Dog Chocolate Calculator UK
Enter details below to assess chocolate risk for your dog.
How It Works
Chocolate holds theobromine, toxic to dogs as they metabolise it slowly. This calculator multiplies chocolate amount by type’s theobromine concentration, divides by dog weight for mg/kg dose, then checks against levels: below 20 mg/kg counts safe, 20-40 mg/kg needs watching, 40-60 mg/kg demands prompt vet visit, above 60 mg/kg risks fits or worse.
Signs to Watch
- Restlessness or rapid breathing
- Vomiting or loose stools
- Excess thirst or pacing
- Shaking, fits or collapse
Next Steps by Risk
- Safe: Keep observing for 24 hours.
- Monitor: Watch closely; ring vet if signs appear.
- Urgent: Contact vet straight away; take packaging.
- Emergency: Go to nearest vet clinic now.
Common Myths Cleared
- Baking chocolate harms most due to high cocoa.
- White chocolate rarely poisons but upsets stomachs from fat.
- Small bites build up; repeat exposure worsens effects.
- Never force vomiting at home – it risks aspiration or oesophagus damage.
Prevention Tips
- Store treats high up or locked.
- Watch at holidays like Easter or Christmas.
- Check post for gifts.
- Skip cocoa mulch in gardens.
