Remember, heartworms can get up to 3 feet long.  The dog's body has to dissolve all the dead heartworms in order for your dog to test heartworm negative. This is why dogs that test a high positive for heartworm will need a little more treatment time and why we recommend the natural Kidney Rejuvenator for the more heavily infested heartworm dogs.

Kidney Rejuvenator is a natural organic remedy that can help your dog eliminate the dead heartworm from the body more quickly.  Dead microfilaria are filtered through the kidneys. Your dog's kidneys can become overwhelmed with microfilaria and not eliminate them as quickly as they should.

Kidney Rejuvenator can help eliminate toxins from the blood and cleanse the kidneys. This helps keep the kidneys healthy making it easier to eliminate the dead microfilaria and in many cases make it easier on the dog, hasten their recovery from heartworm, and help them to test heartworm negative more quickly.


Our furry friends are an integral part of our family lives.



"People who keep dogs live longer on average than those who do not. The calming influence of the company of a friendly pet reduces blood pressure and therefore the risk of heart attack."
~ Desmond Morris



"Agreeable friends - they ask no questions, they pass no criticisms."
~ George Eliot (1819~1880) English novelist



"A dog is the only thing on earth that loves you more than you love yourself."
~ Josh Billings (1818~885) American humorist



They are the best exercise therapists I know and much cuter than human physical trainers!



"A dog is not 'almost human' and I know of no greater insult to the canine race than to describe it as such. The dog can do many things which man cannot do, never could do and never will do."
~ John Holmes


People always joke that 'dog' spells 'god' backwards. They should consider that it might be the higher power coming down to see just how well they do, what kind of people they are. The animals are right here, right in front of us. And how we treat these companions is a test.
~ Linda Blair



"If you think a dog can't count try putting three dog biscuits in your pocket and then give Fido only two of them."
~ Phil Pastoret



"My furry family members are the air that I breathe and the spirits that set my heart free."
~ Wolf Creek Ranch

HWF (formerly Heartworm Free)

HWF (aka Heartworm Free) is a natural organic herbal treatment which helps your canine fight heartworm aka dirofilariasis imminitis. All natural HeartWorm Free is useful for heartworm positive dogs.

HWF (formerly Heartworm Free) may support the heart by cleaning the cardiovascular system from unwanted foreign substances.

HWF is designed for dogs. This product may help support normal cardiovascular function by detoxing foreign contaminates left by environmental stressors. HWF supports:

  • Normal circulation of the body process
  • Normal purification of foreign substances

With a natural blend of carefully selected herbs HWF may provide a natural way of helping your dog maintain optimum health by supporting normal daily functions of the cardiovascular system, and assisting the body by synergistically working with the organs to detox unwanted contaminants. An examination from a veterinarian is recommended prior to using this product.

HWF is a natural organic herbal treatment which helps your canine fight heartworm aka dirofilariasis imminitis. All natural HWF is useful for heartworm positive dogs.

HWF will help kill the heartworms slowly over a period of time allowing your dog's immune system to help eliminate the heartworm from its body. Because HWF works slowly your dog does not need to be confined, as required by traditional heartworm treatment. Your dog can continue to play as he or she normally would not allowing "over exertion" such as racing or breeding. Within weeks, you may notice an increase in energy and a decrease in symptoms such as coughing and weakness and a healthier coat.

HWF is made without Wormwood and Black Walnut. Wormwood has been known to depress the central nervous system and can cause mind-altering changes leading to psychosis when used over long periods of time (usually months). Black Walnut was found to be a high allergen causing hives and other types of allergies. With this information, Amber Tech developed This natural HWF that (in the long run) may be more beneficial to your dog.

MUST READ: Killing heartworms can be dangerous for your dog. Dead worms can clog small blood vessels causing organs to fail making it imperative that your animal be confined to a small space to try and prevent this from happening. Older, sick, or pregnant animals may not be able to tolerate traditional veterinary treatment and some dogs are simply sent home to die without care, as the traditional heartworm medications would kill the dog. This is why HWF was created. HWF's slow method of heartworm treatment has its benefits, which allows the dog to recover slowly. HWF works well for all dogs, young, elderly, and is safe enough to give to pregnant dogs. (During pregnancy give half doses of HWF; after giving birth they can be given full dose.)

Keep in mind you are working with heartworms. The heart is a vital organ. Whether you use choose to use traditional heartworm treatment or natural heartworm treatment for your dog, there are risks. Anytime you work with the heart you take a risk. The heartworms can dislodge and go anywhere in the system. The heart can become weakened from the heartworms. Heartworms can get up to 3 feet long. If a dog is harboring a 3-foot long heartworm the time to rid the body of heartworms can be 36 weeks or longer. The severity of the heartworm infestation and condition of the heart will determine the results with the HWF treatment. Amber Tech does NOT guarantee the health of your dog, due to conditions out of Amber Tech's control.

Wolbachia Bacteria and Heartworm Treatment:

It has been found that heartworms and many other parasites depend on the Wolbachia Bacteria for survival. This bacteria enables the parasites to reproduce. It is now recommended in traditional, as well as alternative treatment to first combat the bacteria for better results in eliminating heartworms. It is now suggested that before starting the HWF, that Vibactra Plus should be administered for 30 days.

What is Wolbachia Bacteria (sort of like bacteria, but not exactly)?

Wolbachia is actually an organism; Wolbachia is a genus of rickettsial organisms. (A more commonly know genus of rickettsial organisms are the cause of tick related diseases, such as the Spotted Fever Diseases). The Wolbachia is an organism that lives inside of the adult heartworms. Although the veterinarian community is just beginning to understand the role this bacteria plays in the heartworm lifecycle it has been found that these organisms seem to be protective or beneficial to the life of the heartworms.Wolbachia bacteria plays key role in their ability to reproduce. The veterinarian community has found that treating with an antibiotic, either before treatment or during treatment, seems to sterilize the female heartworms. The role of this organism is still being investigated.

Wolbachia Bacteria and Heartworm Treatment:

It has been found that heartworms and many other parasites depend on the Wolbachia bacteria for survival. Due to the organisms protective characteristic it is thought that Wolbachia may be the cause of blood clots and the potential shock involved in traditional heartworm treatment that results when the heartworms die. Research also indicates that Wolbachia worsens the effects of the heartworms in the body and contributes to the allergic reactions and/or inflammation caused by the heartworm infection.

When using the traditional adulticide, Immiticide, many vets have begun administering a 30 day pre-treatment of Doxyclycline, this has been found to destroy the Wolbachia prior to beginning treatment. This pre-treatment also seems to weaken the heartworms and lessen the chances of blood clots. Due to the shortage of Immiticide, many vets have been treating heartworms with a combination of Ivermectin and Doxycycline, which is a slower method, but still involves harmful insecticidal chemicals. Ivermectin kills the microfilaria in the system and the Doxycyline weakens the adult heartworms. We now suggest doing a 30-day pre-treatment with Vibactra Plus, before starting the HWF. HWF has always been a safe, effective way of treating heartworms. The addition of Vibactra Plus to the treatment plan may increase the effectiveness, as well as make the treatment an even safer process. In addition, the antioxidant properties of Vibactra Plus can help to boost your canine's immune system to guard against the effects of heartworm die off.


Maintenance (Preventative Use) ~ Before beginning the Maintenance Program have your canine tested for heartworms. If your dog tests negative, then you may begin the Maintenance Program.

Directions: Shake well, use the supplied syringe. Select proper dosage from chart above; give 1 time daily for 7 days, repeat one week on and one week off, continually.

Continue yearly heartworm testings.

Basic Detox (Low to Medium Positive)

Suggested Products for Basic Detox:

Step 1: Start the Vibactra Plus 4x daily for 30 days. After the 30 days, discontinue use.

Step 2: After you have discontinued the Vibactra Plus, start the HWF Basic Detox for 16 weeks. (If using Kidney Rejuvenator and/or Hawthorn & Dandelion, start now.) Administer HWF twice daily, according to dog's weight, see chart above (once in the morning and once in the evening). After administering HWF for 9 weeks, your dog needs to be tested for live microfilaria. If your dog tests negative for live microfilaria, continue the HWF for 7 more weeks, same dosage, twice daily; total of 16 weeks detox, then proceed to Step 3. (If your dog tested positive for live microfilaria, please see the Premium Detox instructions.)

Step 3: For Basic Detox, after 16 weeks total, administer 1/2 dose of HWF, once daily (example: if your dog's dosage has been 1.0 ml twice daily, cut to 0.5 ml once daily). Administer this dose for 8 weeks. At the end of the 8 weeks, add the Life Cell Support, administering at the recommended dosage for your pet, once a day (preferably at night) AND the 1/2 dose of HWF once daily (preferably in the morning).

Premium Detox (High Positive) Premium Detox is to be done with dogs who have either tested high positive for heartworms OR started with the Basic Detox and were still positive for live microfilaria at the 9 Week testing.

Suggested Products for Premium Detox:

Step 1: IF your dog tested high positive for heartworms, start the Vibactra Plus 4x daily for 30 days. After the 30 days, discontinue use. (For dogs that started with the Basic Detox skip this step.)

Start by giving amount per weight (see chart above) 2 times daily (once in the morning and again in the evening), increase the amount given by 0.1 ml every other day until amount given is doubled. Once the dosage is doubled start Step 2. (If you have been using Hawthorn & Dandelion and/or Kidney Rejuvenator, continue using these products at their normal dosage).

Step 2: Administer the doubled dosage of HWF twice daily, After administering the double dose of HWF for 9 weeks, your dog needs to be tested for live microfilaria. If your dog tests negative for live microfilaria, continue the HWF for 7 more weeks, at the same dosage, twice daily; total of 16 weeks detox (at the doubled dose), then proceed to Step 3. (If your dog is still testing positive for the live microfilaria, please call us).

Step 3: For Premium Detox, after 16 weeks of the double dosage, administer 1/2 dose of HWF, once daily (example: if your dog's dosage has been 1.0 ml twice daily, cut to 0.5 ml once daily). Administer this dose for 8 weeks. At the end of the 8 weeks, add the Life Cell Support, administering at the recommended dosage for your pet, once a day (preferably at night) AND the 1/2 dose of HWF once daily (preferably in the morning). Continue administering the two products for 4 weeks. At the end of this 4 week period, please take your canine for testing, at this point all dead heartworms should be flushed from the system, your dog should now be Heartworm Free. Now is the time to put your pup on a preventative program. If you would like to continue using HWF as a preventative, please see the maintenance (preventative) protocol above.

*Note: It is advised to give HWF 20-30 minutes before food. If you find that your pup gets an upset stomach from the HWF on an empty stomach, you may feed a small amount of food before administering. If you have a pet that is extremely difficult to dose, have a yummy treat ready to give immediately after administering the HWF, eventually they may equate the HWF dose with something yummy, a readily take the HWF. If this does not work, you may mix the HWF in a small amount of beef or chicken broth, tuna water or a small amount of food, only enough that the pup will ingest in its entirety and not walk away from, you want to make sure that they get the entire dose. Best usage is without food.

Caution: Safe use in pregnant animals or animals intended for breeding has not been proven. If animal's condition worsens or does not improve, stop product administration and consult your veterinarian. An examination from a veterinarian is recommended prior to using this product.
