Why can't dogs have garlic? - in detail
Garlic contains thiosulfate, which is toxic to dogs. When ingested, thiosulfate is converted into various sulfur-containing compounds, including thiosulphates and disulfides. These compounds can damage red blood cells, leading to anemia. Additionally, garlic can cause gastrointestinal upset, including vomiting and diarrhea. In severe cases, consumption of garlic by dogs can result in organ damage, such as liver failure or kidney damage. The toxic effects of garlic on dogs are well-documented, and it is recommended to avoid feeding garlic to dogs entirely.
