Dogs are mostly affected by 4 Types of Worms

 

1. Roundworms

2. Hookworms

3. Whipworms

4. Tapeworms

.

1. Roundworms (Toxocara canis)

Roundworms can live in a dog’s stomach. Their name is derived from the tubular or round shape of the worm. Roundworms can vary in color from white to light brownish, resembling a string of spaghetti as they are capable of growing to a few inches in length.

The majority of dogs will be infected with this type of worm at some stage in their lives but it is more common with puppies. Unfortunately, puppies are more at risk from roundworms as they stunt their growth and development. These worms exist by surviving on partly digested food in the gut, thereby depriving your fur baby of essential nutrients that can result in malnourishment. One roundworm alone can produce over 85,00 eggs in one day so vital to eliminate these worms before it escalates into a serious infestation.

 

What Type of Roundworms Can Dogs Get?

There are 3 different types of roundworms that can affect dogs.

1. Toxocara Canis

Tocara canis is the most common type of roundworm that affects dogs and can be especially harmful to puppies. Puppies even before they are born can be infected with this worm. Even within 2/3 weeks after birth, puppies can pass these worm eggs. The particular type of roundworm is very resistant and can survive for long periods in contaminated soil.

2. Toxascaris Leonina

Toxascaris leonina is another common parasitic roundworm found in dogs, cats, and rodents. The good news here is that there is no transfer of this worm in the mother’s womb to the puppies.  It is more commonly found in cats and the main method of infection is when the host either ingests the eggs or consumes an infected rodent.

3. Baylisascaris Procyonis

The Baylisacaris procyonis roundworm is found moostly in raccoons and consequently there is a low level of infection rate in dogs in comparison to other worms.

Dogs are mostly infected by this worm through soil that was infected where raccoons defecate. If your dog walks through an area that has been contaminated by racoon feces and then later cleans himself then unfortauntely he can ingest the worm eggs and the infection begins. The more raccoons in an area the higher the risk of infection.

The most prevalent rate of infection occurs in the Northeast and Midwest and the West Coast where it is estimated 70 to 100% of raccoons carry this roundworm. Lower rates are noticeable in the deep south and along the Carolinas and Florida. The consequences of infection with this particular parasite can be fatal. It is similar to rabies in that it can cause fatal neurological diseases in both humans and dogs.

 

How Do Dogs Get Roundworms

An article from the US National Library of Medicine National Institutes of Health Pet roundworms and hookworms stresses the need to keep our guards up against these types of parasites. The major parasitic roundworm affecting dogs in the world is the Toxocara canis.

1. Pregnant / Nursing Dogs

One of the main ways puppies are infected with worms is through a pregnant or a lactating dog. Unborn puppies can be infected while still in the womb during the gestation period and also when they are born there can be worm eggs in the mother’s milk.

Once a dog has been infected with roundworm it can still retain somatic larvae. The larvae can spread to different parts of the body and can be reactivated in the last 2/4 weeks of a dog’s pregnancy and consequently infect the puppies through the colostrum and milk for up to 38 days from birth. It can even affect up to 3 consecutive litters. This is one of the main reasons why young puppies are de-wormed after the first 2/3 weeks of life. Unfortunately, if a puppy has a high infestation level there is a high risk of death just after birth.

2. Feces

When a dog has a worm infestation there will be microscopic roundworm eggs in its feces. So when he defecates and another dog comes along and either sniffs or licks the excrement this dog can also become infected with worms.

In addition, the soil where the poo sits can also be infected with these roundworm eggs. Consequently, this can then cause other animals such as earthworms, birds, and rodents to spread the eggs and help continue the cycle of infection.

 

Can Humans Get Roundworm?

Yes, unfortunately, humans can pick up roundworms too. If you think your dog has worms give your veterinarian a call to arrange an appointment. The vet will be able to determine what type of worm from analyzing a sample of his feces.

Unfortunately, humans can pick up roundworms from dogs and puppies that have been infected. It can be quite easy to pick up some of the microscopic eggs from contaminated areas or even when your dog shows his love for you by licking. The eggs enter the body and form into larvae that can then travel throughout the human body. Sometimes they can be referred to as wandering larvae. For the majority of cases, there are no ill effects and you may not even be aware that you have been infected. However, there can be very serious consequences for some infected people, especially young children. The larvae can travel around the body and can even end up in the eye that can affect eyesight and possibly result in blindness.

 

2. Hookworms

The hookworm species hookworm affecting dogs is officially called Ancylostoma caninum. These worms are found in the small intestine and their name derives from their teeth in their mouth that attach themselves to the intestinal wall.

Hookworms are normally grayish-white to pinkish in color. They are very small in size usually around 1/8 inch (2/3 mm). Hookworms survive and thrive by feeding on blood from very small blood vessels in the intestinal wall.

 

How Do Hookworms Affect Dogs?

As hookworms feed on small blood vessels they can cause two major problems

1. Inflammation of the Intestine.
This can lead to stomach pain, cramps, and digestive issues

2. These worms feed on blood thereby making them one of the most dangerous parasites and this is particularly concerning for puppies. If there is a large infestation then it can affect the blood supply and lead to blood loss (anemia)

 

The Ways Dogs Get Hookworms?

Dogs can pick up hookworms in a number of ways. Contaminated feces on the ground is probably the most common form of transmission. Unfortunately, all a dog needs to do to become infected is to sniff or lick feces that itself has been infected with worms. Another way your dog could end up ingesting these hookworms is by your dog self-grooming after walking over a contaminated spot. Dogs often clean themselves especially their paws and can accidentally ingest these worms.

 

Can Humans Get Hookworms?

Unfortunately yes, humans can get hookworms too.

According to the Center For Disease Control, the most likely way for humans to get hookworms is by walking over an area that has been contaminated with worms while barefoot. If a dog with hookworm has left his feces in either soil or sand that area can become infected as well. Consequently, if you are unfortunate to walk over that area while barefoot there is a chance that the larvae will burrow into your skin cuasing irritation and infection.

The best way to avoid hookworms is to wear shoes, sandals, boots, or whatever protects your feet. It is also best practice to remove any feces as soon as possible from any spaces so that the eggs do not hatch and lead to further contamination.

Now here’s the gross part. The irritating part of the skin will have red and raised tracks. These tracks on the skin follow the larvae’s movement within the body and they can change daily. Now the good news is that in the vast majority of cases the larvae will die after a few weeks and the body will return to normal. Only in rare will the larvae make it to the intestine and cause stomach cramps and pain along with diarrhea.

 

3. Whipworms

Whipworms live in the large intestine. Their name is derived from their shape as they resemble the appearance of a whip – thick at one end, the posterior and long and thin at the other end, the esophagus. The color for whipworms varies from yellow to brown and they can reach about 1/ inch (6mm) in length.

How Do Whipworms Affect Dogs?

The whipworm attaches to the intestinal wall and burrows with the long thin end. When this happens it can cause hemorrhage and discomfort and irritation in the intestine.

When dogs have low levels of whipworm infection they may not show any symptoms at all and would go undetected if not tested. However, at high levels, it can produce severe symptoms including stomach pain, diarrhea, blood in the stool, and on occasions the higher the rate of infestation of worms the more severe the symptoms. If the dog has a severe case of infestation of whipworm it can cause death.

How Do Dogs Get Whipworms?

As with other parasitic worms, dogs can get whipworms from licking or sniffing another dog’s feces that contains worms or else through soil that has been infected with worms due to dog feces lying on the soil or sand.

Can Humans Get Whipworm?

The good news on this front is that humans cannot get whipworms from their dogs.

 

4. Tapeworms

Tapeworms live in the intestine of the dog and they have a ribbon-like shape and are whitish in color. They are made up of different segments and each segment is called proglottids. The official name for this dog tapeworm is Dipylidium caninum and can sometimes be more commonly referred to as the flea tapeworm.

How Do Tapeworms Affect Dogs?

The good news on tapeworms in dogs is that on most occasions they do not cause any serious problems and they can be treated quite easily. Tapeworms survive and thrive by burrowing into the walls of the intestine. They do this by using their hook-like suckers and then feed on food that has been consumed by the dog.

Now here’s the yucky part. Tapeworms can grow to very long lengths in your dog’s intestine from 4 to 28 inches! As they grow within the intestine, small segments (proglottids) of the worm, roughly about the size of a grain of rice break off.

These worm segments are not always passed in feces so it can make the task of identifying the issue more difficult for your veterinarian. However, sometimes these smaller segments of the worm can be seen even crawling around your dog’s anus or you may find dead ones in your dog’s bedding. I know it sounds nasty but it’s advisable to collect these worm segments so that your veterinarian will be able to analyze them. It’s not often you will see the adult tapeworm but it can happen on occasion.

If you ever notice your dog scooting along the floor on his backside it could be a warning sign that he has tapeworms. It can look comical but your fur baby is trying to get some relief from these pesky and annoying worms.

 

How Do Dogs Get Tapeworms?

The most common way for your dog to pick up tapeworms is by ingesting a flea that has itself been infected with tapeworm. When your dog ingests an infected flea the tapeworm can then grow in your dog’s intestine. Most dogs pick up tapeworm either from mixing with other dogs with infected fleas or when they are self-grooming themselves by licking.

 

Can Humans Get Tapeworm?

The good news is that you cannot get tapeworms directly from your dog. However, you can still get tapeworm if you come in contact with the larvae or eggs of the tapeworm. Normally the most common way for this to happen for adults is by walking barefoot through an infected area containing tapeworm eggs while out gardening. Children are the most vulnerable when playing in the garden or in a sandpit that has been infected with tapeworm eggs.

Many people who are infected with tapeworms don’t even realize it. There was recently a case where doctors removed a 6 foot long tapeworm from a man’s stomach. He was initially complaining of lethargy and an upset stomach. Only after an examination by doctors was he found to have this huge tapeworm inside his body. Yuck!


 

Warning Signs That Your Dog Has Worms

If you think your puppy or adult dog has parasitic worms you need to have a consultation with your veterinarian as to the best course of treatment.

If the worm infestation is moderate to high it can cause all types of problems. Unfortunately, there are different health issues for each worm type. Some worms can migrate through the body and can cause a cough, nasal discharge, pneumonia, and even blood loss. For puppies, roundworms as well as causing malnutrition can also stunt their development and lead to weight loss.

Some of the general warning signs for worms to watch out for include:

Weight Loss Leading to Malnutrition 

For severe infections, your dog or puppy will suffer weight loss. This loss in weight will have a detrimental effect on his health as not enough nutrition is being made available.   This will result in lethargy, weakness and your dog will have a dull coat and look unwell. In severe infestation of worms, it can even cause intestinal blockages.

Diarrhea

Dogs can experience severe bouts of diarrhea and there will be worm eggs in the poo so make sure it is cleaned thoroughly.

Potbelly Appearance

Puppies with worms can also have swollen bellies.

Vomiting

In some cases of infection vomiting and retching can occur.

Before starting any course of treatment consult with your veterinarian to find out what particular worm is affecting your dog. Dewormers are used to treat active worm infestations.  Normally they are effective with just one treatment but sometimes your dog can get reinfected so you may have to dose again around 3 weeks. The vet can advise on all these issues.
