One serious health issue inducing gastrointestinal upset and discomfort is giardiasis in dogs. Known scientifically as a single-celled parasite called Giardia duodenalis, it can invade not only our canine pal but other animals and, in fact, human beings.
Hence, it matters for every dog owner to know how giardia is transmitted, how it manifests itself, and what treatments and prevention are needed.
This article discusses Giardia in dogs in depth, from its life cycle to mode of transmission, clinical signs, diagnosis, treatment, and prevention.
What Is Giardia?
Giardia is a protozoan microscopic parasite that lives inside many animals’ intestines, such as dogs, cats, and humans. It goes through two phases, specifically the trophozoite, which represents the active feeding phase, and the cyst, a resistant phase, therefore shed with feces.
Such cysts are particularly sinister because they can survive for quite long periods in an environment and infect other animals, including humans.
Life Cycle of Giardia
The Giardia life cycle involves the following stages:
The dog is infected by consuming Giardia cysts through contaminated water, food, or surfaces. It can do this by drinking from puddles, eating food with the organism, or sniffing ground that contains feces.
Intestinal Transformation: When the cysts enter the dog’s intestine, they transform into trophozoites. They attach to the wall of the intestine and multiply.
The Development and Expulsion of Cysts: Some trophozoites transform into cysts after some multiplication time. These may then be shed within the dog’s feces. Some can infect the environment as a new source of infections.
It is also very resistant and can potentially live for months in a moist environment, becoming a long-term threat in areas where dogs tend to visit.
How Do Dogs Become Infected?
There are various ways in which Giardia in Dogs can infect dogs.
Infected Water: The canine becomes infected with the parasite by ingesting Giardia cysts when it consumes contaminated puddles, stream water, or shared bowls.
Fecal Contamination: Dogs catch cysts by snuffling or ingesting feces from an infected animal. This occurs in parks or areas where many dogs congregate.
Environmental Exposure: Giardia cysts survive outside by living in the soil and on surfaces, so humans can pick the parasite up in contaminated ground by walking and then licking their paws.
Self-reinfection: The dogs can again be self-infected when they lick their paws and fur, to which ingested cysts are attached.
Symptoms of Giardia in Dogs
Not all Giardia-infected dogs show signs of disease. But if they do, they may be:
Diarrhea In the majority of patients, it ranges from loose stools to watery diarrhea. Diarrhea may be intermittent in some patients.
Weight Loss: Malabsorption will cause the puppy to lose or not gain weight.
Vomiting: In some cases, dogs can vomit, which causes dehydration.
Chronic diarrhea causes severe dehydration, especially in puppies and the elderly; it is hazardous.
It would go dull or even unhealthy if its nutritional conditions were compromised due to some infection.
The dogs may start manifesting signs of discomfort or stress, whining, or refusing to be touched near the abdomen.
If you notice any of the above signs in your dog, you must visit your veterinarian for a proper diagnosis and an appropriate treatment schedule.
Diagnosing Giardia In Dogs
Diagnosing Giardia in dogs usually involves a combination of veterinary exams and laboratory tests. Your veterinarian may do the following:
Stool Examination: A stool sample is examined for Giardia cysts or trophozoites. Test repetition is sometimes required since cyst shedding may be intermittent.
Antigen Tests: More sensitive tests look for specific Giardia proteins in stool, which may provide a more accurate diagnosis.
More modern, it can detect giardiasis in stool samples through PCR testing. Again, this is very sensitive, but not all animal-related practice has this.
Clinical Signs and History: The veterinarian will use the signs that show on your dog and their history for a proper diagnosis.
Treatment of Giardia In Dogs
If the vet tested the pet positive for Giardia in Dogs, then the best-prescribed medication from a vet should be followed. Treatment methods most used include:
Antiparasitic Medications: The most common medications your veterinarian will prescribe to remove this Giardia parasite from your dog’s system are fenbendazole (Panacur) and metronidazole (Flagyl). These are often provided for several days, while in other cases, your veterinarian may use both since they can be given in combination to treat more extreme infections.
Supportive Care: It is essential to keep your dog hydrated, especially during diarrhea. Your veterinarian may prescribe electrolyte solutions or special diets to reestablish balance. They can also recommend feeding a low-residue, highly digestible diet to reduce loose stools while the pet is under treatment.
Reexposure fecal: After his treatment regimen, he should examine your animal again to ensure it has wiped out Giardia. It must be said that even if the patient is successfully treated with an infection, giardia is ubiquitous post-infectious. Still, antigens can keep his tests positive when he’s over the infection.
Bathe: At the end of treatment, Bathe removes the remaining Giardia cysts from the dog’s hair coat to avoid reinfection.
Preventing Giardia In Dogs
Prevention of Giardia in dogs: The following preventive measures have proven to reduce the chances of infection significantly:
Fresh Water: Provide fresh water for your dog to drink in an elevated feeding bowl to minimize contamination by feces and soil. If you are in a Giardia-endemic area, you may also want to use a filter that removes cysts or boil the water before it is presented to your dog.
Hygiene Practice: Clean the dog’s living place constantly and remove feces to reduce environmental contamination by your dogs. This is done by picking up after your dog in your compound and in public.
Avoid Infected Areas: Refrain from allowing your puppy to enter places where many other dogs pee, such as parks or petting areas. If a puppy has visited such an area, be attentive enough to know when to be on guard.
Regular Veterinary Check-Ups: Regular vet visits may help identify infections early and thus keep your dog healthy. Discuss Giardia or any other parasite you might be worried about with your vet with your vet.
Limit Self-Grooming: If your dog has been in a possibly contaminated area, try to limit them from self-grooming until you can bathe them to keep them from ingesting cysts.
Educate yourself and others: Knowing Giardia and its transmission can empower you to take the proper precautions for your dog and educate other pet owners.
Is giardiasis contagious to humans?
It has mainly infected dogs; however, a human can still get the infection. There is also a low possibility of passing the infection from dogs to humans. A human person usually gets the infection by consuming contaminated water or food and not by direct contact with the infected pet. To reduce risks, maintain proper hygiene, such as washing hands after contacting your dog or cleaning feces.
Zoonotic Potential
There is more than one genotype of Giardia. Although some strains could be transmitted by humans and dogs alike, familiar strains of Giardia strains typically infecting dogs do not have the identical common strains of Giardia found in humans. In other words, obtaining Giardia from a dog is possible, but it’s relatively rare.
Still, proper hygiene should always be maintained, especially by those whose immune systems are composed—for example, chemotherapy patients or those with something such as HIV/AIDS.
Conclusion: Giardia in Dogs
The disease in dogs, named giardiasis, is one of the most significant health conditions that can cause gastrointestinal illness if not promptly treated. Knowing how the parasite spreads, its symptoms, and available treatments can prepare you better in case your dog gets infected by this nasty parasite.
Prevention and hygiene are the best defenses against it. If you suspect your dog to be infected, go for guidance and support from your veterinarian. The knowledge and care of that dog would lead to having a healthy, happy furry friend.
