Is Giardia Common in Puppies?Is Giardia common in puppies? How concerned should you be? Puppies are adorable, but they and their immune systems require a lot of maintenance and care, including keeping an eye out for the giardia parasite. Giardia is a microscopic parasite that can cause watery diarrhea and other unpleasant symptoms in dogs. It can be particularly prevalent in puppies, but many dog owners aren’t sure what to look for or how to prevent it. In this blog post, we’ll take a closer look at giardia and answer the question, “Is giardia common in puppies?”

What is Giardia?

Giardia intestinalis is a single-celled parasite that typically infects the small intestine of dogs. It’s spread through contact with the feces of an infected dog, which can happen in a variety of ways. For example, if you take your puppy to a dog park and they come into contact with contaminated feces, they could become infected with giardia.

Similarly, if you have an infected dog at home and don’t practice good hygiene, like keeping clean water and practicing good personal hygiene, your other dogs may become infected as well. Your dog can also get it from contact with infected wild animals, which is why it is important not to let your pup interact with wild animals while outdoors. Practice caution during outdoor activities such as outdoor play, hiking, and walking. 

Signs of Giardia Infection

The most common symptom of giardia infection is watery, severe diarrhea. However, there are other signs of infection to look out for as well, including loose stool, vomiting, and loss of appetite. Not all dogs exhibit clinical signs of giardia, but if your puppy is exhibiting any of these symptoms, it’s a good idea to collect a stool sample and have them checked out by a veterinarian to have diagnostic tests run.

Remember, diarrhea and vomiting can lead to dehydration which means your pup could be in danger of needing intravenous fluids and other medical intervention if their infection becomes too severe. A good rule of thumb is to be safer than sorry. If your pup is exhibiting any abnormalities, take them to the vet straight away. An infection or issue caught early is better than letting it go for a while. 

Diagnosis and Treatment

If you suspect that your puppy is infected with giardia, your veterinarian will likely want to perform a fecal sample test for the tiny parasite. This involves taking a sample of your dog’s stool and examining it under a microscope for the presence of giardia cysts. If your puppy or one of your senior dogs is diagnosed with giardia infection, your veterinarian may prescribe oral medication to help clear up the infection as well as a dewormer to kill the parasites and any eggs. 

You will also want to perform environmental disinfection, making sure to disinfect all hard surfaces and wash all soft surfaces, like blankets,  your pup’s crate, and bedding, to get rid of any fecal matter that might have leftover giardia organisms in them. You can find soaps and other kinds of cleaning supplies at your local supermarkets and pet stores.

You will also want to make sure your dog has access to fresh water and talk with your doctor about a gentler diet to feed your dog while your dog’s intestines improve from the worst symptoms of giardia. Keeping your pup isolated from other pets in the household is a good option to make sure the parasite is not spread. Having your pet in its own crate or kennel, with its own bedding, dog bowls, and other supplies, is necessary so no cross-contamination can occur. 


Preventing giardia infection is all about good hygiene practices. Make sure to clean up after your dog promptly, especially in areas like dog parks where there may be a higher prevalence of giardia. Wash your hands frequently, especially after handling dog poop or coming into contact with an infected dog. Keep food bowls and water bowls clean and sanitized, and avoid letting your dog drink from stagnant water sources like puddles.

So, is giardia common in puppies? The answer is that it can be, especially if you’re not practicing good hygiene and sanitation practices. However, with a little bit of knowledge and effort, you can help keep your puppy safe from giardia and other parasites. Stay vigilant, keep your dog’s environment clean, and don’t hesitate to consult with your veterinarian if you suspect that your puppy may be infected with giardia. By taking these simple steps, you can help ensure that your furry friend stays healthy and happy for years to come.
