وَإِنْ مَاتَ فِيهَا كَلْبٌ أَوْ شَاةٌ أَوْ آدَمِيٌّ، نُزِحَ جَمِيعُ مَا فِيهَا مِنَ الْمَاءِ
Translation: If a dog, sheep or human being dies in it, all the water in the well is to be drawn.
These are examples of the large-animal category. A fixed 20- or 40-bucket amount no longer governs; the full existing water volume is to be removed.
The discussion concerns purification of the well, not whether an animal may be eaten.
