Changed Dog Food And Dog Has Diarrhea: The Best 24 Reason

If we changed dog food and dog has diarrhea, we should know that previous food may have caused this reaction. To avoid another response from the new dog food, we need to know if this food is toxic, possibly causing diarrhea.

This condition may lead to further complications like constipation because of dehydration. I suggest avoiding any food that will cause diarrhea because of its toxic effect.

The most common symptoms are vomiting and diarrhea. Some animals may only vomit or have diarrhea, depending on the toxins that caused this reaction.

Food that causes diarrhea

Foods containing high fats, like fried foods, may cause diarrhea. Large amounts of carbohydrates may cause an increase in the secretion of gastric acid, increasing the risk for this condition.

Animal proteins are essential but must be highly digestible because these undigested proteins will affect the animal’s digestive tract.

A diet with high levels of fiber may also bring about this condition.

As I said initially, changing dog food can cause these symptoms because everything is new to your dog’s digestive system.

Equally important are training mistakes where long rest periods following a meal or exercise will increase these symptoms.

These symptoms may also be present in some dogs with inflammatory bowel disease.

If the dog has diarrhea or is vomiting, I recommend that you stop your dog’s meal plan for two days to see if these symptoms resolve themselves.

If they don’t, you should take your dog to a veterinarian for further diagnostics and treatment.

Dogs are carnivores, which means that they require a diet high in animal protein. If their diet is changed suddenly to one containing large amounts of carbohydrates, dogs may develop diarrhea or other digestive system problems.

As I have always said, dogs are omnivores and can eat vegetables and meat.

Consequently, they can usually adapt to dietary changes without developing diarrhea due to changing dog food and seeing the vet for a checkup.

I suggest that you consult your veterinarian before making any dietary change in your dog’s diet.

The Veterinarian will help you choose the best food for your dog and avoid foods that may cause diarrhea.

The most common causes for diarrhea in dogs are 

1) Changing dog food diet

This can be a problem if the food you feed your dog contains elements not recommended for a specific digestive system like high fiber, fat, or protein levels.

I recommend avoiding changing brands frequently, but try introducing the new food gradually when this is necessary.

2) Food allergies

This type of reaction is the most common cause of canine diarrhea and vomiting that we see in our clinic.

The symptoms may vary, but they usually start within a few hours after ingesting the food, including itching, vomiting, diarrhea, and bloody stools. 

The main symptom to look out for is the reaction time after feeding your dog. For instance, if your dog has no signs of intestinal irritation at mealtimes until the next day, this may indicate that your pet is allergic to his food.

You can consult your Veterinarian or carry out a simple test at home to determine which foods are causing these reactions.

Before thinking about changing your dog’s food, I recommend you do this to avoid any complications.

3) Dietary indiscretion

This occurs when your dog eats something that he shouldn’t or ingests poisonous like medication, plants, or other chemicals. 

4) Infections

Some of the most common infections that cause diarrhea in dogs are caused by viruses, parasites, and bacteria.

5) Toxins

Though less common, toxins such as drugs may cause vomiting and diarrhea and other symptoms such as lethargy and high body temperatures.

6) Intestinal diseases

Some of the most common intestinal diseases that bring about symptoms of diarrhea are inflammatory bowel disease, infections, or colitis.

7) Cancer

This is one of the most dreaded conditions. When your dog has cancer, you will notice that he loses his appetite and drinks more, resulting in vomiting or diarrhea. 

8) Dehydration

Dehydration usually occurs when there is blood loss via vomiting or diarrhea. This can be caused by various factors, including intestinal diseases and inflammations.

9) Pancreatitis

Pancreatitis is a condition that causes digestive enzymes to become active in your pet’s pancreas. These enzymes cause irritation and inflammation to the pancreatic tissue, resulting in vomiting and diarrhea.

10) Trauma

In some cases, trauma to your dog’s digestive tract can result in diarrhea.

11) Exocrine pancreatic insufficiency

This condition occurs when there is a lack of enzymes responsible for digesting fats. This will cause an alteration in the digestion of your dog’s food, resulting in malabsorption into his bloodstream and then intestinal irritation.

12) Chronic renal disease

This condition is common in older dogs, and, as its name suggests, it means that your pet’s kidneys are not functioning correctly.

Kidney failure can cause many symptoms, but diarrhea and vomiting are some of the most commonly seen ones.

13) Urinary tract infection

This is usually caused by bacteria, which pass through the urinary tract and cause irritation. You will usually see this confirmed by blood in your pet’s urine, as well as an increase in his urination frequency.

14) Pancreatic insufficiency

When your dog has pancreatic insufficiency, he won’t digest fats due to the low levels of pancreatic enzymes.

This results in malabsorption into his bloodstream, causing irritations and inflammations throughout the digestive tract. 

15) Liver diseases

The liver is responsible for metabolizing proteins, so it will affect your pet’s protein absorption through the whole digestive system if it is not functioning correctly. As a result, you may see symptoms of diarrhea, vomiting and loss of appetite.

16) Inflammatory bowel disease

This is a condition that causes inflammation in your dog’s intestinal tract. You’ll notice this irritation will result in fever, vomiting and diarrhea.

17) Protozoal infections

These are parasites like Giardia or Cryptosporidium, which live in your dog’s intestine and cause irritation and inflammation.

Giardia is the most common of these parasites and it usually passes from one dog to another through leach contamination.

18) Parasites

There are a variety of parasites that can invade your pet’s intestines, such as roundworms, whipworms, or tapeworms, resulting in symptoms of diarrhea.

19) Ingestion of foreign objects

Choking or intestinal blockage via ingestion of a foreign object is common in dogs and it can cause symptoms such as vomiting and diarrhea. Your dog may also have a low body temperature and show signs of lethargy.

20) Food allergies

Dogs can be allergic to all sorts of food and ingredients, resulting in vomiting and diarrhea. The most common foods that dogs show allergies to include: beef, dairy products and chicken.

21) Urinary tract obstruction

This is a condition that usually occurs mainly in male dogs, affecting the urinary tract system. You will notice this obstruction as your dog will refuse to eat, vomit and show a reduced interest in going out for a walk.

22) Gastrointestinal parasites

Dogs can be affected by all sorts of intestinal parasites, resulting in vomiting and diarrhea. Dogs usually pick up these parasites from eating rodents or insects carrying the parasite eggs.

23) Bacterial infection

Different types of bacteria cause the symptoms of vomiting and diarrhea. The most common ones include E Coli, salmonella and clostridium perfringens.

24) Unknown causes

In some cases, you may not be able to figure out why your dog is experiencing diarrhea. In those cases, it’s best to take him for a checkup at the vet as it can be a sign of something more serious.

Conclusion

Vomiting is a symptom that needs to be handled immediately. If left untreated, it can result in more severe conditions such as vomiting blood or intestinal blockage. 

If you are concerned about your dog’s constant diarrhea, then consult with your vet right away to discover its cause and start treatment.

 Dogs that experience vomiting or diarrhea regularly should be fed a healthy diet to reduce the risk of being affected by something more serious.

The most important thing is that you take care of your dog’s needs, so they are healthy and happy! Thank you for your visit today. I will be pleased to read this article.
