Diarrhea in dogs is a very common complaint and is one of those unfortunate things that most dogs (and their owners) will have had to deal with at some point. Many cases tend to clear up by themselves, but other dogs can become seriously ill very quickly and may need hospital treatment to recover. The severity often depends on the age and general health of the dog. Diarrhea (or diarrhoea) in dogs can be acute (sudden) in a usually healthy dog, or chronic (long term) weight loss.
What causes diarrhea in dogs?
Food intolerance or allergies – even if you aren’t aware of an existing intolerance or allergy in your dog, these can develop over time
Poisonous substances and environmental toxins – check whether your dog could possibly have ingested a poisonous plant or toxic household chemical for example
Sudden change in diet – new foods should be introduced gradually, as an abrupt change can upset your dog’s digestion
Parasites like intestinal worms can irritate your dog’s gastrointestinal tract causing an upset stomach
Medication side effects, including antibiotics and other medicines
Stress or upset – anxiety about big changes in your dog’s life or other stresses can cause digestive upsets
Bacterial infections – these can occur more frequently in younger dogs
Other illnesses including liver, pancreas or thyroid disorders
Swallowing a foreign object – dogs can sometimes swallow indigestible objects that can’t be broken down and therefore cause an upset stomach.
Types of diarrhea in dogs
Diarrhea can either come from the small or the large bowel, and this has a bearing on how serious it can be for your dog.
Small bowel diarrhea usually means large amounts or very watery diarrhea which can lead to dehydration very quickly. With large bowel diarrhea your dog will be straining and passing smaller amounts of softer stools, sometimes also with mucous or blood.
What to do if your dog has diarrhea
Diarrhea is often relatively mild and may well resolve on its own. In these cases, if you have an adult dog that is otherwise healthy your vet may advise you to:
Provide plenty of clean, fresh water to avoid dehydration and encourage your dog to drink.
Feed little and often – although it’s tempting to hold off on the food when your dog has an upset tummy, good nutrition will help your dog’s digestive system to heal itself. Give something bland like bone broth or a small portion of white chicken meat with white rice, sweet potato or pumpkin for fibre.
Support the digestive system with probiotics and prebiotics using a supplement like Digestive Aid for Dogs. This will help to boost your dog’s immune system to support the whole body as well as helping to repopulate the friendly bacteria in your dog’s gut and restore the gut lining.
