As pet parents, we often find ourselves in the less glamorous role of scrutinising our furry friend's bathroom habits. While it might not be the most pleasant task, observing your dog's stool can be a window into their overall health.
One such indicator that often causes concern is the presence of mucus in dog poop. Although it might seem alarming at first, mucus plays a crucial role in your dog's digestive system. However, changes in its appearance or amount can be a sign that something's amiss.
In this comprehensive guide, we'll delve into the slippery subject of mucus in dog poop - decoding what's normal, what's not, and when it's time to ring the vet. From dietary misadventures to underlying health conditions, we'll explore the various causes, provide practical solutions, and arm you with the knowledge to ensure your pup's wellbeing.
Your dog's digestive system is lined with a layer called the mucosa. This layer contains goblet cells which manufacture and secrete mucus - a slimy substance that is predominantly water but also contains proteins which give it its gel-like consistency.
Mucus has many roles to play in the digestive system which include:
Small amounts of mucus in dogs' stools are quite normal and these are usually not noticeable. Faeces covered with a skin or jelly like coating of mucus are not normal, nor are large "blobs" of mucus in or around the faeces.
Anything that causes inflammation in the intestines will trigger an increase in mucus production in the gut to bolster its protective role.
As there are so many causes of abnormal mucus in dog poo, it is important to get a diagnosis from your vet before treatment.
The tests your vet may perform include:
If your dog only has one or two episodes of mucus in their stool followed by normal faeces, then this generally doesn't need treatment. Mucus caused by a dietary indiscretion or recent diet change will often respond to fasting for 24 hours or feeding a bland diet like boiled chicken and rice. Probiotics are also helpful for restoring the correct balance of microbes in the gut. Dietary and non-infectious causes of mucus in the stool can be treated with products like Peptosyl.
Treatment for chronic conditions like IBD and allergies is focused on therapeutic diets that contain specific proteins which are highly digestible along with other beneficial hypoallergenic ingredients.

You can help to prevent mucus in your dog's poo by:
• Making sure your puppy has their full course of puppy vaccinations and your dog is up to date with their vaccinations for their whole life.
• Stick to an effective intestinal parasite control program that is tailored to your dog's age and lifestyle.
• Pick up faeces in your yard daily and never hose them into the ground.
• Be vigilant when out and about and don't let your dog eat anything from the ground or drink dirty water. You may need to consider using a muzzle if your dog is a scavenger, particularly if they spend time off lead.
• Make any dietary changes slowly over the course of one week.
• Consider a sensitive digestion diet if the problem persists. Great options include Pro Plan Sensitive Digestion Lamb for adults, or Pro Plan Puppy Sensitive Skin & Stomach for puppies - either of these can be fed long term.
• Follow strict hygiene practices when feeding raw food or treats.
• Try a probiotic or digestive supplement like Paw Blackmores Digesticare as this can help create a healthy microbiome and reduce digestive abnormalities.
