As every dog owner knows, observing the condition of a dog's stool is one of the ways to obtain information about the dog's health! Healthy and normal stool is well-formed and consistent. Occasional diarrhea is sometimes a natural purification process of the body, but persistent diarrhea (generally more than two days) may be a warning signal of health problems.

The causes of diarrhea in dogs are intricate and complex. Let's explore the secrets behind dogs' diarrhea together.

01 Dietary Diarrhea  

When a dog suffers from indigestion, it is important to first check its diet. For example, whether there has been a change in the dog's recent food, especially if the food was replaced without a transition period, which may be one of the factors leading to diarrhea. In addition, food intolerance or food allergies are also potential causes of diarrhea in dogs.

Furthermore, as scavengers, dogs may eat some unhealthy "food" such as garbage or kitchen leftovers. This can also cause acute diarrhea in dogs, as these foods may contain pathogenic bacteria that are harmful to them. In most cases, this type of diarrhea will subside on its own within a day or two.

Symptoms: If your dog suddenly loses appetite, has loose stools with a foul odor, but remains relatively energetic, it may be suffering from dietary diarrhea.

  02 Viral Diarrhea 

Some common viruses include canine parvovirus and canine coronavirus, and puppies with incomplete vaccinations are highly susceptible to infection.

Canine Parvovirus

Canine parvovirus is a non-enveloped, single-stranded DNA virus that can infect canines through minor antigen transfer and natural mutation. Canine parvovirus disease is a highly contagious intestinal disease in dogs, causing severe vomiting, diarrhea (with bloody stools), loss of appetite, high fever, severe dehydration, and even death in puppies and elderly dogs.

Canine Coronavirus

Canine coronavirus is an enveloped, spherical, single-stranded RNA virus that can cause severe enteritis syndrome in dogs, characterized by frequent vomiting, diarrhea, depression, anorexia and other symptoms. Occasionally, a small amount of blood can be seen in the stool. Clinically, it is difficult to distinguish from canine parvovirus, except that the infection duration of this disease is longer, intermittent, and may recur. It exists in various animals, and dogs, cats, wolves and foxes are all likely to be infected.

Viral diarrhea itself is rarely fatal and is a relatively mild disease, and sometimes most owners cannot distinguish the symptoms. However, when puppies are infected, the condition will be more severe. If a puppy is infected with both canine parvovirus and canine coronavirus, the mortality rate can be as high as 90%.

 03 Parasitic Diarrhea 

As we all know, intestinal parasites (such as Tritrichomonas foetus, Giardia, worms, Toxoplasma gondii, Cryptosporidium) are common causes of diarrhea in dogs; some parasites may appear as small white dots or particles in the dog's stool, and a veterinarian needs to test for parasites to confirm infection. Regular deworming of dogs is one of the important measures to prevent diarrhea.

Tritrichomonas foetus

Tritrichomonas foetus belongs to the Parabasalia, Trichomonadea, Trichomonadidae. It is a protozoan (single-celled organism) that can cause chronic large intestinal diarrhea. They colonize the terminal ileum, cecum and colon of cats, causing large intestinal diarrhea in cats, and are not common in dogs.

Trichomonal vaginitis in humans is mainly caused by Trichomonas vaginalis, which is unlikely to be transmitted from cats to humans, and vice versa. However, due to the poor host specificity of Tritrichomonas foetus, the possibility of zoonosis needs to be considered, and infected kittens with diarrhea should be carefully cared for.

Giardia

Giardia is a protozoan, a single-celled organism, which mainly parasitizes in the duodenum, jejunum and anterior ileum of dogs and cats, and can cause small intestinal diarrhea (occasionally large intestinal) in dogs and cats. Both humans and animals can be infected, and different species of Giardia can infect different animals: for example, Giardia agilis can infect amphibians; Giardia muris can infect reptiles, birds, humans and many mammals.
