Giardia in Dogs and Cats: What to Know
A Common Parasite That’s Often Mistaken for Other Digestive Issues

Giardia is a microscopic intestinal parasite that can cause diarrhea and digestive upset in pets.
What Is Giardia?
Giardia is a gastro intestinal infection caused by a microscopic parasite called Giardia lamblia. This is a common parasite causing gastrointestinal illness. It is found in the stools of many animals, including rodents, dogs, cats, cattle, and wild animals.
A Giardia infection can be acquired when your pet ingests food or water that has been contaminated with the parasite and then multiplies in the small intestine. The infection can also be spread person-to-person when hands, which are contaminated with an infected person's stool, are brought in contact with the mouth. Swallowing as few as ten parasites can cause the infection.
Common Symptoms of Giardia
- Diarrhea
- Soft, foul-smelling or greasy stools
- Gas and abdominal discomfort
- Weight loss
- Poor nutrient absorption
- Vomiting
- Weakness
- Abdominal cramps
Has your dog or cat had ongoing diarrhea, gas, or unexplained weight loss?
A conversation about your pet is a good place to start.

Getting the Correct Diagnosis
The symptoms of Giardia can resemble food sensitivities, inflammatory bowel disease, colitis, and other digestive disorders. Because of this, proper testing by your veterinarian is important before beginning treatment.
Can Giardia Be Treated Naturally?
Yes, Giardia can be treated naturally. My goal is to support the digestive tract, improve overall intestinal health, and help the body create an environment that is less favorable for the parasite. Every pet is different, so the program should always be tailored to the individual animal.
Why Every Pet Needs an Individualized Plan
There is no one-size-fits-all natural Giardia program. Your pet's age, diet, medical history, digestive health, medications, and overall condition all influence which recommendations are most appropriate.
Schedule a Consultation

Frequently Asked Questions
What is Giardia in dogs and cats?
Giardia is an intestinal infection caused by a microscopic parasite. It's picked up from contaminated food, water, or contact with infected stool, and it's common in dogs, cats, and many other animals.
What are the symptoms of Giardia in pets?
Diarrhea, greasy or foul-smelling stools, gas, abdominal discomfort, weight loss, and poor nutrient absorption are common. Because these symptoms overlap with colitis and irritable bowel syndrome, proper veterinary testing is important before starting treatment.
Is Giardia the same as IBD or colitis in dogs?
No, but the symptoms can look very similar. Giardia is caused by a specific parasite, while IBD and colitis often stem from a mix of diet, stress, and other underlying factors. Getting a correct diagnosis is the first step.
Can Giardia be treated naturally in dogs and cats?
Yes. Natural support focuses on strengthening the digestive tract and creating an environment less hospitable to the parasite. That said, proper veterinary testing and guidance are still important for an accurate diagnosis.
How is Giardia diagnosed in pets?
A veterinarian can confirm Giardia through fecal testing, since its symptoms can mimic other digestive conditions. Once confirmed, a personalized nutrition and supportive care plan can help your pet recover.
