Canine Toxicity
Definition: The adverse physiological effects resulting from the ingestion of substances toxic to Dog. Due to distinct metabolic pathways, many substances safe for humans are lethal to dogs.
Key Toxicants
Xylitol
- Nature: Sugar alcohol found in plants/mushrooms; used as low-calorie sweetener (~40% fewer calories than sucrose).
- Mechanism: Triggers rapid, excessive insulin release in canines.
- Consequence: Severe Hypoglycemia and potential acute Liver Failure.
- Source Context: Discussed in Xylitol: Human Health Benefits and Canine Toxicity (SciShow summary, 2026-05-26).
General Principles
- Dosage Sensitivity: Toxicity often dose-dependent; even small amounts of high-potency toxins (e.g., xylitol) require immediate veterinary intervention.
- Metabolic Variance: Canine metabolism differs significantly from humans regarding alcohol, phenols, and certain carbohydrates.
