How vets treat it

Seek immediate veterinary care for decontamination, monitoring of red blood cell counts, and supportive care such as IV fluids or blood transfusions if anemia is severe.

Why it's dangerous

Garlic causes oxidative damage to red blood cells, leading to their rupture and subsequent anemia. It is significantly more potent than other Allium species like onions.
