Why Does My Dog Have Diarrhea?

You probably see your dog snacking on various things. In addition, puppies are also predisposed to bite because their teeth grow slowly. But, you may sometimes notice a change in your dog’s stool that may be of concern. You may be wondering, “Why does my dog have diarrhea?” when this happens. Let’s see what happens with diarrhea in dogs.

What causes diarrhea in dogs?

Diarrhea has many causes. However, you must identify the cause before you can provide a home remedy. Better yet, you can take your dog to the vet for the necessary laboratory tests. Dog diarrhea can be caused by many factors, from very simple eating problems to life-threatening diseases. Find out what causes diarrhea in dogs.

Poor diet

Poor diet can often lead to stomach problems and diarrhea in dogs. In addition, you probably give your dog human food that disrupts his digestive system. If you regularly give your dog unhealthy food, it can also lead to diarrhea. High quality dog food can be the best staple food for your dog and some safe human foods for dogs such as occasional treats.

Sensitive stomach

Some dogs have sensitive stomachs. In addition, some breeds are predisposed to have a sensitive stomach. When a dog has a sensitive stomach, it is important to give them the right foods to avoid digestive problems. In addition, sensitive stomachs can also be characterized by an allergy to certain foods, including certain cereals, which can trigger diarrhea.


Overeating can result in such a large amount of droppings for your puppy or dog. However, even if your dog poops more frequently than normal, it may not really be diarrhea. On the other hand, if poo is formed and not very watery, it is probably not diarrhea. But if you overfeed your dog or puppy and he starts pooping irregularly, you can reduce his food intake to avoid diarrhea.

An abrupt change in diet

A sudden change in diet can cause changes in your dog’s digestive tract. This sudden change in diet can trigger regurgitation or diarrhea. If you plan to change your dog’s diet, it is best to slowly introduce the new diet before feeding your dog exclusively with the new diet. It may be a new brand or type of food, but your dog needs some time to get used to it in order to avoid digestive problems.


Stress induces various physiological responses in dogs. In addition, it can be caused by many things ranging from the environment to food. In addition, mishandling your dog or the presence of hostile dogs can be a source of stress for any dog. Once stressed, it can lead to diarrhea, vomiting and other physiological reactions in an attempt to adapt to the condition or situation.

Other health issues

There are many canine diseases whose symptom is diarrhea. However, it can be difficult to distinguish one disease from another without proper laboratory analysis to determine the cause of your dog’s disease. Diarrhea can also be accompanied by vomiting or foam in the mouth, which can threaten your dog’s life if left untreated. Here are some of the health problems of dogs that can cause diarrhea:

  • Nutritional imbalance or inability to metabolize certain nutrients
  • Idiopathic inflammatory bowel disease
  • Gastric ulcers
  • Bowel motility disorders
  • Food allergy
  • Poisoning

  • Parvovirus infection

Why does my dog have diarrhea?

Dog diarrhea can be caused by many things. However, diarrhea is the reaction of your dog’s body to various things. In addition, it can be an indicator of more serious illnesses. Diarrhea is an attempt to excrete substances that irritate your dog’s digestive tract. This is why diarrhea also appears in various infections and infestations.

If diarrhea is caused by a change in diet, then your dog’s intestinal motility is increased in an attempt to get rid of this new food that has suddenly entered his system. On the other hand, infections of the digestive tract cause irritation and motility which also cause diarrhea in dogs. In addition, certain viruses, bacteria and parasites directly attack your dog’s digestive tract, resulting in diarrhea.

When you notice that your dog’s droppings have suddenly changed shape and color, look closely at your dog within hours to determine what other signs and symptoms may appear soon after. In addition, diarrhea and the type of droppings that your dog excretes are also a sign of his general health. For example, when you notice signs of diarrhea, it is best to consult a veterinarian immediately or at least provide home remedies during observation.

First aid in case of canine diarrhea

When you notice the first signs of diarrhea, do not ignore it because it can get worse, depending on its cause. There are ways to manage dog diarrhea at home before it puts its life at risk. However, you should always seek the help of a veterinarian if your dog’s diarrhea persists. Here are some ways to give first aid to your dog who suffers from diarrhea:

  • Give it enough water and electrolytes to avoid dehydration
  • Provide easy-to-digest foods
  • Get your dog out of stressful living conditions


Why does my dog have diarrhea? Diarrhea can be caused by many things and only a laboratory test can surely indicate the real cause of your dog’s diarrhea. However, not all canine diarrhea is life-threatening and does not require medical attention. Your dog may also simply be adjusting to a new food or is stressed by its new environment. However, give first aid immediately to any dog suffering from diarrhea.
