I wanted to share this out of love and awareness.
We recently lost our Great Dane, Ace, unexpectedly at 9½ years old to a cancer of the spleen (hemangiosarcoma). We had absolutely no idea it was there. He had regular yearly exams and bloodwork, and nothing ever showed up.
Unfortunately, this type of cancer can grow silently for months without symptoms. In Ace’s case, the first sign was when his spleen ruptured, and by then the cancer had already spread to his liver. It was too late to save him.
I’m sharing this because we wish we had known this cancer even existed. If awareness helps even one dog be diagnosed earlier, then Ace’s story matters. For higher-risk breeds like Great Danes, some owners choose additional diagnostics later in life, such as abdominal ultrasounds, since routine bloodwork often does not detect this disease.
There is no way to predict or prevent it, but knowing the signs and options may help others make informed decisions as their dogs age.
