In this article, we will answer frequently asked questions about gastritis in dogs. In this article, you can find answers to frequently asked questions about gastritis in dogs, including its causes, symptoms, and treatment.

What is Gastritis in Dogs?

Gastritis is a health problem that occurs due to inflammation of the gastrointestinal lining, or stomach lining, in dogs, and the symptoms of this health problem significantly reduce the quality of life of dogs. This health problem, also defined as inflammation of the stomach lining, is considered as short-term (acute gastritis) or long-term (chronic gastritis). Gastritis can be a health problem on its own or it can occur as a result of other serious health problems.

Causes of Gastritis in Dogs?

When considering the causes of gastritis in dogs, it is necessary to distinguish between acute and chronic gastritis. Acute gastritis is much more common in dogs than chronic gastritis. Dogs, especially those with eating habits or those who are not very obedient, are more likely to develop acute gastritis. Consuming foods or substances that dogs shouldn't eat is the most common cause of acute gastritis. In cases of acute gastritis in dogs, inflammation is usually caused by the ingestion of contaminated, toxic, or easily indigestible substances.

Causes of acute gastritis;

  • Consumption of spoiled, rotten or contaminated food,
  • Consumption of garbage or cat litter,
  • Consumption of plants harmful to dogs' stomachs,
  • Use of medication,
  • Ingestion of foreign objects or non-food substances,
  • Contact with mold or mildew,
  • Contact with products containing chemicals,
  • Infections caused by bacteria, viruses or parasites,
  • Prolonged exposure to allergens Acute gastritis can be caused by:
  • Immune diseases,
  • Stomach cancer,
  • Kidney failure,
  • Inflammatory bowel disease,
  • Neurological diseases,
  • Ulcers,
  • Heavy metal poisoning,
  • Chemotherapy. Acute gastritis is a health problem where the cause must be determined and a treatment plan developed accordingly. Although it is commonly related to the consumption of incorrect food or foreign objects, it is very important to ensure that a more serious underlying disease is not the cause of acute gastritis.

Chronic gastritis in dogs is caused by persistent inflammation of the stomach. The reasons for persistent stomach inflammation include:

  • Improper nutrition,
  • Continuous exposure to toxic substances,
  • Regular use of medications with side effects,
  • Metabolic or endocrine diseases,
  • Enfeksiyonlar olarak ifade edilebilir.

Symptoms of Gastritis in Dogs

Gastritis, which occurs when the gastrointestinal lining, or stomach lining, in dogs becomes inflamed, can cause symptoms on its own or lead to other problems such as ulcers, gastrointestinal obstruction, or infection. Therefore, the symptoms of gastritis in dogs do not necessarily have to be only symptoms directly related to the stomach and digestive system, such as diarrhea and vomiting. Symptoms of acute gastritis can include:

  • Vomiting containing yellow and frothy bile,
  • Decreased appetite,
  • Diarrhea,
  • Weakness and lethargy,
  • Depression,
  • Dehydration or increased thirst,
  • Blood in stool or vomit,
  • Abdominal pain,
  • Black tar-like appearance in stool. Symptoms of acute gastritis usually disappear within 24 hours. Therefore, it can be difficult to diagnose. In chronic gastritis, symptoms last longer. Chronic gastritis typically lasts two or more weeks, and symptoms worsen over time.

Symptoms of gastritis in dogs must be taken seriously, and a veterinarian should be consulted if noticed. Acute gastritis symptoms can easily be overlooked as they disappear quickly, but if any of the symptoms are encountered more than once, a veterinarian should be consulted due to the possibility of gastritis.

Treatment of gastritis in dogs

How is Gastritis Diagnosed in Dogs?

Urine and blood tests are generally used to diagnose gastritis in dogs. Urine and blood tests are helpful in diagnosing acute cases. In some cases, a more comprehensive examination may be necessary. Endoscopy, abdominal X-ray, or abdominal ultrasound are also among the methods used to diagnose gastritis in dogs. When it comes to chronic gastritis in dogs, the underlying cause must be found.

Treatment of Gastritis in Dogs

Two different approaches are considered in the treatment of gastritis in dogs. In acute gastritis cases in dogs, improvement usually occurs without any medical intervention. When acute gastritis begins to recur frequently, more detailed treatment plans are required.

Treatment planning for acute gastritis in dogs generally focuses on relieving stomach discomfort. Keeping the dog away from food for 24-48 hours. Ensuring frequent but small amounts of water consumption in the first 24 hours is important. If the dog starts vomiting after drinking water, a veterinarian should be consulted again and a different treatment plan should be implemented. If no vomiting occurs within 24 hours of starting this non-medical treatment process, it is appropriate to start consuming small portions of highly digestible foods recommended by the veterinarian. Feeding can begin by dividing half of the dog's daily food intake into 4 to 6 portions. After starting this feeding, the normal food amount can be gradually increased within approximately 3 days. If vomiting recurs during this period, a veterinarian should be consulted.

In the treatment of gastritis in dogs, medication may be necessary if deemed appropriate. Additionally, fluid therapy may be necessary depending on the dog's dehydration. Chronic gastritis in dogs requires treatment of the underlying cause.

What is Good for Gastritis in Dogs?

After treating gastritis in dogs, various precautions may be necessary. Choosing food suitable for the dog's health condition is important to prevent recurrence. Furthermore, the dog should not be allowed to eat whatever it wants. If a dog tends to rummage through garbage or eat food it finds outside when left alone, it should not be allowed to roam freely or unsupervised. Keeping the dog away from foods that irritate its stomach is also among the precautions that can be taken for gastritis. Feeding the dog with food suitable for its health problem and continuing this feeding for at least 3 weeks, ideally 6-8 weeks, helps prevent diet-related gastritis and makes it easier to adjust the dog's diet. After any food change, sufficient time should pass to determine whether the food is suitable for the dog. Washing Dogs with Human Shampoo Is Dog Skin Sensitive? Dogs need to be washed.
