The Death Cap “Honeymoon Phase”
The death cap is particularly dangerous because of a deceptive recovery period:
- Phase 1 (6–12 hours): Severe vomiting and diarrhoea
- Phase 2 (12–24 hours): Apparent recovery — dog seems better (this is the “honeymoon phase”)
- Phase 3 (24–72 hours): Rapid liver and kidney failure — often fatal
Never assume your dog is fine just because symptoms temporarily improve.
What to Do If Your Dog Eats a Wild Mushroom
- Stay calm but act immediately
- Take a photo of the mushroom (or collect a sample wrapped in paper, not plastic)
- Note the location — grass? woodland? tree stump?
- Contact your vet immediately — time is critical
- Do NOT wait for symptoms — some toxins have delayed effects
