Simply put, Metronidazole is a highly valued antibiotic with proven antibacterial and antiprotozoal properties.
When to Use Metronidazole for Dogs?
Commonly known by the brand name Flagyl (Metrogel, Protostat), Metronidazole works to restrict the growth and replication of microorganisms. This helps reduce the effect these organisms have on the dog, providing quick relief from the pain and discomfort.
Metronidazole is a versatile antibiotic that can be used for different diseases and health issues in dogs. However, if you are not sure whether this is the right choice for your dog, talk to your trusted vet.
Like the rest of the nitroimidazole derivatives, Metronidazole is effective against some protozoa, anaerobic bacteria, and certain parasites. It is a commonly used anti-diarrheal to treat inflammation of the large intestine.
Another large contribution to the popularity of Flagyl is the ability to treat Giardia in dogs and cats. Giardia is caused by a protozoan parasite that destroys intestinal cells. This leads to diarrhea, loss of appetite, vomiting, abdominal pain, and fever.
Metronidazole can penetrate bone and teeth. So, for the likes of periodontal disease and oral infection, metronidazole therapy is adequate treatment. Other general bacterial infections causing diarrhea or sepsis are typically treatable with a Metronidazole injection.

Benefits and Uses of Metronidazole for Dogs
Metronidazole for dogs directly affects the DNA of the microorganism. To be more precise, it penetrates the organism and destroys the DNA. It is effective against certain protozoal infections, as well as anaerobic bacterial infections.
These include the likes of Giardia, Trichomonas, and Balantidium coli, all very capable of causing inflammatory bowel disease. The anti-inflammatory effect it has in the gastrointestinal tract is thought to be due to the ability to cause immunosuppression.
The immunosuppression seen with Flagyl is only a small part, so not enough to make the animal vulnerable to secondary infection. This is particularly important as with most medicines, immunosuppression is considered to be a severe side effect.
Metronidazole can also cross the blood-brain barrier. So, unlike a lot of antibiotics, Metronidazole can have an effect on anaerobic bacteria invading the central nervous system. So conditions such as peripheral neuropathy in dogs, and bacterial infections in the brain, can receive reliable medication.
Last but not least, Flagyl can also penetrate bone. Once again, there are not many antibiotics capable of doing this. The ability to penetrate bones means dental complications and bone infections can be managed with this simple yet potent antibiotic option.
Potential Side Effects and Risks of Metronidazole for Dogs
Same as any other drug, Metronidazole can cause side effects in dogs. The most common side effects include nausea, vomiting, and diarrhea. Drooling, blood in the urine and appetite loss are also possible but not as common. If these side effects appear, the vet will prescribe medications for their management.
Plus, the ability of Metronidazole to cross the blood-brain barrier means there is a higher chance of neurological side effects. They can range from mild depression, head tilts, and loss of balance to seizures, lack of coordination, and paralysis in all four legs.
Though paralysis of the legs in dogs is rare, because of the severity, it is definitely worth mentioning. Slight depression and stiffness are also quite common when using Flagyl, however, they are not something to be particularly worried about.
In rare instances, Metronidazole use has been shown to cause pancreatitis in dogs. Prolonged use of this antibiotic can lead to the development of acute pancreatitis (and sometimes chronic pancreatitis) in dogs, which can have a domino effect on further gut health.
Finally, we should note that some dogs can be allergic to this antibiotic. Most allergic reactions manifest with hives and rashes. however, in more severe cases, they can trigger swelling of the airways and cause difficulty breathing. This form of allergic reaction is called anaphylactic shock and is considered a medical emergency.
Metronidazole Dosage for Dogs
When using Metronidazole, it is vital to get the right dose. Dogs usually need between 5-20 mg per kg of body weight. Luckily, the Metronidazole tablets are easy to break, thus allowing precise dosing.
When prescribing Metronidazole, veterinarians warn about the consequences of overdoses. Metronidazole toxicity is possible and usually manifests with vomiting, nausea, and dizziness. In more severe cases, there can be neurological symptoms as well. A dog overdosed on Metronidazole requires urgent veterinary attention.
Since Metronidazole has a repelling, bitter taste, it is not advisable to crush the tablet and mix it with the dog’s food. Instead, it would be best if you used a pill pocket or put the tablet directly into your dog’s mouth, at the base of the tongue.
Keep in mind that Metronidazole starts working 1 to 2 hours after administration. Because of its short-acting nature, its effects wear off within the following 24 hours.
Metronidazole for Dogs Usage Guidelines
Just to be on the safe side and decrease the risk for unwanted side effects, Metronidazole should not be used in young puppies, pregnant, and nursing dogs.
The antibiotic should also be avoided in dogs with debilitated overall health, for example, dogs with advanced kidney disease. The same applies to dogs with seizure disorders and severe neutropenia (low white blood cell numbers).
Metronidazole must be used with extra caution in dogs with liver diseases and dogs that have recently suffered from anticoagulant poisoning.
While on the topic, we should emphasize the fact that drug interactions are possible when using Metronidazole. The antibiotic interacts with many medications, including gastro-protectants (cimetidine), blood thinners (warfarin), phenobarbital, phenytoin, cyclosporine, and certain chemotherapy drugs.
When using Metronidazole or any other antibiotic, it is advisable to use probiotics. This is because prolonged antibiotic usage disrupts the gut’s microbiome and leads to imbalances. Probiotic supplements will ensure the microbiome stays in balance. Luckily, the modern market offers an array of probiotic products formulated specifically for dogs.
