Dog Passing Blood: What to Do and When to Seek Help

Our dogs provide us with immense joy, so seeing them unwell can be distressing. When a dog is passing blood in their faeces, it signals the need for swift attention. Understanding the cause and acting promptly can greatly improve the chances of recovery, so it’s important to recognise the signs and know when to contact your vet.

Recognising Symptoms in Your Dog

The presence of blood in a dog’s stool can indicate several serious issues affecting the digestive tract. It is especially important to watch for these symptoms alongside blood:

• Vomiting
• Complete loss of appetite
• Lethargy or weakness
• Diarrhoea or changes in stool consistency

Blood in stools can appear bright red, often indicating bleeding from the lower digestive tract, or a darker, tar-like consistency when bleeding occurs higher in the digestive system. Small breeds may be more commonly affected by certain conditions causing bloody stools.

Common Causes of Bloody Stools in Dogs

One diagnosed condition is Haemorrhagic Gastroenteritis (HGE), where inflammation leads to bleeding in the dog’s digestive tract. The exact cause remains unknown but stress and hyperactivity could be contributing factors. However, blood in stool can also arise from other causes:

• Internal parasites such as hookworms or Giardia
• Dietary indiscretions or ingestion of harmful substances
• Trauma or injury to the gastrointestinal tract
• Inflammatory bowel disease
• Infections or anal sac issues
• More serious causes like tumours or parvovirus in puppies

Regular worming is essential to prevent parasite infestations that can cause bleeding and to help identify issues early by checking your dog’s stool periodically. Finding puppies from reputable sources can ensure you start your pet’s life with a good health foundation.

Diagnosing Bloody Stools

Your vet can often diagnose conditions like HGE through blood tests and stool analysis, which helps detect underlying bacterial infections or parasites. Bacteria such as Clostridium may play a role in HGE, although the precise cause is yet to be confirmed.

It is important that vets rule out parasites first since treatment differs significantly. Worm infestations are a common yet treatable cause of blood in stools.

Treatment Options and Care

For HGE or bacterial infections, vets typically prescribe antibiotics and supportive care, including intravenous fluids to address dehydration, which is critically dangerous to liver and kidney function. Hospitalisation may be necessary to provide close monitoring and treatment.

Anti-nausea medication is often given to reduce vomiting, aiding recovery and comfort. Most dogs, when treated early and appropriately, recover fully within a few days, but delayed treatment can be life-threatening.

Preventing and Monitoring Your Dog’s Health

Routine worming and regular veterinary check-ups remain the cornerstone of prevention. Particularly for puppies and older dogs, these visits provide an opportunity for vaccination and health screenings. Cavalier King Charles Spaniel puppies, for example, benefit from early health monitoring due to breed sensitivities.

When to Contact Your Vet Immediately

If you observe blood in your dog’s stools, accompanied by any worrying symptoms such as severe lethargy, persistent vomiting, difficulty in passing stools, or changes in behaviour, seek veterinary attention promptly. Early diagnosis can make all the difference to treatment success.

What Is Haemorrhagic Gastroenteritis (HGE)?

Quick Answer: HGE is an acute condition causing sudden severe gastrointestinal bleeding and inflammation, commonly in small dogs, requiring urgent veterinary treatment.

HGE causes your dog’s digestive tract to bleed and inflame rapidly, often leading to vomiting and bloody stools. Although the precise cause remains largely unknown, stress and bacterial involvement such as Clostridium are suspected contributors. The most important fact is recognising symptoms early and ensuring your pet receives immediate veterinary care including intravenous fluids to prevent dehydration and prescribed antibiotics to combat infection.

Dogs affected by HGE can recover quickly with hospital care, but the condition can rapidly become life-threatening if untreated.

Why Does My Dog Have Blood in Their Stool?

Quick Answer: Blood in your dog’s stool can be caused by infections, parasites, injuries, or more serious conditions like haemorrhagic gastroenteritis, all requiring vet diagnosis.

Blood may appear bright red if bleeding is from lower intestinal areas or black and tarry if from upper digestive tract. Causes vary widely from mild to serious, including internal parasites like hookworms, dietary issues, or gastrointestinal diseases. Since treating the wrong cause can worsen your dog’s condition, professional diagnosis and early intervention are vital.

Keep a close eye on your dog's overall wellbeing, including appetite and energy levels, and always provide clean water to aid recovery and prevent dehydration.

Summary and Next Steps

Seeing your dog pass blood in their faeces is understandably alarming, but early action can provide the best outcome. Always contact your vet to diagnose the issue promptly. Regular worming, careful observation of symptoms, and routine veterinary checks support your dog’s long-term health and wellbeing.

If you are considering bringing a new dog into your family, choosing a healthy puppy from reputable reputable breeders can help prevent future health challenges. And remember, should your dog develop any warning signs, timely vet visits save lives and promote a swift return to happy, healthy days.
