We rescued a very sick 9 week old male pom. He was very weak and had kennel cough, with signs of pneumonia, and underfed...We decided to just give KC-Defense a try. Within just two days we saw immediate results. Now at 3 weeks, all symptoms cleared up. THANK YOU!! - Patricia, TX, USA

What is KC-Defense?

KC-Defense is a safe, non-addictive, 100% natural homeopathic OTC medicine formulated especially for pets to relieve and soothe kennel cough and other respiratory tract infections. It may be used before visits to the vet, kennels, catteries, etc. or acutely to address an active infection.

KC-Defense is also an excellent companion remedy to homeopathic Respo-K™, as it relieves the symptoms of colds and respiratory infections in pets. Used together, KC-Defense and Respo-K can provide immediate symptomatic relief of respiratory infections and kennel cough in pets, and improve long-term respiratory health by strengthening the immune system and promoting optimal lung functioning.

KC-Defense comes in convenient, dissolvable granule form. Safe and easy to administer, these pleasant tasting granules are simply sprinkled on your pet's tongue and rapidly absorbed in the mouth.

All PetAlive homeopathic products and biochemic tissue salts are manufactured in a FDA and GMP registered pharmaceutical facility under the supervision of qualified homeopaths and responsible pharmacists. Individual ingredients are listed in the Homeopathic Pharmacopoeia of the United States (HPUS).

What is kennel cough and what are the symptoms?

Kennel cough is a highly contagious upper respiratory infection that often affects animals that are kept in a confined space such as boarding kennels, dog shows or veterinary hospitals.

Symptoms include a persistent dry hacking cough or bouts of deep harsh coughing often followed by gagging, which may produce a foamy mucus.

What is the conventional treatment?

Mild cases may improve without treatment. Conventional treatment of kennel cough often involves antibiotics which tend to relieve the animal's symptoms fairly quickly, but also have a general weakening effect on their immune system, which can cause further problems, especially in the long-term.

Vaccinations to prevent kennel cough are also often recommended. But research indicates that frequent vaccination or over-vaccination may unnecessarily stress a pet's immune system.

The natural way

Respiratory health in pets involves taking a holistic approach in order to address kennel cough, as well as the health of the nose, throat and chest.

In fact, any place where animals tend to congregate – even when going for a walk in the park – can pose a risk. For this reason, maintaining peak health in the respiratory and immune systems is very important in the quest to keep your pet healthy.

In the wild, animals instinctively seek out plants that will help to support health in various body systems. It therefore makes sense that as owners, we can help our domestic pets by making herbal and other natural supplements available to them.

As part of a holistic approach to pet health, natural remedies can help to build and strengthen your pet's immune system, encourage the elimination of toxins and generally improve the overall health of your animal.

Natural remedies can also help to relieve specific symptoms such as upper respiratory infections and coughs without the accompanying toxin build-up caused by conventional treatments.

What are the Ingredients?

KC-Defense is a 100% homeopathic formula and contains the following ingredients in therapeutic dosage: Bryonia (6C), Echinacea purp (3X), Ferrum phos (6C), Kali sulph (6C), Mag phos (6C), Plantago (3X), Sucrose.

  • Plantago (3X) is a homeopathic remedy that is well known for treating dry coughs. It is also an effective expectorant and anti-catarrhal and helps to expel mucus build up in the lungs. Plantago is also approved by the German Commission E for internal use to soothe throats and the mucous membrane irritation associated with upper respiratory tract infections. Clinical studies have supported its effectiveness in the treatment of bronchitis (Wegener T, Kraft K. “Plantain (Plantago lanceolata L.): anti-inflammatory action in upper respiratory tract infections”. Wien Med Wochenschr 1999;149(8-10):211-216.).
  • Bryonia (6C) is a proven natural remedy which is very effective for the treatment of coughs and dry mucus membranes, as well as the clearing of mucus from the chest.
  • Echinacea purp (3X) is one of the top selling ingredients for the treatment of colds, flu and other viral infections. Clinical trials have proved its effectiveness in supporting the immune system (Schoneberger D. “The influence of immune-stimulating effects of pressed juice from Echinacea purpurea on the course and severity of colds”. Results of double-blind study. Forum Immunol 1992;8:2-12.) (Taylor JA, Weber W, Standish L, et al. “Efficacy and safety of echinacea in treating upper respiratory tract infections in children: a randomized controlled trial”. JAMA 12-3-2003;290(21):2824-2830). Studies have shown that Echinacea works by preventing the formation of hyaluronidase - an enzyme that is known to break the cell barriers between healthy tissue and pathogenic organisms like viruses. This immune boosting herb has also been successfully used to restore immune functioning in patients who have undergone chemotherapy and during recovery and convalescence from major illness.
  • Ferrum phos (6C) is one of the most important biochemic tissue salts to use when there is any infection or inflammation in the body. It helps to distribute iron and oxygen throughout the body, strengthen cell walls and fight infection.
  • Kali sulph (6C) is a biochemic tissue salt that is essential for distributing life, giving oxygen throughout the body and keeping cell membranes in peak health. It is often called the 'natural antibiotic' of the tissue salts and together with Ferrum phos can treat both the initial, secondary and third stages of infection. Kali sulph is used for a variety of chest infections, including chronic cough, asthma, bronchitis and even pneumonia.
  • Mag phos (6C) is a natural painkiller and antispasmodic and is very helpful for bronchial spasms and other forms of spasmodic cough.
  • Sucrose (inactive ingredient)

Note: Safe for animals of all ages, pregnant animals or animals that are nursing. KC-Defense can safely be used along with prescription medications.

Get optimum results with regular use

While conventional medicine works by often treating just the symptoms, natural medicine strives to create holistic balance. Unlike pharmaceutical drugs, the natural ingredients in our remedies support overall health and functioning.

Pets respond to natural medicine in different ways. Some of our satisfied customers have reported observing immediate results in their pets while many others have reported observing optimal benefits taking effect within 3-6 weeks. To ensure your pet receives optimum results it is important to administer natural remedies as directed and remain consistent. You may also find that giving your pet a smaller maintenance dose is beneficial for ongoing support.

How long until we see results?

Because KC-Defense is 100% homeopathic, it supports the animal body on a cellular level – getting to work upon the first dose. Response times may vary from pet to pet, but should be noticed within 24-48 hours on average. For long-term support of the respiratory system, Respo-K is recommended.

How long will a bottle last?

One bottle of KC-Defense will last for 15-30 days, depending on the size and needs of your pet.

    When I first researched this product and purchased it I must admit I was skeptical. I have a 8 month Akita (Bruno) who is very socially active, with scheduled play dates, dog park, training, puppy play care, etc. With the holidays he contacted kennel cough, we put him on antibiotics and I also ordered KC-Defense. Shortly after his kennel cough was completely gone, I had to leave my husband and Bruno for two weeks. My husband used the first bottle of KC-Defense not realizing we had more and stopped giving him KC-Defense while I was away. When I returned Bruno had a slight hacking cough. I immediately started him back on the KC-Defense and within a week the cough was completely gone. As long as Bruno is socially active with other animals, I will continue to use this product and highly recommend it to others.

How has KC-Defense helped others?

KC-Defense has been used to help many kennel cough sufferers. Here’s what some pet owners have to say:

"KC-Defense helped our puppy recover from kennel cough which went on and on with such terrible coughing! Thank you for a great product!"


“After successfully treating my Afghan with KC-Defense, I will not send her to the kennels without it! At least I can be confident that she is protected as her system is very sensitive and she easily picks up infections from other dogs. This product is great! Once again I have been very impressed by your service and your products!”


“We rescued a very sick 9 week old male pom. He was very weak and had kennel cough, with signs of pneumonia, and underfed. After literally weeks of treatment with antibiotics and other strong meds, Cujo was still racked with a bad cough and phlegm discharge. The vet was ready to send him to A&M for help. We decided to just give KC-Defense a try. Within just two days we saw immediate results. Now at 3 weeks, all symptoms cleared up. THANK YOU!! He is now a robust little guy that is so much fun.”

—Patricia, TX, USA

KC-Defense is incredible! When we adopted a puppy from the pound, we didn't know she had kennel cough, or that she would pass it to our 7 year old dashed mix. I gave them both hourly doses of KC-Defense, and by the 3rd dose the terrible, hacking cough had disappeared! By the end of day one, they both looked happier, and no more sneezing! I will definitely recommend this to my friends.”

—Becky M., CA, USA

“Just a note to thank you for your products I received. My dog is very ill with kennel cough and after just 6 doses is remarkably better. It's amazing. I was so worried about him and a little skeptical of the claims of KC-Defense, but I was proven very wrong and happily so. I am going to order human supplements now and am recommending you to my brother-in-law who is a psychologist. Thank you and I am sure if my dog could thank you, he would!!!!”

—Anne M.

“My lab puppy contracted kennel cough on a trip to a new vet. About 3 days later he started coughing. I took him to my normal vet and he didn't want to treat it right away because sometimes it clears up by itself. However, it didn't, and we went through 2 sets of antibiotics and also cough tabs. To no avail, he was getting worse and now had been coughing for 3 months! I decided to check to see if there was a natural way to get rid of this annoying cough for him and for our family, as the puppy wasn't sleeping and neither were we. I came across this website and read about the KC-Defense. I ordered it and started it on a weekend. On the second day, he had NO cough and was resting well at night as were we. I NEVER would have believed that this would work. Well it has, and we are totally thankful!! This is amazing stuff!! I highly recommend it!”

—Becky, NY, USA

“Just wanted to let you know how well this worked and how quickly I saw results with KC-Defense for kennel cough. I had a litter of Labradoodles who began a dry, hacking cough this winter when due to cold weather, our kennel had little air circulation. I purchased the 3-pack to receive a discount and only used 1 bottle for a litter of 8 pups. I administered it individually as well as added a bit to their drinking water to ensure each puppy received a sufficient amount. Thanks a bunch, I will keep this on-hand!”

—Belle, OH, USA

“I have a lil toy poodle that had Kennel cough for 3 months and on 6 different antibiotics. I'm so grateful I found KC-Defense after just using the product for 3 wks the cough was gone thank you.”

—Lynda, PA, USA

“We had never experienced [this] before, but the next to the youngest of our five dogs suddenly came down with a terrible hacking …cough. Even though we took the …puppy to the vet and was given medicine for him, the hacking cough just would not go away. I ordered the KC-Defense, began giving it to the …puppy right away, and also to the other dogs as a preventative in hopes they would not get the [cough]. The puppy’s coughing subsided within just a day or two. We had one other dog that showed signs of contracting the [cough], but soon after we gave her the KC-Defense, her cough went away. All the dogs are now happy and healthy again!!! Thank you!!!”

—Brenda, VA, USA

“I cannot say enough about this product. I just adopted a dog that was quite sick. She had to be in the hospital for 16 days. She had [upper respiratory issues] that caused her to cough continuously. She was put on [medication] and even then she couldn't stop coughing. It appeared she would have to live with this cough UNTIL I tried KC-Defense. It worked immediately! I started out giving it to her three times a day for a week then slowly reduced the dosage to one time a day. She now does NOT cough at all. Thank you Native Remedies.”

—P. M., FL, USA

“We adopted our baby Boxer from a pet store … and used your KC-Defense, in combination with the Immunity & Liver Support (and) she was noticeably better in 1-2 days! Thank you PetAlive!”

—Sharon, MD, USA

“One of my dogs had to go for … surgery and picked up kennel cough while she was hospitalized. She obviously carried it back home and within 4 days my other 5 dogs were all coughing, sneezing and snorting with intensity of symptoms ranging from mild to quite severe. I took 2 of them to the vet to have my diagnosis confirmed and the vet suggested [medication]… I refused as none of them had high temperatures, were eating well and did not seem to be feeling desperately ill. I thought it best not to compromise their immunity …and that's when I decided to rather try the relevant PetAlive products KC–Defense and Respo-K. I also gave them a natural human cough syrup …Within 24 hours the symptoms were dramatically reduced, 3 days later only one (my oldest – 10 years of age) was still coughing occasionally and 3 days it was all cleared up completely. Thank you once again for a safe and effective alternative!”


“I … have found a new way to treat… [Respiratory issues] in my dog. I will and have done everything for my dog…for it to come back within weeks and spent ugly amounts of money. I used the Native Remedies and the results were seen within 2-3 days. I give the [remedy] once a day as a preventive measure but followed instructions to the "T" in the beginning. I have told all of my friends who have dogs about this wonderful product and they immediately ordered the product online. We can sleep now and I feel better that I have finally found a product that lives to its name. You have a customer for life. Thank you so much!!!!!”
