8 Signs Your Dog’s Faeces Reveal About Their Health
This article is not a substitute for veterinary intervention in the case of a sick animal. It is always better to be safe than sorry when your dog’s health is at risk. If you notice any abnormalities in your dog’s stools, it’s crucial to seek advice promptly from your vet.
1. Passing more stools than usual
Frequent or large volumes of stool often result from overfeeding. If you feed commercial food without precise measurements, consider following the manufacturer’s feeding guidelines carefully. Weigh your dog and the portion of food to make sure you are not exceeding their calorie needs. Remember to adjust main meal quantities if you give treats to avoid overfeeding.
Sometimes, an individual dog may not digest certain ingredients well. A gradual diet change to a formula containing different protein and carbohydrate sources can help improve stool volume and frequency.
2. Passing loose stools
Loose stools in dogs can be caused by various factors, including sudden dietary changes, stress, excitement, or changes in water quality, especially in puppies.
Infectious causes to be aware of include:
- Bacterial infections such as Campylobacter and Salmonella
- Viral infections like parvovirus
- Small intestinal bacterial overgrowth
Parasitic causes include:
- Roundworms, tapeworms and other worm infestations
- Protozoal parasites such as Giardia and Isospora
Other medical conditions that might cause loose stools are:
- Inflammatory bowel disease
- Exocrine pancreatic insufficiency
- Intoxication or ingestion of toxins
- Pancreatitis
- Intestinal foreign objects
- Neoplasia (tumours)
- Intussusception (intestinal telescope)
- Protein losing enteropathy
Because of the many possible causes, it is important to work with your vet to diagnose and treat your dog correctly.
3. Passing stools that are too hard (constipation)
Constipation may arise from:
- Foreign bodies such as swallowed stones, parts of toys, bones, or indigestible chews causing obstructions
- Medical conditions like tumours, polyps, rectal abscesses, anal tumours, or an enlarged prostate
- Hormonal issues such as hypothyroidism
- Parasite infestations including whipworms, which are common in some parts of the UK especially in kennelled dogs
- Neurological disorders affecting nerve function or conditions like megacolon, where intestinal muscles fail to move faeces properly
- Certain medications, including diuretics, antacids, opioids, and antihistamines
Diet plays a critical role in stool consistency; some dogs require more or less fibre. Too much or too little fibre can cause either diarrhoea or constipation. If your vet recommends fibre supplements, they are usually preferable to home additions like vegetables or bran as they allow precise dosing.
Insufficient water intake is a common contributor to constipation. Encouraging your dog to drink more can be achieved by soaking dry food before serving, offering wet food, or providing a canine water fountain. Adding a small amount of oil, like from canned sardines, to meals can help lubricate the intestines. Also, feeding smaller, more frequent meals may optimize digestion and reduce bowel workload.
4. Passing fresh blood in the stools
Small amounts of fresh red blood often indicate colitis, where the colon lining becomes inflamed. This can result from dietary indiscretions, infections, or other medical conditions. Extensive bleeding requires urgent veterinary attention as it may indicate blockages lower in the digestive system.
5. Passing dark blood in the stools
Black, tarry stools, medically called melaena, suggest bleeding higher in the digestive tract. This serious condition warrants immediate veterinary diagnosis and treatment.
6. Passing yellow or pale stools
Yellow or pale stools can be symptoms of pancreatic disease or infections such as giardia, requiring veterinary investigation.
7. Passing stools with a greenish colour
Green stools may indicate bile presence, which could mean digestive disturbances or toxin exposure such as rodent poison. Persistent green faeces should be checked by a vet without delay.
8. Passing mucus in the stools
Occasional small amounts of mucus are normal as it lubricates the intestinal lining. However, excessive mucus, especially if accompanied by blood or diarrhoea, signals possible intestinal inflammation or infection. Veterinary evaluation is essential to determine root causes and provide treatment.
Observing your dog’s faeces carefully provides early warnings of health concerns that otherwise might go unnoticed. Timely vet consultation ensures the best care and keeps your canine companion happy and healthy.
