How It Works
This general toxicity guide covers the most commonly ingested dangerous household substances. Each substance has a known toxicity profile and recommended action threshold. For grape, xylitol, ibuprofen, and paracetamol — any amount is treated as a potential emergency. For onions and garlic, the dose matters but cumulative exposure from regular amounts is also dangerous.
Veterinary Research
Every formula is derived from peer-reviewed veterinary studies and clinical guidelines, not guesswork or generic rules.
