Please note that I'm a pet parent sharing my experience with my dog who was diagnosed with hemangiosarcoma. I am not a veterinarian and nothing in this blog post should be used to diagnose your dog. Please use this information to familiarize yourself with this cancer's symptoms and one pet parent's treatment plan. You must work closely with your vet on the care of your dog.

My dog was diagnosed with hemangiosarcoma in August 2020 and this is a detailed account of our first few days, including the change in her diet, the supplements she gets, and our game plan.  We were given three weeks with her and in less than 24 hours we were hopeful that we'd get three more years (or more) with our girl.

When my dog was diagnosed with cancer, I was shattered and confused. We know that our dogs will leave us someday, but we never expect that day to be Today. Something had been off with Sydney for months. I had taken her to the vet repeatedly but the bloodwork and exams always checked out. I thought I was paranoid until I took her to the emergency vet for suspected bloat and learned that she possibly had hemangiosarcoma.

What is Hemangiosarcoma?

“Hemangiosarcoma of the spleen, or spleen cancer in dogs, is a cancer that is diagnosed in many canines every year. It is a cancer made up of the cells that line blood vessels, and therefore can be found in any part of the body. However, the most common sites include the spleen, liver and right auricle of the heart. Approximately 2/3rds of masses in the spleen are malignant and of those, 2/3rds are diagnosed as hemangiosarcomas. Splenic hemangiosarcoma is most often diagnosed in older dogs, with German Shepherds, Labrador Retrievers and Golden Retrievers being the most commonly affected breeds.” ~ AVIM.us

My Dog Has Hemangiosarcoma

A few things to keep in mind if your veterinarian suspects hemangiosarcoma…

1 – The Ultrasound – Sydney had a fast scan ultrasound. This is usually done when a veterinarian is short on time to give a quick diagnosis. A proper ultrasound needs to be scheduled, and a dog needs to be sedated. The issue with the fast scan is that the dog will be standing and may be moving around, so it's challenging to get a clear picture of what's happening. Also, the blood in the stomach obscures the view making it hard to see what's happening clearly.

2 – It's a Cancer Guess, not a Cancer Diagnosis – while a mass can be seen, an ultrasound cannot determine whether or not it's malignant. The spleen needs to be taken out, and a sample needs to be sent to the lab for testing. While a veterinarian can look at symptoms, results of a physical exam, and an ultrasound and come to an educated guess, there is still a chance that this isn't cancer.

3 – Hemangiosarcoma isn't a Death Sentence – this is a sneaky, aggressive cancer that is usually detected in an emergency visit to the vet after a dog collapses. There's little to no pain, and many of the symptoms can easily be explained as something else. We thought Sydney was slowing down due to age, the heat, and her arthritis. The next day, I learned that I got Sydney in early. Although hemangiosarcoma is aggressive, we still have time to change her fate.

If you receive a hemangiosarcoma (spleen cancer) diagnosis and are told that your dog doesn't have long, please get a second opinion. I thought we would have to put my girl down, and less than 24 hours later; we had five more weeks with her. Other dog owners have reported having additional years after an HSA diagnosis.

After a Hemangiosarcoma Diagnosis

I continued feeding Sydney a raw food diet, but I let her eat what she wanted. There are some things to learn about feeding HSA dogs that you can learn by joining a hemangiosarcoma support group. I tried to put Sydney on a Keto diet, but the process of testing her ketones was stressful for both of us. I knew she wasn't going to survive the cancer, so I kept her diet simple.

Supplements Added to Sydney's Diet

There were some supplements that I kept on hand to boost her immune system and to ease the discomfort and other symptoms brought about by a bleeding tumor. My goal was to make her time with me easier. She mostly slept on her bed, which I was okay with, and these supplements helped to give her a few good days.

The Yunnan Baiyao and Hemangiosarcoma formulas were purchased from my veterinarian. You can find Yunnan Baiyao online as well.

Other Tips for Dogs with Hemangiosarcoma

I learned the following tips during the weeks we were caring for Sydney:

  • Don't allow dogs to jump on and off furniture; this could lead to a tumor bleed. Instead, I would encourage Sydney to sleep on the dog bed by joining her there. I lowered my mattress to the floor so she could get on the bed.
  • Avoid golden paste, fatty fish, salmon oil, and other foods that slow or prevent blood clotting. While the risk may be minimal, it's best to learn when giving these foods is safe.

Sydney's diagnosis was confirmed seven days after the initial vet visit, and we learned that she wasn't a candidate for surgery; it wouldn't improve her outcome. Sydney gave us five weeks after her initial diagnosis. When she reached a point where she was having more bad days than good days, it was clear that she was in pain, and her quality of life was declining, Dr. Sara of Compassion 4 Paws came to our home to help Sydney transition. Our hearts are broken, but we take solace in knowing that we fought for and loved her, and she passed in our arms being loved.
