What is Colitis in Dogs? and How to Treat it?

Colitis is the swelling or inflammation of the colon (large intestine). The primary goal of drug therapy is to suppress the immune response. Anti-inflammatory medications are the first line of defense against the disease, and immunosuppressive agents may be prescribed in more severe cases. 

Prednisone or prednisolone are two common medications used as anti-inflammatory agents. 

Both drugs are effective and widely available. Most pets will see an improvement in their condition within two to three weeks after starting the treatment.

However, the study authors cautioned that metronidazole should be used cautiously in dogs, because the drug may upset the microbiome. They also suggested other, non-drug options to treat GI conditions. 

Additionally, the authors recommended testing the health of pets’ guts to ensure that they have a healthy balance of bacteria. Overall, this study has important implications for veterinary care.

Metronidazole affects bacteria by inhibiting the synthesis of DNA. This antibiotic has been used to treat intestinal disease in dogs since the 1960s. 

Although it does not appear to affect a specific group of bacteria, it is effective in decreasing the number of other bacterial strains in dogs. Compared to a placebo, metronidazole reduced the number of Bacteroides and Clostridiales.

Immune System

Sometimes, however, an immune system problem in the colon is the cause of inflammation. If your dog experiences any of these symptoms, your veterinarian may recommend a course of treatment.


Stress is another factor that can trigger colitis. Both physical and psychological stress can cause the symptoms to develop and can affect dogs of any age. In fact, stress is more likely to cause acute colitis, affecting younger animals more than older ones. 

While stress can trigger colitis, it can also lead to inflammation of the colon, which will block its absorption of water. One of the most common symptoms of stress colitis is diarrhea.

How to Diagnose Colitis in Dogs?

Diagnostic testing for colitis in dogs is based on clinical signs and microscopic examination of feces. Your veterinarian will likely ask about the dog’s bowel movements and how long they have been occurring. 

In addition to looking for signs of infection or parasites, he or she may ask about stool appearance, how frequently he or she defecates, and whether your dog appears to be straining to defecate. 

In some cases, a colonoscopy or barium enema is required to confirm the diagnosis.

What Causes Colitis in Dogs?

What causes colitis in dogs and how does metronidazole treat it? Colon inflammation (colitis) in dogs can be caused by several different causes. Some of these causes are bacterial in origin, such as Clostridium

Other causes are more serious, such as parasites. Cats and dogs are more likely to develop colitis than humans are. Cats and dogs have a higher prevalence of this disease than humans, but both have similar symptoms.

Antibiotics for Dogs

Antibiotics are a valuable tool in treating sick pets, but it’s important to use them only if needed. For example, antibiotics kill good bacteria that are essential for digestion and immune system health. 

This imbalanced microbiome can lead to adverse effects. Fortunately, scientists have recently discovered that metronidazole can dramatically alter the composition of the gut microbiome of dogs.

Another study found that metronidazole reduced the overall richness of the gut microbiome in dogs. Despite the fact that the antibiotic has a strong antibacterial effect, the changes in the microbiome did not disappear after four weeks of treatment. 

As a result, metronidazole should be used carefully. For some dogs, it might be necessary to treat diarrhea with other forms of medication.

Antibiotics for Colitis in Dogs

Using antibiotics for inflammatory bowel disease (IBD) and colitis in dogs can have adverse effects on the dog’s gut microbiome. This is because antibiotics kill the good bacteria necessary for digestion. 

In contrast, supportive care is just as effective for hemorrhagic gastroenteritis, which usually responds well to supportive treatment. 

In some cases, metronidazole can worsen diarrhea, as it reduces the population of “good” anaerobic bacteria and alters the intestinal mucus.

What is Stress Colitis in Dogs?

What is stress colitis in dogs and how is it treated? Stress colitis is an inflammation of the colon and large intestine that is often caused by a variety of factors, including sudden dietary changes, parasite infections, and stress. 

Stress negatively affects a dog’s microbiome, a complex mixture of bacteria and other organisms living in the digestive tract. 

Stress can result in an overgrowth of the bad bacteria in the colon and decreased levels of the beneficial bacteria, making the dog more susceptible to infections.

A veterinarian may recommend a prescription for a calming pheromone spray. While your dog is sedated, this medication can be used to help your dog relax. 

It is important to remember that dogs do not metabolize human medications the way humans do, so giving them a prescription for a human medication can be dangerous or counterproductive. 

Your veterinarian will be able to determine the cause of your dog’s colitis, which will allow him to prescribe an appropriate treatment.

What is Allergic Colitis in Dogs?

There are different types of intestinal inflammation, including allergic and inflammatory. The cause of colitis can be food allergies or dietary intolerances. It can also be triggered by parasites or infections, such as bowel cancer. 

Antibiotics often interact poorly with a dog’s digestive tract and kill off beneficial bacteria. To alleviate the symptoms of allergic colitis in dogs, veterinarians may prescribe an antiparasite drug called metronidazole.

This drug is a powerful antibacterial, and also antiprotozoal. It works by preventing organisms from multiplying and creating. Because it can cross the blood-brain barrier, it also works on bacteria in the central nervous system. 

It is also known to help dogs heal faster. It is often prescribed as a single medication for allergic colitis in dogs, but can also be used in combination with other antibiotics to treat other conditions.

While metronidazole can alleviate symptoms of allergic colitis in dogs, it can also have some dangerous side effects. 

Flagyl is an antibacterial drug, but this medication can cause gastrointestinal upset. Some pet parents have trouble medicating their dogs three times a day. 

The most important thing to remember is to follow your veterinarian’s instructions. If you are unsure, ask your vet for a consultation.

The Best Treatment for Colitis in Dogs

When considering the best treatment for colitis in dogs, one of the first questions to ask is: is metronidazole a good option? 

This antibiotic has a narrow spectrum, killing several types of bad bacteria and promoting faster colon healing. It is also a useful treatment for dental infections. If metronidazole is not an option, there are other antibiotics that are.

The best treatment for colitis in dogs with metronidazole is one that involves an oral antibiotic. Known as Flagyl, metronidazole can be effective against many types of parasitic and bacterial infections in dogs. 

This treatment is only available by prescription, and it is an off-label use. Veterinarians often use metronidazole to treat diarrhea in dogs because of its effectiveness against anaerobic bacteria. 

This antibiotic can also be used to treat certain conditions involving the central nervous system, including sepsis and internal abscesses.

Sulfasalazine for Colitis in Dogs

In addition to metronidazole, another common drug is sulfasalazine. It is a synthetic anti-inflammatory drug that inhibits the immune system and is typically used for a limited period of time. 

It is more commonly used in dogs than in cats and is often prescribed in conjunction with antibiotics. This treatment is most effective when it has been used for at least two weeks.

Home Remedies for Colitis in Dogs

While the use of antibiotics is necessary in severe cases, there are many home remedies for metronidazole-treated canine colitis. 

Boiled Chicken or Steamed Brown Rice as a Diet

One of these methods involves changing your dog’s diet to be easier on its tummy. Some veterinarians recommend boiled chicken or steamed brown rice, which are both easy on the tummy and low in fiber. 


In addition, some dogs respond well to a reduction or increase in fiber. Another approach is to give your dog probiotics, which are commercially packaged versions of beneficial bacteria that can help protect the delicate lining of the colon.

Reduce Stress

Other methods for treating colitis in dogs involve reducing stress. Stress can be a trigger of colitis, and you need to learn to recognize the signals that will relax your dog. 

Try to limit stressful situations in your dog’s life as much as possible. Once you identify these triggers, you can begin treating the condition at home. You can even teach your dog to use a stress ball to help calm him down.
