Anaemia in Dogs: Causes, Symptoms, Treatment & Prevention

Anaemia in Dogs: A Complete Veterinary Guide for Pet Parents

Anaemia in dogs is a clinical condition that signals an underlying health issue. It occurs when red blood cell counts or haemoglobin levels fall below normal, reducing the body’s ability to carry oxygen. Recognizing the causes, signs, and treatment options is crucial for every responsible pet parent.

What is Anaemia in Dogs?

Anaemia itself is not a disease but a symptom of another underlying problem. It may result from blood loss, destruction of red blood cells, or inadequate production in the bone marrow. Veterinary diagnosis is essential to uncover the cause and guide treatment.

Causes of Anaemia in Dogs

  • Blood loss from injuries, internal bleeding, or surgery
  • Parasitic infestations (ticks, fleas, hookworms)
  • Chronic illnesses such as kidney disease
  • Immune-mediated destruction of red blood cells
  • Nutritional deficiencies (iron, B12, folate)
  • Toxins such as onions, garlic, or certain medications

Clinical Symptoms

  • Pale or white gums
  • Lethargy and exercise intolerance
  • Rapid breathing or fast heartbeat
  • Loss of appetite and weight loss
  • Weakness or fainting in severe cases

Diagnosis

Veterinarians diagnose anaemia with the following tests:

  • Complete Blood Count (CBC)
  • Blood smear to check red cell shape and parasites
  • Biochemistry to assess organ function
  • Urinalysis for kidney-related causes
  • Imaging (X-rays/ultrasound) to identify bleeding sources

Treatment Approaches

Targeted Therapies

  • IMHA: corticosteroids ± immunosuppressants; monitor for clotting.
  • Infections: antibiotics or antiparasitic drugs plus tick/flea control.
  • Blood loss: ulcer medication, deworming, or surgery.
  • CKD/Non-regenerative: EPO analogues, kidney care, nutrition support.

Home Care & Monitoring

  • Restrict activity until PCV/haematocrit normalises.
  • Give medications exactly as prescribed.
  • Regular rechecks with CBC at vet-recommended intervals.

Diet & Supplements

Most commercial dog foods already provide essential iron, folate, and vitamin B12. However, supplements may be prescribed if a deficiency or chronic blood loss is confirmed. Never give over-the-counter iron tablets without veterinary guidance—overdose can be fatal.

Avoid These Mistakes

  • Do not self-medicate with human supplements.
  • Do not delay veterinary diagnostics if your dog seems weak.
  • Do not rely on home remedies for serious cases.

Prevention Tips

  • Year-round tick, flea, and worm prevention
  • Balanced, vet-approved nutrition
  • Prompt treatment of GI issues like ulcers or diarrhoea
  • Keep toxins (onions, garlic, rat poison, zinc) away
  • Routine wellness exams, especially for senior dogs
Bottom line: Anaemia in dogs is a sign of an underlying issue, not a standalone disease. With timely diagnosis and targeted treatment, many dogs recover and regain their vitality.

FAQs

Are pale gums always a sign of anaemia?

Not always. Pale gums may also indicate shock or circulation problems. A CBC test confirms anaemia.

How fast can anaemia develop?

Blood-loss anaemia may occur within hours or days. Non-regenerative anaemia usually develops over weeks.

Can diet alone cure anaemia?

Only if caused by a nutritional deficiency, which is uncommon. Most cases require medical treatment.
