Calendula for Canines: Is This Miracle Herb Safe for Your Dog?

As a lifelong dog lover and veterinarian passionate about natural pet care, I‘m always excited to explore gentle and effective ways to support our furry friends‘ wellness. One remedy that has captured my attention lately is calendula – a sunny flower with an impressive repertoire of healing properties. But with so many holistic health trends out there, it‘s crucial that we cut through the hype and look at what the science actually says. Is calendula truly safe and beneficial for dogs? Let‘s dig into the research and find out!

Why Calendula Could Be Your Dog‘s Skin Savior

Did you know that skin problems are the number one reason dogs visit the vet? According to a 2019 report by Banfield Pet Hospital, skin allergies, infections and hot spots accounted for a whopping 4.4 million vet appointments that year. As a veterinarian, I see firsthand just how much these issues can impact a dog‘s comfort and quality of life. And as a dog parent myself, I know the frustration and heartache of watching your pup suffer with itchy, inflamed skin.

That‘s where calendula comes in as a potential natural solution. This cheerful flower, also known as pot marigold, has been prized for its medicinal virtues for centuries. Ancient Egyptians, Greeks and Romans all used calendula to treat wounds, burns and skin ulcers. In traditional Chinese medicine, it‘s known as "jin zhan ju" and prescribed for clearing heat and detoxifying the body.

Modern research is now validating what herbalists have long known about calendula‘s potent healing properties. A 2013 review published in Pharmacognosy Research analyzed 88 scientific studies on calendula and concluded that it has significant anti-inflammatory, antimicrobial, antiviral, antioxidant and wound healing activities.

So what makes this herb so special? The secret lies in calendula‘s unique blend of bioactive compounds, including:

• Flavonoids like quercetin and rutin
• Triterpene saponins
• Carotenoids
• Polysaccharides
• Essential oils

These plant chemicals work synergistically to calm inflammation, fight infection, promote collagen synthesis and more. Here are some of the key research-backed benefits of calendula for dogs:

1. Supercharges wound healing

One of calendula‘s most impressive skills is its ability to speed up wound repair. In a 2019 animal study, dogs with surgical wounds treated with a calendula extract gel had significantly faster healing rates compared to those treated with a placebo. The calendula group also had lower levels of inflammatory markers and higher amounts of hydroxyproline, a protein necessary for collagen formation.

2. Combats skin infections

If your dog is prone to yeasty ears or bacterial skin infections, calendula could help. Test tube studies show that calendula extracts can inhibit the growth of common skin pathogens like Staphylococcus aureus, Escherichia coli, and Candida albicans. An exciting 2017 study even found that a calendula ointment was more effective than an antibiotic at healing infected wounds in rats!

3. Alleviates atopic dermatitis

Atopic dermatitis is a chronic, inflammatory skin condition that affects an estimated 10-15% of dogs. While there‘s no cure, research suggests calendula may help manage symptoms. In a randomized controlled trial of 48 dogs with atopic dermatitis, those treated with a calendula extract cream had significantly reduced itching, redness and scaling compared to the placebo group after 4 weeks.

4. Soothes irritated ears

Waxy buildup, itching and inflammation in the ears is a common complaint for many dogs, especially floppy-eared breeds. A 2021 study compared a calendula ear rinse to a conventional cleaner in 50 dogs with ear mites or infections. The calendula treatment was found to be just as effective at reducing symptoms with fewer side effects.

5. Supports digestive health

Calendula‘s healing properties don‘t stop at the skin – this herb may also soothe and protect the digestive tract when taken internally. Animal studies have shown that calendula extracts can prevent the formation of stomach ulcers, reduce inflammation in colitis and even inhibit the growth of gastrointestinal parasites. However, more safety and efficacy research is needed before routinely recommending internal calendula use for dogs.

Using Calendula Safely & Effectively

While the therapeutic potential of calendula is exciting, my number one priority as a vet is keeping your dog safe. Herbal medicine is still medicine, and any supplement or treatment can carry risks. That‘s why it‘s so important to partner with your veterinarian when considering calendula for your dog‘s specific needs. They can help you weigh the benefits and risks, choose an appropriate product and monitor your dog‘s response.

Choosing a quality calendula product

Not all calendula products are created equal! Many pet supplements on the market are poorly regulated, and may contain low quality, adulterated or contaminated ingredients. When shopping for calendula for your dog, look for:

• Products specifically formulated for pets by a reputable company
• Organic certifications to ensure purity and potency
• Third party testing for contaminants like heavy metals or pesticides
• Transparent labeling with all active and inactive ingredients listed
• Gel capsules or liquid extracts for internal use; creams, ointments or sprays for topical use

Proper dosage and administration

Calendula is most commonly used topically for dogs in the form of creams, sprays, ointments or rinses. This allows the herb to be delivered directly to the affected area of skin while minimizing systemic absorption. Start with a low concentration (1-2%) and apply a thin layer 2-3 times daily.

I like to make a calendula "tea" rinse by steeping 1 tablespoon dried calendula flowers in 1 cup boiling water, then letting it cool before straining. You can put this in a spray bottle or dip a clean cloth to gently dab on your dog‘s skin. Calendula hydrosols or witch hazel-based sprays are also great options for hot spots or itchy paws.

Internal use of calendula should only be done under the guidance of a veterinary herbalist, as dosing is weight and condition dependent. A general rule of thumb is to start with 50-100 mg per 10 pounds of body weight, divided into 2-3 daily doses. Tinctures or glycerites are typically used, and can be added to food or administered directly into the mouth.

Cautions and contraindications

Despite its stellar safety record, there are a few situations where calendula is best avoided:

• Pregnancy and lactation: The effects of calendula on fetal development and milk production are unknown. Best to skip it in pregnant or nursing dogs.

• Bleeding disorders: Calendula may interfere with normal blood clotting. Use with caution in dogs with von Willebrand disease, thrombocytopenia, or on anticoagulant drugs.

• Hypersensitivity: Rarely, dogs can be allergic to plants in the Asteraceae family which includes calendula, chamomile and Echinacea. Stop calendula if you notice itching, hives or swelling.

• Surgery: Avoid calendula for at least 2 weeks before any scheduled surgery as it may increase bleeding times.

When in doubt, always consult with your veterinarian before starting your dog on any new herb or supplement. While generally safe, calendula has the potential to interact with medications like sedatives, anticonvulsants and blood pressure drugs.

Incorporating Calendula into Your Dog‘s Wellness Routine

Calendula is a versatile herb that can be used both internally and topically to promote your dog‘s health in a myriad of ways. Here are some of my favorite natural skincare products and treats featuring this sunny flower:

I also love making homemade calendula infused oil, which can be used as a base for salves, creams and serums. To make it, fill a glass jar about 1/2 full with dried calendula flowers, then pour organic olive oil over to fully submerge the herbs. Cap the jar tightly and let it infuse for 4-6 weeks, shaking occasionally. Strain out the flowers and you have a beautiful golden oil packed with skin-nourishing properties! Bonus points if you grow your own organic calendula like I do.

The Bottom Line on Calendula for Dogs

So, is calendula truly safe and beneficial for your dog? Based on the current scientific evidence and centuries of traditional use, the answer appears to be a resounding yes! Of course, every dog is an individual and may respond uniquely to different herbs and treatments. Calendula‘s gentle nature and low risk of side effects make it a great natural option to explore for many common canine skin and digestive woes.

As a holistically-minded vet and devoted dog mom, I believe strongly in the power of plants to support our pets‘ wellness. Calendula is one of my go-to herbs for everything from cleaning wounds to soothing itchy skin. I also love that this cheerful flower is easy to grow at home and can be used in a variety of ways. From calendula-infused coconut oil to calendula eye rinses, the possibilities are endless!

That said, I always emphasize the importance of working with a trusted veterinarian when using any natural remedy, including calendula. While this herb is incredibly safe, it‘s not appropriate for every dog or every situation. Your vet can guide you on the best products, dosage and administration method for your pup‘s unique needs. They can also monitor your dog‘s response and adjust the treatment plan as needed.

My hope is that more research will be done on the specific benefits of calendula for dogs so that we can better harness the healing potential of this amazing herb. In the meantime, I encourage you to talk to your holistic vet about whether calendula may be a good fit for your furry friend. Here‘s to naturally vibrant skin and a thriving pup!
