If you’ve followed Cat’s story, you know hemangiosarcoma (HSA) is one of the most aggressive and devastating cancers in dogs. It often strikes without warning, spreads quickly, and leaves families reeling. While it affects many breeds, German Shepherd Dogs & Golden Retrievers are especially at risk — with recent studies showing that nearly half of all cancer deaths in these breeds are from HSA.

But here’s the question researchers are finally beginning to ask: Why are so many dogs developing this disease?

In an upcoming webinar hosted by the Canine Cancer Alliance, Dr. Catherine Wise, a research scientist at Duke University, will share emerging findings on a potential link between environmentally common chemical exposure and an increased risk of canine cancers and specifically hemangiosarcoma.

Dr. Wise’s team — including Prof. Heather Stapleton — is conducting the first targeted study measuring how everyday environmental exposures (from flame retardants, lawn treatments, plastics, air pollution & the like) may be connected to this cancer.

It’s groundbreaking work — and a conversation every dog parent should hear.

…For our part, I wish we’d known so much sooner.
