Parasitic Infection Situations in Household Pets

2025-03-11T19:14:33
A parasite is an organism that can only survive off another organism, which is the host. Parasites make use of the body of the host for shelter and nourishment. These parasites rely completely on the host, as they use them as a vehicle to spread to the next potential host, where there is continuous spread and multiplication.
Intestinal parasites are very common in our most common household pets, like dogs and cats. Many of the parasites are worms and single-celled organisms that live and reproduce in the intestines. The most common types of parasites are tapeworms, whipworms, hookworms, and roundworms. We also have the single-cell parasites that are coccidia and Giardia.

Let me explain the common parasite types.

Roundworms: The large type of roundworm known as ascarids are more common in dogs, especially puppies. The most important species is Toxocara canis, this is because the infections are very common, and the larvae migrate in people too.
Situations of fatal infections can happen occasionally in young puppies; Toxocara canis happens through the transfer into the developing fetus through the placenta. This worm exists in the intestines of puppies as early as one week after birth. There is also a possibility of puppies getting infected while nursing.
Usually, an adult dog would grow resistance to an infection, but during the period of litter birth, the immunity that the female dog has previously developed to infection becomes suppressed, and the inactive larvae also become active. Therefore, crossing the placenta to the puppies and sequestering in the mammary tissue, where they get transmitted in the colostrum and milk.
As a result of the already suppressed immune system at the time of whelping, an active infection may happen in a pregnant dog, with a great number of eggs passed through their feces.
You can easily tell that there is an infection when the young animal fails to grow, has a dull coat, and usually has a potbellied appearance. There is a possibility of worms being vomited or passed through feces. Roundworm infections in their early stage of infection may cause pneumonia, which could be linked to cough. Diarrhea that contains mucus may be an evident sign of infection in cats and dogs and can be noticed through a detection of roundworm eggs in feces with the help of a microscope.

The treatment of roundworm is possible, the chances of transfer from mother to child can also be reduced greatly through the administration of antiparasitic drugs administered during pregnancy and after the birth of a litter.
The infection of roundworm from pets to humans is possible, so there is a strong need for the practice of good hygiene, prompt disposal of feces, and adequate washing of hands properly.
Moving quickly to hookworms, which are also a type of parasite that can affect pets. An infected animal would pass hookworm eggs through their feces and hatch them into the environment. When your pet swallows the larvae in a contaminated surface or substance, which could be through the consumption of an infected insect, or maybe a direct contact with the larvae can also cause infection if there is a penetration through the skin.
A female dog that has been infected can pass parasites to the puppies through her milk, but this only happens in dogs and not cats. Once there is an infection, hookworm larvae would begin to travel through the body of the infected pet.
Once they find their way to the small intestine, they attach themselves there and grow into adult worms that produce eggs. Hookworm infection is present all through the summer and fall; there is no space for a break here.
Adult hookworms can also bite into the intestinal lining of an animal and suck blood. Puppies and kittens are at more risk of getting infected and developing diseases. In an untreated case, there is a situation of weakness, poor nutrition, and blood loss that poses threats to life.
Humans can get affected too if these hookworms find their way to the skin or they get swallowed. The ones that get to the skin create a situation of serious itching.
There are medications approved for the treatment of hookworm infections, and when it is discovered that a newborn pup dies as a result of hookworm infection, other litters that come from the same mother should be treated based on instruction from the veterinary doctor.
Whipworms: Adult whipworms are Trichis vulpis. In dogs, they are mostly found in the cecum and colon, which is a part of the large intestine. They have a way of attaching themselves strongly to the intestinal walls and are passed out in the feces, then become ineffective at 4-8 weeks.
Under normal conditions, the eggs of whipworms can remain dormant in the environment for years unless they dry out. Once these ineffective eggs lying around are ingested, larvae begin to develop in the small intestine and then move to the cecum and colon, where the adults become mature.
When the infection is still at the light stage, no sign is seen, but as the number of worms increases, the colon and cecum can also become inflamed; this can cause weight loss and diarrhea. Fresh blood may be seen in the feces when there are heavy infections, and this may lead to anemia.
It takes around a month for whipworms to become ineffective, so it can be controlled with proper sanitation. When the pet is kept in a clean environment, the chances of infection are reduced.
Tapeworms are of different types; they are known as cestodes and may infect dogs. Adult tapeworms are segmented worms that are found in the intestines of dogs, and they most likely wouldn't cause any serious disease.

Most home-trained dogs who eat prepared meals and have restricted access to outdoor exposure may acquire Dipylidium caninum, which can be gotten through the consumption of fleas.
But, on the other hand, those hunting dogs that have access to other small mammals can be exposed to different species of tapeworms. An infected dog may not be able to digest and absorb food properly. It would be irritable, have a shaggy coat, mild diarrhea, and a variable appetite.
Tapeworm infection requires treatment and prevention. Flea control is important for indoor pets; roaming dogs would most likely pick up tapeworm infections from time to time.
The most important way to protect your pet from these parasites is to ensure a clean environment, and the practice of good hygiene must be ensured. I believe this is enough information on this topic, thank you for reading, and I will see you next time.
