What is a Parasite? – A Brief Overview
Parasites are creatures which have one-way relationships with their hosts meaning the parasite only stands to benefit whilst the host suffers some detriment. You can find parasites all over the natural world, inhabiting many different environments and can be types of animal (such as the parasitic worms), plant, fungi, protozoa and also microorganisms like bacteria and viruses.
Parasites that belong to the animal kingdom usually have very particular life cycles with the host normally coming into play during the reproductive stage. They can be categorized based on how they interact their host, the most relevant being:
- Endoparasites – Live within the host such as parasitic worms
- Ectoparasites – Live on the exterior of the hosts like skin and hair such as fleas and lice
- Mesoparasites – Are somewhere in between ecto and endoparasites
- Hyperparasites –Choose other parasites as hosts such as some protozoa species
- Parasitoids – Parasites which aim to eventually kill their host such as hawk wasps
Types of Parasitic Worms in Dogs
All dog owners will have heard of the main four parasitic worms that can infect their beloved canine friends and it’s no doubt a good idea to avoid them. Some fo the best dog dewormer products above can treat all four but others are not able to. Now is the time to get acquainted with them, learn what they’re all about and how to spot them.
Tapeworms are a type of flatworm. There are many species of tapeworm but they all have a lot in common. Tapeworms are white in color, flat in shape and consist of many segments which make up their body. They are probably the most famous parasite found in pet dogs as they are able to also infect humans and there is a fear surrounding cases in which they can form cysts around the Human brain.
Their lifecycle consists of the eggs entering the system of an intermediate host (the flea) which then hatch into the first stage of their development; their juvenile form. They then rely on entering the digestive system of your pet in order to grow into adulthood and attach to their GI tract using their sucker-like mouthparts. They then create more eggs (cysts) which exit through your dog’s feces to continue the cycle.
Detection and Symptoms
As the adult worms live in your dog’s digestive tract they sometimes shed segments which can leave through their rear alongside the eggs and so the most obvious symptom is spotting this evidence in your dog’s poop. Bear in mind that the cysts and segments are not always passed so it may require you pay attention every time if you are suspicious of infection.
The segments and cysts are white-yellow in color, the eggs looking similar to grains of rice and they may irritate your dog resulting in them dragging their behind across the floor; a very telling sign in itself.
If left untreated for some time, your dog could experience quite considerable weight loss and will also have a strong appetite due to the worms consuming the food your dog eats. They may also cause your dog to throw up and that might even reveal adult worms in the vomit which are usually between 5 and 8 inches long.
A key prevention technique is to ensure you also prevent fleas as they are the intermediate host the worm uses to infect. Make sure to keep flea spray, powders, collars or your preferred anti-flea and deworming products to hand.
Also, ensure to always remove your dog poop form your yard and especially from public areas to prevent the infection from spreading between dogs. A good community standard through awareness is the best way to reduce the risks. Use the best dog dewormer to kill the infection and prevent spread to other pets in the vicinity!
Roundworms or nematodes are a group of worms with many species including your common earthworm but not all roundworms are parasitic. The ones that are most likely to make a host out of your pet are Toxascaris leonine and Toxocara canis, the latter being able to infect humans.
They are the most common of all parasites to be found in dogs and it’s inevitable that the dog will have a run in with them at some point in their life. Unlike flatworms and as their name suggests they have a rounded shape and have a pale pinkish white coloration.
A dog is first at risk of transmission from inheriting the juvenile forms from their mother at birth. The juvenile worms can become dormant and resist treatments. They can then be reawakened at a certain stage during a dog’s pregnancy to be passed through to the pups or through suckling after they are born. Parasitic roundworms can also enter your dog’s system if they were to, unfortunately, ingest the eggs in the environment that can be found in soil and foliage or through wildlife that is also infected.
Detection and Symptoms
Adult worms can be spotted in your dog’s stools and vomit. The worms can cause upsets with your dog’s digestive system causing them to vomit and also resulting in diarrhea ranging from mild to chronic.
Much like the tapeworms, roundworms also sap the nourishment form the food that is eaten by your dog and in this case, can cause malnourishment, so you’ll notice your dog losing weight despite eating more. If untreated, the worm population can give your dog a potbellied stomach too; it is critical to see a vet if it gets to this point!
The worm can also be quite dangerous if it migrates to the lungs, you’ll see your dog coughing and wheezing if that is the case. In worst case scenarios, pneumonia can occur.
It’s really difficult to prevent roundworm infection by any means other than making sure to clean up after your dog swiftly to reduce the reinsertion of eggs into the environment and the risk of reinfection. Use deworming products to treat and be sure to keep any dead animals out of your yard; do not let your pets go near them!
And against, just like any other parasitic worm, use the best dog dewormer for you and your dog to treat an early infection and prevent the infection spreading to pets in the vicinity.
Hookworms also belong to the family of roundworms but are distinct because they possess hook-like teeth or plates as mouthparts that can be seen under a microscope. The mouthparts are what they use to attach themselves to the wall of the poor dog’s intestines so that they can feed on your dog’s tissues and blood.
The hookworm species found in domestic dogs go by their scientific names Ancylostoma caninum and Ancylostoma braziliense and just like other parasitic worms, their eggs are taken from the environment, the adult form grows within the dog and passes more eggs into the environment through your dog’s feces.
They are also motile and very small and so can make their way into their intended destination by moving, sometimes through the skin. Additionally, they can be transmitted through an infected mother breastfeeding their young and can become doormen during pregnancy much in the same way as parasitic roundworms.
Detection and Symptoms
Loss of appetite and diarrhoea are issues that can arise from this infection as well as blood occurring in the stools in more severe infections. Coughing can be a symptom of the migration of juvenile worms into the lungs which are coughed up and swallowed allowing access to the intestines.
Your dog might show some irritation on the skin around their feet and toes as the worms penetrate the skin and migrate through it. Due to their blood-sucking nature, anemia can also occur and can be fatal in puppies. The severity of symptoms can range between mild and severe depending on your dog’s age, health and the number of worms present.
Since the eggs are present in the environment, there is little you can do as preventative measure other than the best dog dewormer products. Be sure to recognize infection if you have a pregnant female and see your vet or obtain the best dog dewormer to get it treated as soon as possible.
The whipworms found in dogs have one species that we are to be concerned with and that’s Trichuris vulpis. Their eggs can be very resilient and live in the environment for up to a year, giving them good chance to find a host to ingest and contract them.
They’re typically around a quarter of an inch in size and their body gets progressively thinner as you move towards the tail end which is what gives them their name. They make their home in the colon and large intestines.
Detection and Symptoms
An early infection of whipworm can be quite difficult to detect and sometimes your dog will show no symptoms during the early onset. At larger infections with more worms present, bowel inflammation and bloody diarrhea can occur.
You might also notice some weight loss and your pet drinking more water due to dehydration whilst a vet will be able to detect anemia through a blood test.
As with most of the other parasitic worms, the best prevention is keeping their living area clean including their food/drink bowls, toys and bedding. Keep the yard clear of dead animals which are a potential risk of infection and always clean up after your dog so not to infect other animals, pets and to reduce the risk of reinfection.
