Dogs and Worms

Dog Worms

Dog worms are a nasty subject, but if you’re a dog owner and lover like I am, you have to face the subject, especially if you want to have a healthy pet for a long and loving relationship.

On this page, I’d like to introduce you to the different types of dog worms, their photos, their symptoms, what is commonly used as pet meds for dog worms, their side effects, and a better / healthier safer way to treat dog worms than the synthetic poisons pharmaceutical companies call dog worm medicine.

Please notice that this pug picture of MINE has been used by ME since 2007. I am very disgusted seeing the amount of authors that have no imagination stealing this image and using it for their site about dog worms! If you see this image elsewhere, you will immediately know that the website should NOT be trusted, as they have plagerized me.


Are above all, the most dangerous type of dog worms.

Untreated heartworm disease results in death.

Conventional treatments for heartworms may also result in death.


When an infected mosquito bites your dog, it transfers it’s larvae to the dog’s tissues, and then the heartworm larvae migrate and travel in the dog’s body for about four months before reaching the dog’s heart and lungs.

The only other way a dog can get the heartworm disease is through blood transfusions.

BUT… Female dogs can pass the heartworm larvae to her unborn puppies through the placenta, making the puppies ‘carriers’ of the disease and at a higher risk for a severe reaction to conventional heartworm medicine. The larve are in the puppies bodies, but cannot grow into adult heartworms, because they need to pass through a mosquito to become infective.

During the early stages of heartworm disease and infestation, there may be only a few, if any symptoms to let you know your dog is ill.

As the larve migrate closer to the heart, symptoms start showing, which include coughing, weight loss, lack of energy and breathing difficulties. In severe heartworm cases, a dog will cough up blood because the pulmonary blood vessels have been ruptured.

Dogs can be infected with 1 to 250 heartworms at a time. The higher the number of worms, the more severe the disease, and the greater the risk for post-treatment complications.

The heartworm larvae mature into adults during the next two to three months. Adult heartworms are 7″ to 11″ long and live in the right heart, pulmonary arteries, and vena cava.


This video on the treatments of heartworms by a veternarian mentions the dog owner using “preventatives”. “Preventatives” have very harmful side effects. A bit farther below on this page I list those side effects.



What If I Suspect My Dog

Has Heartworms?

Well, first off, you’re in for an expensive heart-wrenching journey. Your doggie needs to be tested by your veternarian, who will do a pre-treatment evaluation and diagnostics to try to determine if your pet has any risk factors that would/could increase complications to the heartworm medicines they’ll administer. There is no diagnostic test can definitively predict by 100% if your dog will have a toxic reaction to a vet’s heartworm treatment.

If a dog tests positive for heartworms after pre-treatment tests, the veternarian administers two intramuscular injections of Melarsomine, given 24-hours apart, in the muscles next to the lumbar spine. The side effects of these injection is an inflammation that will usually diminish within three days.

You must keep your dog as quiet and inactive as possible for 4 weeks after the first 2 injections of Melarsomine because of, and due to, the dying adult heartworms…. your dog has blood clots and lung inflammation. In severe heartworm disease cases, the blood flow to the outermost sections of the lung is cut off, which causes that part of the lung to be nonfunctional.

Other serious and fatal complications can occur, like: heart failure, liver disease, clotting disorders and Caval Syndrome. Caval Syndrome is caused when too many adult heartworms are in the right heart and the main vein that drains blood from the body back to the heart. To avoid death, surgical removal of as many adult heartworms as possible is done immediately. Once the dog has recovered from surgery, they are then treated with the drug Melarsomine.

You have to take your dog back to the veternarian 3 weeks after they’ve been treated for heartworms to be tested for the presence of heartworm larvae and antigens.

If the results are positive for heartworm larvae, they are injected again with Melarsomine, (the 3rd time) and require you to bring your dog back to be tested again in another week.

Your dog should be clear of the heartworm antigen by 12 weeks after treatment. Up to 20% of treated dogs may still be positive at this stage. A positive test may simply indicate that the dog has not yet cleared all of the antigens from its blood.

If they test negative of heartworm larvae on your return visit, the veternarian will normally prescribe the chemically based heartworm medicine known as Heartgard.

There are about 3,000 species of mosquitoes, and over 70 of them can cause a dog to get heartworms!

How Do I Protect My Dog

From Mosquitoes So They

Won’t Get Heartworms?

Well, that would be a pretty tough job wouldn’t it? Especially since your pets need to go outside to play, exercise, and relieve themselves! The recommended practice to protect your dog from heartworms is to administer a preventative pet medicine before, during, and 3 months after mosquito season. Many pet health specialists are now recommending the pet meds be administered year round.


The Heartworm Medicine

Marketing Lie

The heartworm medicines on the market say they’re ‘preventatives’, giving you the impression that if you buy them, they’ll ‘prevent’ your dog from getting heartworms. That is a creative marketing LIE.

They do not ‘prevent’ your dog from being bit by an infected mosquito, which results in heartworms.


Conventional Dog Worm Medicines

Contain Pesticides!

The synthetic heartworm preventative medication that you receive from veternarians called Heartgard®, Sentinel®, Revolution®, Interceptor® and Iverhart™ do not prevent a heartworm infestation.

Those medicines are a way of killing off the heartworm larvae circulating in your dog’s body during the early stages – hopefully before they get to their adult stage and infest your dog’s heart.

One of them even states that it cannot kill all the heartworm larvae!

The chemicals used in these heartworm medicines are pesticides

Although they are used preventatively in small amounts, because they are administered regularly month after month, the damage to your dog’s system is cumulative.

Regular use of these pesticides that are marketed for dog worms and heartworms can weaken your dog’s immune system and place strain on their kidneys and liver. This results in greater susceptibility to infection and other diseases. Many holistic vets are of the opinion that long-term use of these dog worm prevention medicines is one of the factors in the development of diseases like skin allergies, arthritis, liver and kidney diseases and even some forms of cancer.


The Side Effects of

Dog Worm Medicines

To prove my point, I’ve listed the most popular dog worm pet meds, with their harmful side effects. I think it is absolutely horrible that we subject our beloved companions to the possibility of experiencing any of the side effects of these synthetic drugs!


Just in case you didn’t notice the last time you bought Heartgard®, it’s other name is Ivomec®, and Ivermectin®; a chemical that contains pesticides.

The National Poisons Control Center is regularly contacted about Ivermectin overdose in dogs.

Heartgard side effects include: stumbling, tremors, blindness, disorientation or weakness, and shock. Other side effects of Heartguard may include weakness, vomiting, convulsions, and diarrhea.


The pet medication called Revolution® for fleas and heartworms is derived from the ingredient of Selamectin. A member of the Avermectin class of insecticides, and is closely related to Ivermectin (heartgard).

Revolution is not effective against adult heartworms, it only treats the heartworm larvae. “while the number of circulating microfilariae (heartworm larvae) may decrease following treatment, Revolution is not effective for microfilariae clearance.”

Revolution side effects include: hair loss or skin irritation at the application site, excessive drooling/salivating, rapid breathing, lack of coordination, vomiting, diarrhea with or without blood, muscle tremors, lethargy, loss of appetite, itching, hives, fever, seizures, and in rare but reported incidents of death.


Interceptor® is another pet med for heartworms with the ingredient of Milbemycin Oxime. It is not effective against adult heartworms, it only treats the heartworm larvae. Interceptor claims to also rid your dog of adult hookworms, roundworms, and whipworms.

Interceptor side effects include: depression, labored breathing, lying down and unable to rise, lethargy, coughing, vomiting, excessive salivation, staggering, shock, seizures, loss of appetite, diarrhea, convulsions, scratching, hives, facial swelling, pale gums, cold limbs, and coma.


Sentinel® pet medicine consists of Milbemycin oxime and Lufenuron, marketed for fleas and heartworms. If you’ve noticed, Milbemycin oxime is the ingredient of Interceptor.

So, the side effects of the Milbemycin oxime in Sentinel are: depression, labored breathing, lying down and unable to rise, lethargy, coughing, vomiting, excessive salivation, staggering, shock, seizures, loss of appetite, diarrhea, convulsions, scratching, hives, facial swelling, pale gums, cold limbs, and coma.

Add to that, a double dose of side effects of Lufenuron: lack of appetite and anorexia, vomiting, diarrhea, convulsions, lethargy, difficulty breathing, itching, hives, seizures, and weakness.


Iverhart™ ingredients are Ivermectin and Pyrantel. Marketed for the treatment of heartworms, roundworms, and hookworms. Ivermectin is the pesticide ingredient in Heartgard.

Ivermectin side effects are: stumbling, tremors, blindness, disorientation or weakness, shock, weakness, vomiting, convulsions and diarrhea.

Pyrantel is a drug for roundworms and hookworms, with the side effects of: upset stomach, vomiting, diarrhea, loss of appetite, stomach cramps, stomach pain, and straining and pain during bowel movements.

Customer Testimonials of this Natural Dog Worm &

Heartworm Pet Medicine

“I have a Min Pin, 8 years old. For the last 6 months he has not barked at all, wheezes and I figured he may have heart worms even though he is on Heart Gard. I gave him your Parasite Dr. for the past 2 weeks. I am thoroughly amazed. My dog is alive and barking as loud as he can. He looks and acts totally different. I am totally amazed at your product and recommend it HIGHLY to anyone who suspects their dog has a parasite.” Jan

“I recently had a 4 year old female rough collie given to me. When I got her, her fur was thin and brittle, her bones stuck out everywhere and generally presented a very sick animal. I took her to the vet who told me she had a very advanced case of heartworm. They wanted to treat her with two injections given a couple of weeks apart, but wanted to keep her there. Since I have other animals that I care for, funds were limited and the vet didn’t seem to think she would live. So, I took her home and got on-line. I found your site and ordered your Parasite Dr. capsules. After 4-6 weeks, her fur is coming back in and her weight started increasing after the third week. The difference is amazing and I wanted to share this with you. I give the capsules to all my dogs. Thank you for an alternative remedy that is not only better for the animal, but, less expensive. Thank you again, and I am now a loyal customer.” Sheryl

“I have never liked the idea of the chemical products for de-worming my animals, but there did not seem to be much choice! Thanks for providing an effective alternative!” Cindy B.


Information About Other Dog Worms


Dogs get tapeworms by swallowing a flea that contains tapeworm eggs. As the flea is digested within the dog’s intestine, the tapeworm hatches and anchors itself to the intestinal lining.

Occasionally, the mobile segments can be seen crawling near the anus or on the surface of a fresh bowel movement. These segments look like grains of rice and contain tapeworm eggs; the eggs are released into the environment when the segment dries. The dried segments are about 1/16″, hard and golden in color. These dried segments can sometimes be seen stuck to the hair around the dog’s anus. tapeworm

Tapeworms are not highly harmful to your dog. Tapeworms may cause debilitation and weight loss when they occur in large numbers. Sometimes, the dog will scoot or drag its anus across the ground or carpet because the segments are irritating to the skin.

Occasionally, a tapeworm will release its attachment in the intestines and move into the stomach. This irritates the stomach, causing the dog to vomit the worm. When this happens, a worm several inches in length will be seen.

Control of fleas is very important in the management and prevention of tapeworms. If the dog lives in a flea-infested environment, re-infection with tapeworms may occur in as little as two weeks.




Roundworms are infectious to people. As many as 10,000 cases of roundworm infection in humans have been reported in one year. Children, in particular, are at risk for health problems should they become infected with roundworms. In suitable environments, the roundworm eggs may remain infective to humans (and to dogs) for years.


As their name implies, these are dog worms which have round bodies. On average, they are about 3-5 inches (7-12 cm) long. They live in the dog’s intestines and consume partially digested food. Roundworms eggs can be found with a microscope in the dog’s stool.

Examination of more than one stool sample may be necessary the eggs, and occasionally the mature worms can be found in the dog’s stool or vomit.

Some signs of a roundworm infection are weight loss, decreased appetite, vomiting, diarrhea, a pot-bellied appearance in puppies, and a weak appearance in adult dogs. Puppies can die with serious roundworm infections.

Prompt disposal of all dog feces is important, especially in yards, playgrounds, and public parks. Strict hygiene is especially important for children. Do not allow children to play in potentially roundworm contaminated environments.

Roundworm eggs passed in one dog’s stool may be infectious to other dogs. A large number of other animal species have been found to harbor roundworms and represent potential sources of infection. These include cockroaches, earthworms, chickens, and rodents.

Both puppies and adult dogs can become infected by swallowing roundworm eggs which contain infective larvae. The larvae hatch out in the dog’s stomach and small intestine and migrate through the muscle, liver, and lungs. After several weeks, the larvae make their way back to the intestine to mature. When these dog worms begin to reproduce, new eggs will pass in the dog’s stool, and the life cycle of this parasite is completed.

Puppies born to mothers that have had roundworms at any time in the past can transmit them to their puppies before birth. Puppies can also get roundworms through their mother’s milk. Roundworm larvae may be present in the mother’s mammary glands and milk throughout the period of nursing the puppies.




Dogs may become infected with hookworms in 4 ways: orally, through the skin, through the mother’s placenta before birth, and through the mother’s milk.

The side effects of a hookworm infestation include intestinal distress, weight loss, bloody diarrhea, failure to grow properly for puppies, and anemia.

Signs of anemia in dogs are: pale gums and skin, exaustion, panting, general discomfort, lack of appetite, and mental dullness. Anemia can only be reversed through a blood transfusion or the drug Oxyglobin. Oxyglobin is administered intravenously. Oxyglobin side effects are coughing, difficulty breathing, fluid retention in the lungs, fluid in the chest cavity, vomiting, and dark colored feces.

Skin irritation and itching can be one of the common signs of a hookworm infested environment. The hookworm larvae burrow into the skin and cause the dog a great deal of itching and discomfort.

This dog worm gets it’s name from the hook-like mouth parts they use to attach to the intestinal wall. They are only about 1/8″ long, but despite their small size, they suck large amounts of blood from the tiny vessels in the intestinal wall.


Hookworms are diagnosed with a microscopic examination of a small stool sample. One adult female hookworm is reported to produce as many as 20,000 eggs a day. In puppies, large numbers of worms usually must be present before the hookworm eggs are shed into the stool. For this reason, fecal examination may be less reliable in very young puppies than in adult dogs.

Prompt disposal of all dog feces is important since the dog’s environment can be laden with hookworm eggs and larvae. Hookworm eggs passed in one dog’s stool may be infectious to other dogs.




Any dog with chronic diarrhea can be reasonably suspected to have whipworms, regardless of several negative stool examinations.

Whipworms are 1/4 inch long, and live in the cecum and colon of dogs where they cause severe irritation to the lining of those organs.


Some signs of whipworm infestation is watery, bloody diarrhea, weight loss, and general debilitation.

Whipworms pass microscopic eggs in the stool. The eggs are very resistant to drying and heat, so they can remain viable in the dog’s environment for years. They mature and are able to reinfect the dog in 10-60 days.

Prompt disposal of all dog feces is important since the dog’s environment can be laden with whipworm eggs and larvae. Whipworm eggs passed in one dog’s stool may be infectious to other dogs.
