Southern Ocean Animal Hospital – 319 E Main St, Tuckerton, NJ 08087
TL;DR (Too Long; Didn’t Read)
Hematology is the study of blood and its disorders. At Southern Ocean Animal Hospital (SOAH), Daniel N. Pascetta, DVM, diagnoses and treats blood-related conditions such as anemia, immune-mediated diseases, and platelet disorders in dogs, cats, and other pets using advanced lab testing, imaging, and targeted therapies.
- Immune-Mediated Diseases: The immune system attacks red blood cells or platelets.
- Anemia: A lack of red blood cells, often due to bleeding, destruction, or bone marrow issues.
- Platelet Disorders: Problems with clotting or spontaneous bleeding.
- Diagnostics: Bloodwork (CBC), bone marrow analysis, imaging, and immune testing.
- Treatment: Immunosuppressive drugs, transfusions, antibiotics, and long-term management.
ELI5 (Explain Like I’m 5)
Your pet’s blood is like a delivery truck that carries oxygen and healing materials all over the body.
- Anemia = Not enough delivery trucks (red cells).
- Immune problems = The body mistakenly attacks its own trucks.
- Platelet disorders = The “repair crew” for cuts and scrapes isn’t working right.
Dr. Dan uses special microscopes and machines to find out what’s wrong with the trucks—and then helps fix them so your pet feels better again.
Key Takeaways (Bullet Summary)
- Hematology deals with blood and its components: red cells, white cells, and platelets.
- Immune-mediated diseases cause the body to destroy its own cells, leading to anemia or bleeding.
- Anemia can stem from blood loss, poor production, or red cell destruction.
- Platelet disorders affect clotting and may cause spontaneous bruising or nosebleeds.
- Diagnostics include CBC, blood smear, bone marrow analysis, imaging, and autoimmune testing.
- Treatment varies—ranging from corticosteroids to blood transfusions and immunotherapy.
- Ongoing management and early diagnosis are key for long-term outcomes.
Introduction
Blood is the foundation of life. It transports oxygen, delivers nutrients, removes waste, and supports immunity. When blood or its components malfunction, the entire body suffers.
At Southern Ocean Animal Hospital in Tuckerton, NJ, Dr. Daniel N. Pascetta, DVM, and his team specialize in diagnosing and managing hematologic disorders that affect pets’ red blood cells, white blood cells, and platelets.
Using state-of-the-art hematology analyzers, in-house laboratory diagnostics, and external reference testing, the team provides accurate, same-day assessments and long-term care plans for complex internal medicine cases across Ocean County, the Jersey Shore, and beyond.
SECTION 1: What Is Hematology?
Hematology is the branch of veterinary internal medicine that focuses on the blood and blood-forming organs.
It involves analyzing three key cellular components:
- Red Blood Cells (RBCs) – carry oxygen.
- White Blood Cells (WBCs) – fight infection.
- Platelets – help blood clot.
When one of these components becomes defective or is attacked by the immune system, pets may show vague symptoms such as weakness, pale gums, or unexplained bruising.
Dr. Pascetta’s extensive experience allows him to interpret these subtle signs and identify the underlying cause through precise testing.
SECTION 2: Immune-Mediated Diseases
What Are Immune-Mediated Diseases?
Immune-mediated diseases occur when a pet’s immune system mistakenly targets its own blood cells. Instead of attacking bacteria or viruses, it destroys vital red cells or platelets.
The two most common immune-mediated diseases in veterinary hematology are:
- Immune-Mediated Hemolytic Anemia (IMHA)
- Immune-Mediated Thrombocytopenia (IMT or ITP)
Immune-Mediated Hemolytic Anemia (IMHA)
Definition
IMHA occurs when the body’s immune system destroys its own red blood cells (hemolysis), causing a severe drop in oxygen-carrying capacity.
Symptoms
- Pale or yellow (icteric) gums
- Lethargy, weakness, collapse
- Rapid breathing or heartbeat
- Dark or red urine
- Fever
Diagnosis
- CBC & Blood Smear: Detects anemia and abnormal RBC shapes.
- Coombs Test: Identifies antibodies on red cells.
- Reticulocyte Count: Evaluates bone marrow response.
- Ultrasound & X-rays: Rule out underlying causes like tumors or infection.
Causes
- Idiopathic (unknown trigger)
- Secondary (due to infection, cancer, or certain drugs)
Treatment
- Immunosuppressive medications (Prednisone, Cyclosporine, Azathioprine)
- Blood transfusions if anemia is life-threatening
- Antibiotics or antiparasitic drugs if infection is the cause
- Careful monitoring of liver and kidney function during therapy
Prognosis
IMHA can be life-threatening, but many pets recover with aggressive treatment and consistent follow-up.
Immune-Mediated Thrombocytopenia (IMT / ITP)
Definition
A condition where the immune system destroys platelets, leading to spontaneous bleeding.
Symptoms
- Nosebleeds (epistaxis)
- Petechiae (tiny red spots) on gums or skin
- Bruising without trauma
- Blood in urine or stool
Diagnosis
- CBC: Shows low platelet count (<30,000/µL).
- Bone Marrow Biopsy: Evaluates platelet production.
- Infectious Disease Testing: Rules out tick-borne infections that mimic ITP.
Treatment
- Corticosteroids to suppress immune attack
- Vincristine injections to boost platelet release from marrow
- Blood or platelet transfusions in emergencies
- Monitoring via serial platelet counts
Prognosis
IMT often responds well to therapy, though relapse can occur. Long-term maintenance may be required in chronic cases.
SECTION 3: Anemia
What Is Anemia?
Anemia means a deficiency of red blood cells or hemoglobin, reducing oxygen delivery throughout the body.
Types of Anemia
- Regenerative Anemia: The bone marrow is responding by producing new cells (seen in blood loss or destruction).
- Non-Regenerative Anemia: The bone marrow fails to produce enough new cells (seen in chronic disease or bone marrow failure).
Symptoms
- Pale gums
- Fatigue or collapse
- Fast breathing or heart rate
- Cold extremities
- Loss of appetite
Causes
- Blood loss (trauma, parasites, ulcers, tumors)
- Immune destruction (IMHA)
- Chronic kidney disease (low erythropoietin)
- Bone marrow disorders
- Nutritional deficiencies (iron, B12)
Diagnosis
Dr. Pascetta employs several diagnostic methods:
- Complete Blood Count (CBC): Quantifies red cells, hemoglobin, and hematocrit.
- Reticulocyte Count: Measures immature red cells to assess marrow activity.
- Blood Smear Microscopy: Evaluates shape abnormalities (spherocytes, schistocytes).
- Iron Studies: Detect deficiencies or overload.
- Imaging: Identifies internal bleeding or tumors.
- Bone Marrow Analysis: Determines if production is impaired.
Treatment
- Address underlying cause: Control bleeding, treat infection, or stop immune destruction.
- Transfusions: Replace lost or destroyed red cells.
- Iron or B12 supplementation: Correct deficiencies.
- Erythropoietin therapy: Stimulates red cell production in chronic kidney disease.
- Corticosteroids: Manage immune-mediated destruction.
Prognosis
Most anemic pets recover when the underlying issue is corrected. Chronic or immune-mediated cases require ongoing management.
SECTION 4: Platelet Disorders
What Are Platelets?
Platelets are small blood fragments essential for clot formation and wound healing.
When platelet counts drop too low, or they malfunction, pets are at risk for uncontrolled bleeding even from minor injuries.
Common Platelet Disorders
- Immune-Mediated Thrombocytopenia (IMT) – Destruction by the immune system.
- Bone Marrow Failure – Decreased platelet production.
- Consumption Disorders – Platelets used up during massive bleeding or clotting (DIC).
- Inherited Disorders – Rare in specific breeds like Greyhounds or Cavalier King Charles Spaniels.
Symptoms
- Unexplained bruising or nosebleeds
- Blood in urine, stool, or vomit
- Gum bleeding
- Weakness due to blood loss
Diagnosis
- CBC: Determines platelet count.
- Peripheral Smear: Ensures automated counters aren’t underestimating due to clumping.
- Coagulation Profile: Detects clotting disorders.
- Bone Marrow Exam: Rules out decreased production.
- Infectious Disease Screening: Especially tick-borne diseases in New Jersey.
Treatment
- Immunosuppressive drugs: Prednisone, Cyclosporine.
- Transfusions: For severe bleeding.
- Vincristine therapy: Stimulates platelet release.
- Antibiotics or antifungals: If infection-related.
- Supportive care: Cage rest, soft bedding, and gentle handling.

Example Case
Case: Luna, a Golden Retriever
Luna presented with sudden lethargy and yellowing gums. Bloodwork revealed severe anemia due to Immune-Mediated Hemolytic Anemia (IMHA). Dr. Pascetta initiated high-dose corticosteroids, oxygen support, and transfusion therapy.
After several weeks of treatment and close monitoring, Luna’s red cell count normalized. She continues on a tapered maintenance dose with quarterly rechecks.
Timeline
- Day 1: Physical exam, blood tests, diagnosis of IMHA.
- Days 1–3: Hospitalization, transfusion, medication initiation.
- Weeks 2–4: Clinical improvement; ongoing lab monitoring.
- Months 1–3: Medication taper; secondary cause ruled out.
- Ongoing: Regular rechecks every 3–6 months.
What-If Scenarios
- What if anemia is ignored?
→ Pets may collapse due to oxygen deprivation; untreated IMHA can be fatal. - What if platelet disorders go undiagnosed?
→ Even minor injuries could cause uncontrolled bleeding or internal hemorrhage. - What if immune suppression is stopped too soon?
→ The disease may relapse; long-term monitoring is essential. - What if infections are the underlying cause?
→ Without identifying and treating them, immune suppression alone won’t resolve symptoms.
Most Common Hematologic Issues in Dogs & Cats
- Dogs: IMHA, IMT, anemia from parasites or cancer, chronic kidney anemia.
- Cats: Anemia secondary to chronic disease or FeLV, FIV, or bone marrow disorders.
- Other Pets (Ferrets, Rabbits): Less common, but similar testing principles apply.
Generational Relevance
- Boomers/Gen X: Prioritize continuity of care for aging pets with chronic diseases.
- Millennials: Value immediate diagnostics and preventative wellness testing.
- Gen Z: Expect digital reports, same-day results, and educational transparency from their veterinarians.
