Help, my dog or cat has Giardia!
Does your dog or cat have stomach and intestinal issues such as (recurring) diarrhea, vomiting, and loss of appetite? Then your pet may have contracted a contagious Giardia infection. Giardia is one of the most common gastrointestinal parasites in dogs and cats and is especially found in young animals and those with weakened immune systems. In the blog below, you can read more about what Giardia exactly is, what the symptoms are, and how to best treat Giardia.

What is Giardia?
Giardia is a single-celled parasite that can be found in the intestines of both animals and humans. This means that Giardia is a zoonosis: the parasite can be transmitted from animals to humans. A Giardia infection is highly contagious and therefore spreads quickly in places where multiple animals are present, such as dog parks, kennels, or animal shelters. Young animals, small children, and animals or people with weakened immune systems are at greater risk of infection.
How is Giardia spread?
A Giardia infection always occurs through the mouth. This can happen when your pet comes into contact with contaminated feces, but infection can also occur if the dog or cat licks its paws or fur after a walk outside, drinks or swims in contaminated water, or eats and drinks from a contaminated food or water bowl. The parasite attaches itself to the intestinal wall, where it divides. This causes Giardia to multiply rapidly. A major disadvantage is that Giardia can survive for a long time outside the body of a human or animal, making (re)infection always a risk.
What are the symptoms of Giardia?
The most common symptoms associated with a Giardia infection are stomach and intestinal complaints, such as (recurring) diarrhea, nausea, and vomiting. Symptoms begin about 6 to 14 days after infection. In dogs, the stool often smells very bad and is also slimy and pale. Cats usually suffer from large bowel diarrhea, which means they will defecate more frequently and strain while doing so. The stool can also be slimy and may even contain blood. Both dogs and cats can experience a reduced appetite, and with prolonged diarrhea, the animals can also lose weight.
However, symptoms can also occur to a lesser extent. It is even common for adult dogs and cats to show no symptoms at all but still be infected. If a Giardia infection is not treated, the symptoms can persist for months.
How do you treat Giardia?
Do you suspect that your pet has contracted a Giardia infection? Then contact a veterinarian. To diagnose a parasite infection, a stool test is performed. The veterinarian needs your pet's stool from three days for this. If the test shows that your pet indeed has a Giardia infection, it is important to treat the animal to prevent other animals from becoming infected. Giardia can be treated in two ways: with a deworming medication (containing the active ingredient fenbendazole, which is found in Panacur, for example) or with an antibiotic course (containing the active ingredient metronidazole, which is found in Metrobac or Metrazol, for example). In addition, it is advised to thoroughly clean both the animal and the environment in which the animal lives, because Giardia can survive outside the animal for a long time.
What can a dog or cat eat when they have diarrhea?
It is often advised to give pets with (persistent) diarrhea cooked rice with chicken because it is said to be easily digestible and gives the dog's or cat's intestines a chance to rest. Actually, this is a strange approach. The gastrointestinal tract of a dog or cat needs 6 to 8 weeks to get used to new food, so why would you completely change your pet's diet when your dog's or cat's intestines are already upset?
Besides the fact that the animal needs time to get used to new food, a dog or cat's body can also do very little with rice. Dogs and cats are not able to digest large amounts of rice, and rice also contains little nutritional value.
But what can you give a dog or cat with diarrhea? Choose easily digestible food with high-quality nutrients, but do not suddenly switch food types. Does your pet normally get fresh meat or wet food? Then choose meat with an easily digestible protein source, such as turkey, venison, or (white) fish. If your dog's or cat's daily menu consists of kibble, it is advised to divide the amount of kibble into smaller portions and feed the pet spread throughout the day (for example, every 2 to 3 hours). It is also recommended to skip giving snacks and other extras for a while. It is also important that the animal keeps drinking well because diarrhea can cause dehydration.
The Mono Protein canned foods for dogs from Riverwood contain 70% meat from only one protein source and are available in eight different varieties, including some easily digestible options. View here the complete range of wet food for dogs.
Hygiene and regular deworming are essential
Although you unfortunately cannot prevent a Giardia infection, you can try to minimize the chance of infection. Good hygiene is extremely important here. Below are some tips:
- Remove your cat's feces from the litter box daily and always clean up your dog's feces during walks;
- Keep your pet's food and water bowls clean;
- Regularly clean the beds where your dog or cat often lies, and if you travel with your pet, also regularly clean the car;
- Do not leave your dog or cat's food out and make sure to store the food supply neatly in a sealed food container so flies do not have the chance to transmit the parasite;
- Because the risk of a Giardia infection is higher in young animals and animals with a weakened immune system, it is advisable to avoid places where feces remain on the ground.
Finally, regular deworming of your pet is essential. Prevention is better than cure!
