Vet Approved Guide: Aplastic Anemia in Dogs – Causes, Signs & 2025 Treatment Strategies 🐶🐾 

By Dr. Duncan Houston BVSc

Aplastic anemia (also called pancytopenia) occurs when a dog’s bone marrow fails to produce red cells, white cells, and platelets. This serious and potentially fatal condition requires prompt diagnosis and supportive therapy to improve outcomes. 🛡️

🔎 What Is Aplastic Anemia?

In aplastic anemia, healthy bone marrow is replaced by fat, significantly reducing the production of vital blood cells, including RBCs, WBCs, and platelets.

📋 Common Signs to Watch

• Pale gums or mucous membranes
• Weakness, lethargy
• Recurring infections and fever
• Bleeding issues: nosebleeds, bruising, bloody urine or stools, petechiae

🔍 Potential Causes

Aplastic anemia ranges from immune‑mediated to toxin or drug-induced:

• Infections: parvovirus, tick-borne rickettsial diseases (e.g., ehrlichia)
• Certain medications: NSAIDs, chemotherapy agents, albendazole, antibiotics
• Hormones: estrogen exposure
• Radiation exposure or immune-mediated bone marrow suppression

🩺 Diagnosing Aplastic Anemia

• Complete blood count (CBC) reveals pancytopenia and nonregenerative anemia
• Bone marrow aspirate & biopsy: confirms low cellularity and fat infiltration
• Additional testing to rule out infections, drug exposures, or underlying diseases

🛠️ 2025 Treatment Strategies

1. Hospitalization & Supportive Care

• IV fluids, nutrition, and rest
• Blood transfusions to address severe anemia or thrombocytopenia
• Antibiotics for infections and infection prevention

2. Immune Suppression

• Cyclosporine A is commonly used to prevent immune attack on bone marrow
• Steroids (prednisone/prednisolone), mycophenolate, or azathioprine may also be used

3. Bone Marrow Stimulators & Advanced Care

• Recombinant growth factors (e.g., erythropoietin, G‑CSF) support recovery
• Eltrombopag has shown success in sustaining platelet counts in dogs
• Bone marrow transplant is a consideration for idiopathic or refractory cases

📈 Prognosis & Long-Term Outlook

While prognosis varies, young dogs and cases with known causes that are promptly treated may recover over weeks to months. Idiopathic or severe cases have a guarded prognosis, and relapses are possible.
