Brain tumors in dogs can progress very quickly, often showing significant, life-altering symptoms within days to weeks, though some slower-growing tumors may develop over several months. While median survival times without treatment are often only a few months, some cases can become critical within just a few weeks of the first seizure.

What is the timeline of a dog brain tumor?
