Can Dogs Live with Giardia?


Giardia is a common intestinal parasite found in humans and dogs worldwide. It causes diarrhea and vomiting, but can be easily treated and eliminated from your home. This article will discuss what giardia is, how it affects dogs, and its treatment and prevention.

Signs and Symptoms of Giardia in Dogs

Giardia is a microscopic parasite that attaches to a dog’s intestinal wall, causing foul-smelling diarrhea. Stools may be soft, watery, green, and contain blood or excess mucus. Dogs may also experience vomiting and weight loss due to dehydration. It’s important to note that symptoms can be intermittent or chronic, and while giardia is rarely fatal, it can be life-threatening to animals with weak immune systems.

Body Language

Look for signs of giardia infection in your dog’s body language, such as weakness, dropped ears, sleepiness, and other symptoms like diarrhea, vomiting, lethargy, and gradual weight loss.

The Science of Giardia

Giardia is a single-celled parasite that resides in the intestines of mammals, birds, and amphibians. It has a direct life cycle, with mature parasites multiplying in the small intestine and becoming cysts in feces. These cysts can survive in water or damp areas for months and are ingested by new hosts, repeating the cycle.


Dogs can become infected with giardia by drinking contaminated water, eating contaminated food or feces, licking contaminated fur, or ingesting other contaminated objects. Infected dogs can spread giardia even if they show no symptoms, making treatment of infected animals and their environment crucial to prevent further spread.

Diagnosis and Treatment

If your dog has diarrhea, see a vet for examination and tests to diagnose giardia. Feces examination and stool samples may be used to detect the parasite. The most common drugs used to treat giardia are fenbendazole and metronidazole, given for 3 to 10 days. Supportive treatment to alleviate symptoms and a special diet may also be recommended. Follow-up testing is necessary to ensure successful treatment.


Most dogs recover fully from giardia with proper treatment. However, older dogs and those with weak immune systems are at higher risk of complications, and death can occur. Early vet intervention and good general health increase the chances of a successful recovery.
