Giardia in Pets
A Common Parasite That Deserves Quick Action
Giardia is one of the most common causes of diarrhoea in both cats and dogs — especially in warm, humid climates like the UAE. It’s a microscopic parasite that affects the intestines, often spreading through contaminated water, soil, or faeces.
While many cases are mild, Giardia can cause persistent digestive upset if left untreated. It’s also highly contagious among pets, which means early diagnosis and proper hygiene are key to stopping it in its tracks.
Whether you’re concerned about symptoms, seeking a diagnosis, or trying to prevent reinfection in a multi-pet household, our team is here to help — with fast testing, expert treatment, and clear advice.
What Is Giardia?
Giardia is a single-celled organism that lives in the intestines and interferes with your pet’s ability to absorb nutrients properly. Pets become infected by swallowing the parasite’s cyst form, which is shed in faeces and can survive in the environment for weeks.
Your pet might pick it up from drinking puddles, sniffing or licking contaminated surfaces, or even from grooming themselves after exposure in shared spaces like parks, kennels, or litter trays.
Although some pets show no symptoms, others experience ongoing discomfort that may seem to improve — then flare up again. Left untreated, Giardia can lead to dehydration, weight loss, and nutrient deficiencies, particularly in puppies, kittens, or pets with weakened immune systems.
Recognising the Signs
Symptoms of Giardia can be easy to miss at first. They often overlap with other causes of stomach upset — but tend to linger, come and go, or affect more than one pet in the home.
Watch out for:
-
Soft, foul-smelling stools or persistent diarrhoea
-
Mucus in the faeces
-
Reduced appetite or energy
-
Bloating or gurgling sounds in the belly
-
Weight loss despite normal eating
-
Vomiting (more common in cats)
If your pet seems out of sorts or their digestive issues keep returning, it’s worth booking an appointment — especially if you have more than one animal at home.
Diagnosis and Treatment
Diagnosing Giardia typically involves a combination of faecal tests — some of which can be run in-house for same-day results. Because Giardia cysts aren’t always shed consistently, we may recommend submitting more than one sample to confirm the diagnosis.
Treatment is straightforward. We’ll prescribe a course of antiparasitic medication, which may be combined with probiotics or dietary changes depending on your pet’s symptoms. Most pets respond well within just a few days, and a full course of treatment usually lasts 5–10 days.
Preventing Reinfection
Giardia can be stubborn — and reinfection is common if environmental hygiene isn’t addressed at the same time as treatment. Cysts can stick to fur, carpets, toys, and surfaces, so we’ll guide you through a cleaning routine to break the cycle.
This may include bathing your pet after treatment begins, washing bedding in hot water, and using a disinfectant that targets parasites. In multi-pet households, we may recommend treating all animals at once, even if they’re not all showing signs.
FAQs
In rare cases, yes — especially in people with compromised immune systems. Good hygiene (handwashing, cleaning up faeces promptly) greatly reduces the risk.
Yes. The parasite can be brought in on shoes, other animals, or through shared bowls or grooming tools.
If symptoms persist, or in cases where there’s a high risk of spreading it to other pets, we may recommend retesting to ensure the infection has cleared.
Some pets may recover without treatment, but symptoms often linger or return. Treatment ensures your pet is comfortable and helps prevent transmission to others.
