Top 10 tips to prevent diarrhoea in dogs

Written by Dr. Nandita Mirajkar, BVSc & AH, PhD, Scientific Affairs Lead at ilume

If your dog has diarrhoea, you’re not alone. Diarrhoea is one of the most common conditions veterinarians encounter in dogs, and almost 29% of dogs may have experienced diarrhoea within the previous month.1, 2

Diarrhoea can be caused by a range of factors, most commonly related to something your dog ate. Check out Part 1 of this series on diarrhoea - What causes diarrhoea in dogs? to understand more.

Top 10 tips to prevent diarrhoea in your dog

While you may not always be able to prevent it, there are some steps you can take to reduce the risk of your dog developing diarrhoea.

  • Prevent scavenging.

    Try to prevent your dog from eating things off the road and ensure that food waste, leftovers, and garbage are inaccessible to them. This will reduce the risk of them eating something that may cause diarrhoea due to an infection or gut inflammation.3, 4

  • Avoid feeding table scraps.

    Resist begging and avoid sharing your food with your dog as many human foods are not easily digested by dogs, and may even be toxic for them.5

  • Provide appropriately portioned meals on a regular schedule.

    Help prevent overeating in your dog by maintaining scheduled mealtimes with accurately weighed portions.6-8

  • Eliminate household hazards.

    Dog-proof your house to prevent access to potentially hazardous materials or objects, as mistaken swallowing can damage the gut.6, 8, 9

  • Avoid feeding raw food and instead provide nutritionally complete and balanced cooked foods.

    Avoid raw dog foods, especially raw meat or offal, as they have a higher risk of carrying food-borne
    , and bones may additionally also cause damage to the digestive tract.8, 10 Cooking kills harmful food-borne microbes, and providing lightly cooked fresh food is safer for both, you, and your dog. A gentle word of caution for home chefs - home-prepared dog food may be deficient in many nutrients 11, and is associated with a higher risk of diarrhoea3.

  • Transition diets slowly.

    Avoid sudden changes in diet, as the gut and microbiome require time to adjust to the change.7-9

  • Identify and eliminate ingredients that your dog is intolerant or allergic to.

    If your dog is diagnosed with intolerance or allergy to a particular ingredient, eliminating it from their diet is the best approach to soothe the gut and prevent future reactions.7-9

  • Reduce stress and anxiety.

    Change in the environment, family, travel, boarding and severe weather may all be significant stressors for your dog that may cause diarrhoea. Ask your veterinarian about probiotics or other measures to combat stress-related diarrhoea, especially if your dog has an anxious temperament or you’re aware of upcoming stress triggers.6-8

  • Stay up to date with your dog’s immunisations and deworming schedule.

    Ensure they get their doses and boosters as per their schedule to provide protection against infectious agents and worms.3, 7

  • Ensure early intervention for any medical condition.

    Always keep an eye out for common signs that your dog is unwell and don’t hesitate to consult your veterinarian if something seems amiss. While you may not be able to prevent many diseases from occurring, providing early medical treatment may reduce complications of other diseases, and in turn, related symptoms such as diarrhoea.

Pro Tip: Select fresh, nutritionally balanced, whole, high-quality, gently cooked dog food without artificial preservatives, flavours, and colours.

If you’ve looked at the above tips to prevent diarrhoea in your dog, you’ve probably realised that in terms of dog food, you’re better off serving cooked food that suits your dog’s gut. Even amongst cooked foods, different processing methods not only impact the nutritional content and digestibility of the food, but may also have potential health impacts.12-16

That’s the reason that gently cooked fresh foods using natural, whole, and high-quality ingredients have risen in popularity. They inherently overcome potential issues associated with kibble, canned wet food, and raw food by mildly cooking foods at lower temperatures, and by avoiding the use of artificial additives.

Fresh, gently cooked foods may reduce the risk of foodborne infections, inflammation-associated harmful compounds (e.g., Maillard Reaction Products, Advanced Glycation End-products), some adverse food reactions (associated with artificial food additives or increased allergenicity of some proteins), and in turn, potentially also diarrhoea in dogs.15-18 High-quality commercial products often also have the benefit of being formulated by nutritionists to be complete and balanced.

Compared to kibble, fresh and mildly cooked food is more digestible and may have some favourable effects on your dog’s poop such as maintaining the quality, while reducing how much and how often they defecate.19-22 Eating gently cooked fresh food using whole ingredients may also be associated with significant gut microbiome changes, immunomodulatory effects, and general health maintenance in dogs.19, 20, 22-25
