You might think that worming puppies is simple. Give the pups some worming medicine and all is right with the world. Well, sorry to inform you, it is not as easy as it sounds.
I have been worming puppies for a very long time, mostly as a breeder but also as a puppy parent.
It's not rocket science, but it is important to get it right because internal parasites can wreak havoc in your little baby, whether he's a puppy or a ten year old.
This article is intended to help other breeders as well as puppy parents deal with those pesky parasites and keep your fur friend happy and healthy.
In this article, I will be touching on a number of very important concepts that pertain to worming puppies.
Types of Parasites
Puppies and adult dogs can get parasites both internally and externally. We think of external parasites as fleas, ticks, lice, and mites, those tiny creatures that make their homes on the skin of our furbabies. External parasites are an entirely different ballpark and won't be covered in this article.
Internal parasites, those that reside within our four legged friends is what we will be discussing. Just the though of having something living inside another creature can give even the strongest among us can keep us up at night.
Simply put, according to the Center for Disease and Prevention,
There are others, but they are not as common in the northern hemisphere so we will address the most common ones.
Most pet parents are aware of the potential of their pets to acquire heartworm disease. Conscientious parents give their dogs a preventative monthly to protect their dog form the potentially fatal disease.
Heartworm disease is serious and sometimes fatal problem in dogs, cats, and ferrets but can also affect other wild animals including foxes and coyotes.
An adult dog with heartworm disease can have hundreds of adult worms living in their heart, lungs, and the associated large blood vessels around these organs.
Heartworm disease starts when a dog is bitten by an infected mosquito. The baby or larval stage of the heartworm grows to the adult stage within 6 months.
According to the Heartworm Society, an infected dog will show signs such as:
Luckily, this is a preventable disease. Dogs should be put on a heartworm preventative at the recommendation of their veterinarian. This preventative medication requires a prescription and all dogs over 7 months of age will also need a yearly heartworm test.
The American Heartworm Society recommends that puppies and kittens be started on a heartworm preventive as early as the product label allows, and no later than 8 weeks of age.
According to the Companion Animal Parasite Council (CAPC), the prevalence of hookworms in the U.S. in 2018 is 2.96%. In Canada the rate is 1.57%. That may seem low, but hookworms can wreak havoc with your dog's health and you can also be infected.
Most hookworm infestations occur in warmer climates but no location is immune. This parasite attaches itself to the intestinal wall and sucks the blood of its host. This is particularly problematic in puppies because they can't survive the blood loss.
Adults fair better but still show chronic signs of anemia, diarrhea and weight loss. Eggs are then passed through the GI tract and hatch into a larvae stage which can live in the soil. A dog can come into contact through eating the larvae directly from the soil or licking their skin or through penetration of the skin. The life cycle begins again.
People can get hookworms, but normally by walking barefoot on a beach or on contaminated soil - not directly from their dog.
Roundworms are the most common type of worm found in the dog. It is believed that almost all dogs become infected at some point in their life and often that occurs in puppyhood. They spread easily and are hard to control without worming.
Most puppies are infected with roundworms from the time they are born because the mother passes the worms onto her babies while still in the uterus and then can also be infected through the mother's milk.
Most dogs don't show signs of the worms but some may show the characteristic signs of diarrhea, vomiting, dull hair coat, weight loss and that pot bellied appearance. Puppies can also cough up worms if they pass into the lungs. You can sometimes see the worms if they pass through the dog's feces. They will be a few inches long and resemble spaghetti.
Breeders routinely worm puppies at two week intervals beginning at 2 weeks of age. Nursing moms can be wormed at the same time, but if adults are kept on a monthly heartworm preventative, the medicine will not only control heartworms but also round and hookworms.
Contact with contaminated soil or dog feces can poses a risk to people where children are at the greatest risk. Children should not play in areas soiled with feces. Roundworm infections in people can cause eye, lung, heart and neurological symptoms in people.
What are They, Where do they Live?
There are four major worms found in dogs and whipworms are one of them. These worms occupy the area between the small and large intestines called the cecum. An adult whipworm is about two inches long and tapered at one end making it look like a whip.
How do Dogs get Infected?
The main way that dogs can get infected with whipworms is when they swallow whipworm eggs found in soil, water, or other substances containing dog feces.
What are the Symptoms?
Whipworms are not as big a problem in healthy adults but puppies, seniors, and immune compromised dogs can show symptoms and even death can occur. Symptoms to look for include diarrhea, sometimes bloody, vomiting, weight loss and anemia.
How are They Identified?
Veterinarians can detect the eggs of the whipworm during a routine fecal exam. A fresh sample is necessary.
How to Prevent a Whipworm Infection
The best way to prevent a dog from becoming infected with whipworms is to avoid areas where your dog can come into contact with fecal material.
What are Tapeworms?
Tapeworms are long flatworms with segmented bodies that can break apart and the pieces can pass in the dog's feces.
How do Dogs Become Infected?
The main way that dogs get tapeworms is by eating an intermediate host that carries the worm. Fleas are a common intermediate host so if dogs have fleas, they can lick or bite at the fleas and thus ingest the larval form of the parasite. They can also get tapeworms from eating the raw meat of other animals.
Dogs that Eat a Raw Diet
According to Dog Naturally Magazine, those folks that feed a raw diet should freeze the meat for 10 days before feeding it to their dog.
A common misconception about tapeworms is that they cause a dog to scoot on the ground. Scooting can be a medical problem but it doesn't have anything to do with tapeworms.
Most people will identify the presence of tapeworms in their dog by observing the feces. Each body segment of the tapeworm will look like individual grains of white rice. Other signs to look for include a dull coat decreased appetite and weight loss.
The best prevention is flea control. Some heartworm preventatives also kill tapeworm infections.
What are they, and Where do Coccidia Live?
Coccidia are microscopic single celled organisms that live in the wall of your dog's intestine. While more common in puppies, they can also infect older dogs.
How do Dogs become Infected?
They become infected by eating something containing the coccidia such as soil, grass, or contaminated surfaces.
Coccidiosis is the disease name that is caused by the coccidia parasite and is more serious in young puppies. The main symptom is diarrhea, sometimes bloody diarrhea, dehydration and weight loss Very serious cases can be fatal.
Surveys indicate that coccidia are present in from 3% to 38% of dogs in North America.
What are they and Where do they live?
Like Coccidia, Giardia are one celled parasites that can be seen only with the help of a microscope. They live in the intestines of the dog.
How do Dogs become Infected?
Dogs, especially puppies pick up the giardia organisms by drinking contaminated water or eating the feces or contaminated surfaces such as grass or soil.
What are the Symptoms?
Not all dogs that infected with Giardia show any symptoms, but those that do, especially puppies will have diarrhea watery with mucus), weight loss, poor condition and even death. The severity of symptoms depends on the amount of parasite, stress, nutrition and immune status.
The Giardia cysts are passed in the feces and can live for months outside the host in cool, moist conditions but survives for only a short time, in hot, dry weather. It is normally seen during the fall through spring but less common during the summer unless there is standing water that hhas been contaminated.
Giardia is very hard to get rid of and may require more than one round of treatment. It is also easy for your dog's environment to remain contaminated so he gets infected again.
Giardia is also hard to detect with a simple fecal test. Specialized Giardia ELISA tests may be required.
Unfortunately there is not a medicine that will take care of all worms. Before you begin a treatment program is is best to know what worms a puppy may be harboring. This is the main reason why veterinarians ask for a fecal sample when bringing in a new puppy for the first time.
NOTE to BREEDERS
Breeders should plan to worm their puppies beginning at 2 weeks of age and continue until the puppy goes home. Check with your vet for his/her recommendation for worming puppies. There will be differing opinions among veterinarians.
Dog breeders may prefer this product over the one previously mentioned as it is cheaper to worm an entire litter along with the dam. Used in multi-dog households, rescues and shelters
This is one of the most popular worming medicines for treating roundworms and hookworms in puppies as young as 2 weeks old.
It is easy to dose even tiny puppies using either an insulin or 3cc syringe.
In addition, this is a liquid formulation, the dose being 1 teaspoon per 10 lb body weight. Use a 1 ml or 3 ml syringe to administer worming medicine.
1 ml Syringes
3 ml Syringes
Many breeders prefer this medicine over the Nemex-2 because it is more economical. Note, the dosage for this medicine is NOT the same as the Nemex-2
This product is an alternative to the other worms that use chemicals to remove worms. Naturepet D Wormer uses all natural ingredients.
Albon (sulfadimethoxine) is the only FDA approved drug, for treating Coccidia. It is a prescription antibiotic drug. It is used for the treatment of certain bacterial infections as well as treatment of coccidiosis, and the most commonly prescribed medication for Coccidia in the U.S.
It comes in both pill and liquid form. There is no generic form as of this writing and will require the prescription from a licensed veterinarian. This medication does not kill coccidia but prevents it from reproducing.
Toltrazuril (Baycox) – This is labeled for treating coccidia for poultry. Used as an alternative treatment for coccidiosis in dogs and cats, and the oocyte shedding stage of toxoplasmosis in cats. Not commercially available in the US, but can be imported and does not require a prescription
Metronidazole (Flagyl) – This drug is an antibiotic that is also used to treat infections such as Giardia, in dogs. It is a prescription medication but can be obtained over-the-counter as Fish Zole (a medication sold as a fish antibiotic).

Hygiene is important to prevent re-infetion. Several methods are required:
1. Clip hair around the hind end
2. Whip with baby wipes after defecation
3. Routine bathing
4. Pick up stools immediately
5. Steam clean hard surfaces
6. Quaternary ammonium disinfectants
1) Hygiene is critical to prevent re-infection – clipping hair around the hind end, wiping with baby wipes after defecation, routine bathing, pick up stool immediately, steam clean where possible or use quarternary ammonium disinfectants, do not allow access to an area where infected stool has been to prevent reinfection.
