Diarrhea in dogs can happen due to several factors. In this blog post, we are going to talk about the main causes of diarrhea in dogs and what should be done to prevent a worsening of the dog’s health.
Nocturnal diarrhea in dogs
Did you wake up in the morning and find your dog diarrhea? which may have led the dog to present this diarrhea. Nocturnal diarrhea in dogs can happen due to several factors such as:
- Infectious diseases;
- Food allergies;
- Food poisoning;
- Sudden change in diet.
Some diseases caused by viruses, parasites and bacteria can lead to an imbalance in the dog’s microbiota, leading to diarrhea.
- The main viruses that can lead to diarrhea in dogs are canine distemper virus, coronavirus, rotavirus and parvovirus in puppies.
In general, the viruses replicate in the gastrointestinal mucosa cells and can lead to lesions, thus reducing the absorption of liquids and nutrients that are excreted in the feces that become more liquid. Some virus diseases can lead to blood in the dog feces.
When leading to mucosal injury, changes in the gastrointestinal microbiota can also occur, which further worsens diarrhea in dogs. Viral diarrhea can be prevented by vaccines. In general, these diseases have no treatment for dogs, but treatments for secondary changes can be prescribed.
- About the diseases caused by bacteria, Escherichia coli, Salmonella and Shigella are the most frequent bacteria to lead to diarrhea in dogs. The canine gastrointestinal microbiota is mostly made up of bacteria.
When foreign bacteria start to replicate in the gastrointestinal tract, the microbiota try to avoid this replication. However, the excess of foreign bacteria causes a dysregulation of the microbiota, reducing the absorption of nutrients, leading to diarrhea.
The treatment for bacterial diarrhea may involve the use of some antibiotics and the reconstitution of healthy microbiota for the intestine of dogs.
- Parasitic diarrhea can occur mainly due to parasites such as Giardia, Ancylostoma caninum, Toxocara canis and Dipylidium sp. These parasites have different cycles, but they all affect the functioning of the gastrointestinal system leading to diarrhea.
Parasitic diseases can be avoided through periodic feces laboratorial examinations and the use of oral antiparasitic drugs. Treatment consists of antiparasitic drugs, microbiota replacement and nutrient supplements when necessary.
Food allergies can affect some breeds of dogs, it can be a hereditary trait, so you should avoid breeding these dogs.
Dogs with food allergies should see a veterinary gastroenterologist to find out the cause of the allergies through testing. After the diagnosis, the dog should avoid consuming the food that causes the allergy.
For some dogs it may be necessary to consult with a veterinary nutritionist so that a balanced natural diet is prescribed. For other dogs it may also be necessary to use specific industrial diets for the gastrointestinal tract. Thus, avoiding allergies that lead to diarrhea.
Consumption of spoiled or contaminated food can carry toxins into the gastrointestinal tract. These toxins can unbalance the microbiota leading to diarrhea.
Intoxicated animals should see a veterinarian. In many cases, dogs can receive fluid therapy to reduce the effects of toxicants. Procedures such as gastric lavage can be performed in some situations.
Treatment includes replacement of fluids, gastrointestinal microbiota, and nutrients. Some dogs can become dehydrated quickly due to increased symptoms such as vomiting and diarrhea. Emergency care by a veterinarian is required.
Sudden change in diet
Changing the dog’s diet without an adaptation can led to changes in the composition of the dogs’ microbiota, which can result in diarrhea.
Changing the dog’s diet should be done progressively as shown below:
- 1st and 2nd days: 75% Old food + 25% New diet.
- 3rd and 4th days: 50% Old food + 50% New diet.
- 5th and 6th days: 25% Old food + 75% New diet.
- 7th day onwards: 100% New diet.
