These statistics reflect the vulnerability of our canine companions to intestinal parasites. To protect your beloved pets, it’s essential to learn about this disease, which includes the symptoms of parasites in dogs, their treatment options, and more. 

In this blog, we’ve discussed everything about intestinal parasites. You will find all the information you need to keep your dogs safe from this disease, from causes to treatment options. 

So, let’s begin! 

Overview of Intestinal Parasites in Dogs 

Dogs can ingest intestinal parasites or their eggs by taking contaminated food or water. These tiny living organisms start residing in dogs' digestive tracts and feeding on their nutrients, leading to serious health concerns. 

Types and Symptoms of Parasites In Dogs 

There are numerous types of intestinal parasites in dogs; each affects the dog’s digestive system in multiple ways. The most common types include the following: 

1. Roundworms

Roundworms, including Toxocara canis and Toxascaris Leonina, are the most common parasites in dogs. 

Roundworms have long and slender bodies of white or light brown color. They can lead to malnutrition and weight loss in dogs. 

In addition, roundworms are easily transmitted to humans. 

So, taking precautions is important when dealing with a pet patient suffering from this specific intestinal disease. 

2. Tapeworms 

Tapeworms live in the small intestines of dogs and can lead to:

  • Vomiting
  • Diarrhea
  • Weight loss

These small, flatworms can be transmitted when pets eat fleas or other insects. The common types of tapeworms are ​:

  • Dipylidium caninum
  • Taenia species
  • Echinococcus species

3. Hookworms

As the name suggests, these worms have hook-like shapes that typically stick to the lining of the small intestine. 

They can cause weight loss and anemia and can be easily transmitted to human bodies, including their most common types:

  • Ancylostoma caninum
  • Ancylostoma Braziliense

4. Whipworms

However, if not treated on time with effective treatment options, they can lead to serious health concerns like:

  • Diarrhea
  • Bloody stools

This is a microscopic and single-celled parasite that can be ingested when the dog comes in contact with the contaminated feces of infected dogs.

Different Methods to Treat Parasites in Dogs 

The most effective method for treating parasites is deworming (under the supervision of a licensed veterinarian). 

These medications can be in the form of pills or liquids. The medication and length of the course depend on the type of parasite and its severity. Apart from this, maintaining a balanced diet that is rich in nutrients is essential for enhancing gut health. 

Veterinarians recommend adding fiber-rich food to the dog’s diet to prevent parasite growth.
