Rotten Leg, High Fever, No Care – Meet Casey

On the way to the rescue house, I saw a dog dragging a badly injured leg across the road. I had visitors waiting at the house, so I quickly checked who´s house she belongs to and then went first to the Rescue House. After I was done , I went back to check. She was hiding in a dark corner at that local house. The leg looked even worse up close. Bone exposed, tissue rotting. I asked who she belonged to and took her straight to the clinic. Her name is Casey.

 


First assessment at the clinic

The vet confirmed what was already obvious — the right hind leg can’t be saved. The damage is too severe. Amputation will be needed, but not right away. First, she needs to be stabilized.

She also had discharge from her eyes, so they tested for distemper. The result came back negative. She had a high fever (40.6°C) and was covered in ticks. On top of that, there was a heavy discharge from her vagina, and the vet suspects pyometra — a uterine infection that can quickly become life-threatening if left untreated.


Blood results and what they mean

We ran a full blood panel to get a better understanding of her condition. Here are the results:

ParameterResultNormal Range
WBC (White Blood Cells)27.62 × 10⁹/L6.00–17.00
NEU (Neutrophils)24.44 × 10⁹/L3.00–12.00
NEU %88.5%60–77%
RBC (Red Blood Cells)4.04 × 10¹²/L5.50–8.50
HGB (Hemoglobin)6.3 g/dL12.0–18.0
HCT (Hematocrit)22.34%37.0–55.0
PLT (Platelets)12 × 10⁹/L165–500
MCHC28.3 g/dL31.0–39.0
RDWc19.9%14.0–20.0

In short:

  • White blood cells and neutrophils are very high, which confirms a strong ongoing infection — likely from both the leg wound and the uterus.

  • Red blood values are low — she’s clearly anemic, most likely due to tick-borne disease.

  • Platelets are critically low, which increases the risk of bleeding and makes surgery unsafe right now.

  • RDW is elevated, meaning her body is trying to regenerate red blood cells, but not efficiently.

  • MCHC is also low, another typical sign of anemia.


What we’re doing now

Here’s the treatment plan the vet started right away:

  • Antibiotics for general infection

  • Antibiotics for suspected blood parasite

  • PCR test to identify the exact parasite (results expected within 24h)

  • Iron supplements

  • IV fluids for rehydration

  • Tick and deworming treatment

  • Daily wound care until she’s strong enough for surgery


How she’s doing

She’s been mostly quiet, but responsive. This morning she ate some chicken, drank well, peed — no poop yet, but the fever is gone. The bandage will be changed again this afternoon.

We’ve gone ahead with the PCR test to confirm which parasite we’re dealing with so we can treat it more precisely.

For now, she’s safe and getting the care she needs.

Update: June 23rd 2025

PCR Results: Ehrlichia Detected

We received the PCR results, and Casey tested positive for Ehrlichia spp. with a Ct value of 31.03. All other pathogens (Babesia, Mycoplasma, Anaplasma, Borrelia) were negative.

What is Ehrlichia?

Ehrlichia is a tick-borne blood parasite that infects white blood cells and can cause serious health issues if left untreated. It often leads to:

  • Anemia (low red blood cells)

  • Thrombocytopenia (low platelets, which we’ve already seen in Casey)

  • Lethargy, fever, and weight loss

  • Organ damage in later stages

The infection matches her blood results and symptoms — low red cells, low platelets, and high white blood cells all point to ehrlichiosis as a major underlying cause.

Treatment has already started and includes targeted antibiotics (usually doxycycline) and supportive care like fluids, iron supplements, and parasite control. Now that we know exactly what we’re dealing with, the vet can adjust the medication plan accordingly.

We received an update from the clinic yesterday.

Casey had a fever during the night, but after receiving her daily anti-inflammatory medication, her temperature returned to normal and has remained stable. Her latest blood test shows that white blood cells are still high, indicating her body is actively fighting the infections in her leg and uterus.

There is some progress: her anemia is improving, with her red blood cell percentage now at 20% (previously 22.34%, normal is around 37–55%). Her platelet count has also increased slightly but remains far below the safe range for surgery.

Since surgery with these values would still be very risky, the vet recommends waiting a bit longer to make the amputation safer for Casey.

She is eating, receiving her daily medications and IV fluids, and her bandages are changed regularly. She is safe and receiving the care she needs while we continue working to get her strong enough for surgery.


Understanding Casey’s Blood Values

For those without a medical background, here is what these values mean and why surgery is postponed for now:

Why waiting is necessary

White blood cells are high because her body is fighting severe infections in her leg and uterus. The red blood cells and hemoglobin, which carry oxygen in the body, are low, indicating anemia. This makes Casey weak and makes surgery risky. Her platelet count, which helps the blood to clot, is also too low, creating a high risk of severe bleeding if surgery is performed now.

Waiting allows her body to stabilize, reduces surgical risk, and increases her chances of recovery after the amputation.


Casey continues to receive daily care, medications, and supportive treatment to prepare her for surgery when it is safe. She is showing strength and will continue to be monitored closely.

If you wish to support Casey’s treatment and future surgery, any donations are appreciated, and sharing her story also helps.

What This Means for Casey

  • Infection Management: Her white blood cell count is still high, but we are seeing an improving trend alongside her antibiotic treatment.

  • Anemia: She remains mildly anemic, but parameters are better than before, showing her body is working to heal.

  • Clotting & Healing: Platelets are within a good range, giving us confidence in surgical readiness.

Surgery Plan Update We are planning Casey’s amputation for tomorrow. After discussing with the vet, we decided it is best to cut without leaving the femur to allow the cleanest possible healing and to prepare her well for a future prosthetic if she needs one.

Casey remains bright, stable, and is showing us how strong and adaptable she is during this process. We will continue to update you as she goes through surgery and enters the next stage of her healing journey.
