What is Giardia?
Giardia is a microscopic parasite that infects the intestines. Dogs (and other animals, including humans) can become infected by ingesting the parasite’s cysts, which are found in contaminated:
Water (puddles, lakes, shared bowls)
Soil
F***s
Surfaces or objects (like paws, toys, or shared areas)
Symptoms in Dogs:
Some dogs show no symptoms, but those who do may experience:
Soft or watery diarrhea (sometimes with mucus or a strong smell)
Gas or bloating
Weight loss
Dehydration
Lethargy
Puppies and immunocompromised dogs are at higher risk of more severe illness.
How Does It Spread?
Giardia spreads through the fecal-oral route, meaning dogs get infected when they lick or ingest anything contaminated with infected p**p — including their own paws after walking in it.
Cysts can survive in the environment for weeks, especially in moist areas.
How to Prevent the Spread of Giardia:
For Dog Owners:
Clean up p**p immediately — even in your own yard
Avoid letting dogs drink from puddles, ponds, or communal water bowls
Wipe paws and rear after walks, especially if diarrhea is present
Wash bedding, bowls, and toys frequently with hot water and disinfectant
Bathe your dog if they’ve had diarrhea or may have rolled in something questionable
Cleaning
Use disinfectants effective against Giardia (not all cleaners work — bleach is best for hard surfaces)
Sanitize shared areas daily, including floors, crates, leashes, and water bowls
Separate infected dogs during treatment and for a few days after symptoms resolve
Limit dog-to-dog contact in outbreak situations
Require owners to keep dogs home if they have diarrhea or have been recently diagnosed
Treatment:
Giardia is typically treated with prescription meds like metronidazole or fenbendazole
Most dogs recover well, but retesting is often needed to confirm it’s gone
Dogs can still shed cysts after symptoms stop, so hygiene is key
Quick Takeaway:
Giardia spreads fast, but it’s manageable with awareness, cleanliness, and quick action.
At Pawsitive Canine Academy, maintaining a clean, safe environment is a top priority — and we work with owners to stop the spread if any pup gets sick.
