Giardia in dogs often causes sudden, foul-smelling, greasy diarrhea with mucus, but many dogs, especially adults, show no symptoms while still shedding the parasite. Other signs can include vomiting, weight loss, lethargy, gas, dehydration, abdominal pain, poor coat, and reduced appetite, with puppies being more vulnerable. Diagnosis requires a vet to examine stool samples, looking for the microscopic cysts or specific proteins.
Appearance – Differing from typical diarrhea, poop from dogs with Giardia may appear greasy or shiny and may look to have a slick film on its surface. This appearance occurs due to the infection impacting a dog's ability to absorb fat.
These cysts are acquired from fecal-contaminated water, food, or inanimate objects. Dog strains of Giardia are not known to infect cats, and cat strains are not known to infect dogs. In most cases the infection goes away on its own. But if diarrhea is severe or becomes chronic, then medical attention is required.
Giardia are sometimes confused with worms because they invade the gastrointestinal tract and can cause diarrhea. They are not worms; instead, they are one-celled parasites classified as protozoa. Most pets that are infected with Giardia do not have diarrhea or any other signs of illness.
Fenbendazole is a common deworming medication used to treat Giardia. Another treatment option is an antibiotic called metronidazole. Your veterinarian may also use the two medications in combination.
A bland diet typically includes foods such as boiled chicken, cooked rice, and plain pumpkin. When implementing a bland diet for Giardia treatment, it is important to avoid foods that could further irritate the digestive system, such as fatty or spicy foods.
Pathophysiology
Unlike parvo, Giardia is a parasitic infection that, while uncomfortable and potentially serious, typically responds well to treatment when caught early. Also, dogs with other GI parasites or illnesses (such as a chronic enteropathy) can have more severe clinical signs.
AYRADIA oral suspension is indicated for the treatment of Giardia duodenalis infection in dogs. GIARDIA IS A PROTOZOAL PARASITE THAT: May be present in nonclinical healthy dogs. Presents clinically as gastrointestinal infections commonly causing diarrhea that may be severe in some cases.
Cleaning and disinfecting can help remove Giardia germs from a space where a person or pet was recently sick. Reduce the chances of getting sick, or your pet getting sick again, by cleaning and disinfecting surfaces and items. Always follow the directions on cleaning and disinfection product labels.
Giardia can be anywhere—in the soil, running through creeks, and lurking on your pet's favorite toy. The parasite can practically live forever in contaminated water sources like puddles, ponds, and streams.
Untreated Giardia infections can be serious
Diarrhea can lead to dehydration (loss of fluids) or other serious problems if your pet is not treated by a veterinarian.
Giardia can also be spread easily between pets living in the same household. If you have one dog who becomes infected, chances are good your other dogs will quickly pick up this parasite as well. It can be spread through licking, playing, sharing food bowls, sharing water, and even just walking in the same areas.
The green colour of poo, if someone has a gut infection, is usually caused by the bacteria salmonella, a parasite called giardia, or a virus called norovirus. Most gut infections do improve in five to ten days with self-care.
Once swallowed, coccidia damage the lining of the intestines and interfere with absorption of nutrients. Infected animals may have loss of appetite, abdominal pain, diarrhea (which may contain blood), dehydration, and weakness. However, these signs don't always occur, and some infected animals may seem healthy.
You may be wondering, 'Can I get Giardia from my dog licking me?' and while the risk is quite low, it is still possible and so the proper precautions should be taken. One of the easiest ways to do this is by washing your hands after you've handled your dog's poop, even if you weren't directly touching it.
A: No medication specifically labeled for giardiasis treatment is available, but a deworming and antibiotic combination is generally effective. Probiotics and a prescription diet that support GI health are also beneficial in managing your dog's diarrhea until the parasite is eradicated.
How is giardiasis treated? The most common drugs used to kill Giardia are fenbendazole (Panacur®) and metronidazole. These drugs are usually given for three to ten days to treat giardiasis. Both drugs may be given in combination if necessary.
How did my pet get Giardia? The only known route of infection of Giardia is oral ingestion; this means your pet has ingested the microscopic organism from infected feces, soil, or water. Examples of possible ingestion could include: Direct contact with infected feces from another animal.
Lethargy. Loss of appetite. Vomiting. Severe, often bloody, diarrhea.
Cryptosporidium and Giardia infections cause similar symptoms. You may have some or all of the following symptoms. Cryptosporidium infection symptoms appear 1 to 12 days (usually 7 days) after becoming infected. Symptoms can last for 2 weeks or more.
Your veterinarian will need a fresh stool sample from your dog to test for giardia. The process involves examining the sample under a microscope or using a more advanced ELISA test, which detects giardia antigens in the stool.
People exposed to Giardia may experience mild or severe diarrhea (loose stool/poop), gas, stomach cramps, nausea (a feeling of upset in the stomach), or dehydration (loss of water in the body causing weakness of dizziness). Some people experience no symptoms at all.
This is a common route of infection for travellers and people hiking or camping in the wilderness. There are up to 600,000 cases of giardiasis in Australia each year, and more than 280 million cases worldwide.
But giardiasis doesn't always go away in everyone. And in some people, it can be very persistent. If you continue to have symptoms for longer than six weeks, visit your healthcare provider. They can test you to find out if you're still infected, or if your symptoms are due to the after-effects of the infection.
