieve symptoms such as itchy skin and runny eyes, making it a valuable addition to any allergy management plan.
Apple Cider Vinegar Side Effects On Dogs
While apple cider vinegar can offer many potential health benefits for dogs, it’s important to be aware of the potential side effects. Undiluted apple cider vinegar, or excessive amounts even when diluted, can potentially cause harm, such as:
- Digestive Issues. If your dog ingests large amounts of apple cider vinegar, it may irritate the digestive tract. Symptoms can include vomiting, diarrhea, or discomfort. They may be severe in some cases- one reason why it’s crucial to always properly dilute apple cider vinegar before giving it to dogs.
- Skin Irritation. Just like undiluted apple cider vinegar can irritate a dog’s stomach, it can also cause skin irritation. Therefore, always dilute it before applying it to your dog’s skin or fur.
- Tooth Enamel Erosion. While apple cider vinegar can promote oral health, it’s also acidic, which means it can potentially erode tooth enamel over time. So again, this underlines the importance of dilution.
- Potential Drug Interactions. If your dog is currently taking medication, it’s essential to check with your vet before introducing apple cider vinegar. It could interact with some drugs.
Always consult a veterinarian before introducing apple cider vinegar to your dog’s diet or health regimen. Remember that while apple cider vinegar can provide numerous benefits, it’s not a substitute for professional veterinary care.
How To Give Your Dog Apple Cider Vinegar?
If you’re considering adding apple cider vinegar to your dog’s health routine, there are several ways to do it. It can be mixed in small doses into your dog’s food or water[5] or even applied externally for skin conditions.
Apple Cider Vinegar In Dogs’ Water Benefits
To add apple cider vinegar to your dog’s water, begin with small amounts and monitor your dog’s reaction. Apple cider vinegar in dogs’ water can include improved digestion and a shinier coat. You can also mix it into their food, but be careful not to overdo it, as the strong taste may discourage them from eating.
Apple Cider Vinegar On Dogs’ Skin Benefits
For topical application, particularly to address skin conditions, create an apple cider vinegar mixture using one part vinegar to one part water in a spray bottle. You can apply this mixture to your dog’s fur or skin, making sure to avoid eyes and any open wounds as it can cause irritation. Always remember to test the solution on a small area first to ensure your dog doesn’t have an allergic reaction.
How Much ACV Should You Give To Your Dog?
When it comes to determining the proper dosage of apple cider vinegar, size matters. A general guideline is to add 1 teaspoon of diluted apple cider vinegar to your dog’s water or food for every 15 pounds of body weight.
However, small dogs, older dogs, and dogs with certain health conditions may require different dosages. Small dogs should start with less ACV, as they might be more sensitive when they consume apple cider vinegar internally. Elder dogs or dogs with health issues such as kidney stones or skin infections may also need special dosage considerations.
Regardless of your dog’s size or health condition, it’s crucial to consult with your veterinarian before introducing any new supplement. Your vet can help determine the most safe and effective dosage for your dog’s specific needs. They can also help you monitor your dog’s health and adjust the regime as necessary.
Conclusion
Apple cider vinegar, a product of the fermentation process of apple juice, is proving itself as a versatile health supplement not just for humans but for our canine companions too. It promotes gut health, enhances skin and coat condition, serves as a natural flea repellent, and even aids in oral health, among other benefits.
However, it’s important to remember that it’s not a cure-all. While many pet parents attest to its effectiveness, not all dogs may react the same way. Before buying apple cider vinegar and introducing it into your pet care routine, consult your veterinarian to ensure it is safe and beneficial for your pet. The many health benefits of apple cider vinegar are promising, but you must use it safely and responsibly.
