Several studies have evaluated whether metronidazole helps with vomiting in dogs. This article explains, does metronidazole helps with vomiting and nausea in dogs or not?. 

The short answer to the question is, No. Metronidazole is an antibiotic drug and is used for the treatment of bacterial and protozoans infections. 

What is Metronidazole Prescribed for in Dogs?

In general, metronidazole is prescribed to treat an infection caused by a bacterial or protozoan parasite. Your veterinarian should diagnose the underlying cause of your pet’s diarrhea before prescribing metronidazole. 

Can Metronidazole Cause Vomiting & Nausea in Dogs?

Despite its benefits, metronidazole is associated with a few side effects. 

For example, it can cause excessive salivation, vomiting, and diarrhea. This medicine also causes nausea and drooling. 

Fortunately, the side effects are typically mild and do not require discontinuation. However, you should consult your vet if your pet experiences any of these side effects. 

It is important to check the dosage of metronidazole and any other medications they may be on to ensure they are safe for your dog.

Some Common Side Effects of Metronidazole in Dogs

Some dogs experienced diarrhea within one to two days after treatment, while others had diarrhea that lasted for five to seven days. 

Several health problems involving the gastrointestinal tract and immune system require antibiotics to resolve, while others may respond to supportive care alone. 

In these studies, metronidazole was given in an open-label fashion, and neither population experienced a relapse of clinical symptoms or death.

Can Metronidazole Cause Neurological Side Effects in Dogs?

One concern with metronidazole for dogs is that it can cause neurological side effects. A dog may exhibit dizziness, weakness or slow eye movements, or experience vomiting after receiving the medication. 

If this happens, you should contact your veterinarian immediately to discuss the side effects. 

If you see any of these symptoms, contact a veterinarian immediately to determine whether you should increase the dose of metronidazole.

Does Metronidazole Require Bloodwork in Dogs?

To determine the cause of the illness, the veterinarian may order blood work and ultrasound.

The physical exam includes a thorough examination of the dog’s weight, height, reflexes, skin and coat condition, heart rate, breathing, oxygen level, and blood pressure. 

Standard tests may also be required, including an MRI and spinal tap. The MRI is used to assess the brain’s health and to check for symptoms of cerebellar degeneration or hemorrhage. 

Anesthesia is needed for this test. Serum analysis, blood count, and x-rays may be necessary to confirm the diagnosis.

Metronidazole Dosage for Dogs

Metronidazole dosage for dogs is specific to the condition they’re treating but generally ranges from 10 to 30 milligrams per kilogram of body weight. 

Duration of the Treatment 

For most dogs, the duration of treatment is around five days, although some animals may require more than a month’s worth of treatment. 

Your vet will prescribe the appropriate dosage for your dog. For best results, consult your veterinarian before administering metronidazole to your dog.

Long-Term Side Effects of Metronidazole in Dogs

While metronidazole can help temporarily suppress diarrhea, it can have serious long-term side effects such as upset stomach, diarrhea, and vomiting. 

To minimize the risks associated with metronidazole, talk to your veterinarian about any dietary changes or routine changes you plan to make for your pet. 

If you find that metronidazole isn’t helping, consider other remedies that may work in conjunction with it.
