Stomach Bugs in Dogs

If you've ever noticed your dog acting a bit off, experiencing vomiting, diarrhea, or refusing to eat, you may wonder if your dog has a "stomach bug." Just like humans, dogs can suffer from gastrointestinal (GI) problems, including what’s commonly referred to as a “stomach bug.” But what exactly causes these stomach issues in dogs, and how can you help your pet feel better?

In this article, we will discuss whether dogs get stomach bugs, common causes of stomach upset, symptoms to watch for, and how to treat and prevent gastrointestinal problems in dogs. Understanding your dog's digestive health is key to ensuring their well-being and comfort.

What is a Stomach Bug in Dogs?

A "stomach bug" in dogs is not a specific medical term but is often used by pet owners to describe a variety of gastrointestinal illnesses that result in symptoms like vomiting, diarrhea, and abdominal discomfort. Stomach bugs can be caused by viruses, bacteria, parasites, or dietary issues. While dogs don’t get “stomach bugs” in the same way humans do (e.g., viral infections like the flu), they can experience similar symptoms due to infections or other gastrointestinal problems.

What Causes Stomach Virus Infection in Dogs?

There are several potential causes of stomach bugs or gastrointestinal upset in dogs. These can be broadly categorized into infectious causes, dietary causes, and other health conditions.

1. Infectious Causes

• Viral Infections: Dogs can suffer from viral infections that affect the digestive system, such as Canine Parvovirus or Canine Coronavirus. These viruses can cause severe vomiting, diarrhea, and dehydration. Though less common than bacterial infections, viral infections require immediate veterinary attention.

• Bacterial Infections: Bacteria such as Salmonella, Campylobacter, and Escherichia coli (E. coli) can cause GI upset in dogs. These bacteria are often transmitted through contaminated food or water, and they can result in vomiting, diarrhea, and abdominal pain.

• Parasites: Giardia, roundworms, hookworms, and other intestinal parasites are common causes of stomach problems in dogs. Parasites can cause diarrhea, bloating, and vomiting. Puppies, in particular, are more vulnerable to parasitic infections, but adult dogs can also be affected.

2. Dietary Causes

• Dietary Indiscretion: Dogs are known for eating things they shouldn’t, whether it’s garbage, spoiled food, or table scraps. Eating something that doesn’t agree with them can lead to vomiting, diarrhea, or stomach discomfort. This is commonly known as “garbage gut” or dietary indiscretion.

• Food Allergies and Intolerances: Some dogs may have sensitivities or allergies to certain ingredients in their food, such as beef, chicken, wheat, or dairy. These food allergies or intolerances can result in GI symptoms like bloating, diarrhea, and stomach cramping.

• Sudden Dietary Changes: If you change your dog’s food abruptly, it can upset their digestive system. It’s important to gradually transition your dog to new food to avoid gastrointestinal issues.

3. Health Conditions and Other Causes

• Pancreatitis: This is inflammation of the pancreas, often caused by a high-fat diet or eating rich table scraps. Symptoms of pancreatitis include vomiting, diarrhea, and abdominal pain. In severe cases, pancreatitis can be life-threatening.

• Gastritis: Gastritis is the inflammation of the stomach lining and can be caused by many factors, including infections, toxins, or stress. It can cause symptoms like vomiting, loss of appetite, and abdominal discomfort.

• Foreign Objects: Dogs are known to chew and swallow items they shouldn’t, such as toys, bones, or clothing. A foreign object stuck in the digestive tract can cause discomfort, vomiting, and in severe cases, a blockage that requires surgical intervention.

• Stress: Just like humans, dogs can experience stomach upset due to stress or anxiety. Changes in the environment, travel, or separation anxiety can cause GI issues in dogs.

Symptoms of Stomach Bugs in Dogs

• Vomiting: Dogs may vomit frequently, especially after eating or on an empty stomach. Vomit may contain undigested food, gastric juices or bile.
• Diarrhoea: The dog may have diarrhoea and the faeces may appear watery, pasty or with mucus and blood.
• Loss of appetite: The dog may show a diminished interest in food or even refuse to eat altogether.
• Weight loss: The dog may show weight loss due to loss of appetite and malabsorption of nutrients.
• Abdominal pain: Dogs may show signs of abdominal discomfort or pain, such as abdominal tension, arching of the back, or abdominal tenderness.
• Indigestion: Dogs may show signs of indigestion such as burping, bloating and farting.
• Anaemia: If gastric problems lead to chronic malabsorption of nutrients, the dog may show signs of anaemia, such as lethargy and pale mucous membranes.
• Bad Breath: Dogs may show signs of bad breath, which can be due to indigestion or oral problems caused by stomach problems.

If your dog shows any of these symptoms, it is advisable to take him to the vet for examination and treatment promptly.

How to Treat and Manage a Dog’s Stomach Bug？

If your dog is experiencing stomach issues, there are several things you can do to help manage their symptoms. However, it’s important to consult with your veterinarian, especially if your dog is very young, old, or has pre-existing health conditions.

1. Hydration is Key

• Water: Ensure your dog stays hydrated by offering fresh water at regular intervals. Dehydration can occur quickly with vomiting and diarrhea, so it's essential to keep your dog hydrated.
• Electrolyte Solutions: If your dog is vomiting or has diarrhea, your vet may recommend an electrolyte solution to help replenish lost fluids and salts.

2. Withhold Food Temporarily

• For mild stomach upset, you may be advised to withhold food for 12 to 24 hours to give your dog’s digestive system time to rest and recover. Always follow your vet’s guidance on this, as some dogs may require special care.

3. Bland Diet

• After the fasting period, introduce a bland diet like boiled chicken and white rice to help soothe your dog’s stomach. Gradually return to their normal food once symptoms improve.

4. Medications

• Your veterinarian may prescribe medications such as anti-nausea drugs, antibiotics (if there is a bacterial infection), or deworming treatments (if parasites are the cause). Always use medications as directed by your vet.

5. Probiotics

• Probiotics can help restore healthy gut bacteria after a bout of gastrointestinal upset. Some dog food brands and supplements contain probiotics, which can help regulate your dog’s digestive system.

6.Environmental Management

Keep your dog's living environment clean and hygienic, regularly sterilise kennels, toys and other items to avoid your dog coming into contact with dirty or irritating substances and to reduce the stimulation of the stomach by environmental factors.

7.Avoid Stress

Try to minimise the stress factors in your dog's life, such as sudden change of environment and excessive fright. If you need to travel or move with your dog, etc., try to make a smooth transition, such as letting your dog get used to the smell of the new environment in advance.

How to Adjust the Diet for Dogs with Stomach Problems?

I. Food Selection

• Easy-to-digest staple food

Low-fat meat: chicken and fish are good choices. Chicken can choose skinless chicken breast, boiled and chopped for the dog to eat. Fish (such as salmon, cod) is rich in high quality protein and relatively low fat content, easy to be digested and absorbed by the dog's stomach.
Rice and pasta: Cooked rice or pasta, which are rich in carbohydrates, can provide energy for your dog. Cooking them slightly softer will help ease the burden of digestion on your dog's stomach.
Pumpkin: pumpkins are rich in dietary fibre, vitamins and minerals and have a soft fibre texture. You can steam and puree pumpkin and add it to your dog's food in small amounts to help regulate gastrointestinal function.

• Special formula food

Prescription food: If your dog's stomach problems are severe, you can follow your veterinarian's advice and choose a prescription food that is specifically designed for gastrointestinal problems. These prescription foods are more scientific in the proportion of nutrients and help to improve your dog's gastrointestinal health.

II. Foods to avoid

• High fat food

Foods that contain a lot of fat, such as fatty meats and fried foods, should be avoided for your dog. High fat food is not easy to digest and will increase the burden on the dog's stomach, which may lead to excessive secretion of stomach acid, indigestion and other problems.

• Stimulating food

Spicy foods (such as chillies, peppers, etc.), onions, garlic, chocolate, grapes and sultanas are toxic to dogs as well as irritating foods and must be strictly prohibited from feeding. These foods can irritate your dog's gastric mucosa and trigger stomach upset or even more serious health problems.

• High Fibre Foods (in excess)

Although dietary fibre helps intestinal health, for dogs with gastric problems, excessive high-fibre foods (such as large amounts of celery, beans, etc.) may increase the digestive burden on the stomach and should be controlled in moderation during the dog's gastric problems.

III. Adjustment of feeding method

• Less food, more meals

Change the original feeding frequency, using less food and more meals. For example, change the original two meals a day to three or four meals a day. This can reduce the burden of the dog's stomach to digest food each time, so that the stomach has more time to digest and absorb food.

• Control the amount of food

Determine the right amount of food based on your dog's age, weight, activity level, and the severity of stomach problems. Avoid overfeeding to prevent the stomach from overexpanding and aggravating the symptoms of stomach problems. During the period of your dog's stomach problems, you can reduce the amount of food at each meal and gradually adjust it as your dog's condition improves.

• Slow eating

If your dog normally eats quickly, there are ways to make him eat more slowly. For example, use a slow food bowl, which is designed to make it more difficult for your dog to access food, thus slowing it down. Slow eating helps prevent your dog from swallowing too much air and reduces the likelihood of stomach bloat.

When to See a Vet

In most cases, mild stomach bugs in dogs resolve on their own with supportive care. However, there are situations where you should seek immediate veterinary attention, including:

• If your dog’s symptoms persist for more than 24 to 48 hours.
• If your dog is showing signs of severe dehydration, such as dry gums, sunken eyes, or lethargy.
• If you see blood in your dog’s stool or vomit.
• If your dog is very young, old, or has pre-existing health conditions.
• If your dog has a fever or is in significant pain.
