⚠️ Medical disclaimer & important notice
This guide is intended solely for general information on emergency preparedness. It is not a substitute for professional first-aid training or medical advice from qualified personnel.
Act immediately in a medical emergency: always try to call the emergency number 112. You can find a certified first aid course at the German Red Cross (DRK). Last checked: June 2026.
Supermarkets will be empty after a 48-hour power cut – including the pet food shelves.
This affects you and your four-legged friend directly, because in a crisis, hunger quickly turns to sheer panic. Whilst most people think primarily of their own supply of water and light, their most loyal companion is often left defenceless. Your pet cannot help itself during a blackout – it is 100% dependent on your foresight. In this guide, Wolf shows you how to ensure your pet is fully provided for using the tried-and-tested 3-pillar method.
| Pillar | Essential item | Minimum requirements (per pet) | Wolf’s expert tip |
|---|---|---|---|
| 1. Warmth & shelter | Insulation & rest | Blankets / thermal coats | “Reptiles and small animals cool down extremely quickly. Insulate transport boxes!” |
| 2. Water | Fluids | Dog: 1L / Cat: 300ml (daily) | “Make sure you have a water filter. Animals can’t tolerate contaminated water any more than we can.” |
| 3. Food & Storage | Self-sufficient supplies | At least 10 days’ supply of dry food | “Do not leave wet food out in the open. It will spoil in record time without refrigeration.” |
Pillar 1: Warmth & shelter – Stop the psychological stress
Animals experience a power cut completely differently to us. Sirens, sudden darkness and the disruption of their routines put dogs and cats on high alert. If the heating then fails in winter, the cold becomes a deadly danger.
Small rodents, birds and reptiles in particular struggle to cope with sudden drops in temperature. Provide insulated places of refuge. A carrier lined with blankets retains your pet’s body heat far better than an open basket.
Wolf’s rule of conduct: if you stay calm, your pet will stay calm. Stick to your usual feeding times as closely as possible. Use familiar aids such as Thundershirts or calming sprays (e.g. Adaptil for dogs or Feliway for cats) as battery-free stress relievers.
Pillar 2: Water – The unvarnished truth about fluid requirements
The official BBK guideline recommends 2 litres of water per person per day. But have you factored in the extra water for your pets? When not a drop comes out of your taps, every millilitre counts.
A medium-sized dog needs up to 1 litre a day when stressed. Cats manage on 200 to 300 ml. For a safe 10-day scenario, you therefore need at least 10 litres of pure, uncontaminated extra water for a dog in your emergency stockpile.
Pillar 3: Food, Medicines & the ‘Ready’ Principle for Dry Food
An open bowl of wet food becomes a breeding ground for bacteria within a few hours in a flat without air conditioning or heating. That is why the honest recommendation for your emergency supply is: consistently opt for high-quality, dry food in airtight containers.
The situation becomes particularly critical for chronically ill animals. Whether it’s insulin for a cat or heart tablets for a dog: pharmacies and vets will be closed for days during a widespread blackout. A solid supply lasting at least two weeks is not a luxury here, but a lifeline.
The blackout pet bag: your 10-day checklist
- Dry food for at least 10 days (vacuum-packed)
- Extra drinking water (calculated for 10 days per pet)
- Foldable food and water bowls (space-saving)
- Sturdy carrier, as well as escape-proof harness and lead
- Essential medication (at least a 14-day supply)
- Waterproof document folder (vaccination certificate, microchip number, emergency vet contact details)
- Recent photo of the animal (printed copy + saved offline on your smartphone)
- First-aid kit specifically for animals (including self-adhesive bandages and tick tweezers)
- Hygiene supplies (bin bags, wet wipes, biodegradable cat litter)
- Familiar blanket or toy (important for the comforting familiar scent)
Conclusion: Act before the crisis dictates the decision
The first 72 hours of a widespread blackout determine whether there is safety or sheer chaos. Your pet cannot make provisions – but you can. If you sit back and do nothing, you risk the health of your most loyal companion in an emergency.
You now have three options:
1. You leave this page and hope that an emergency never occurs.
2. You buy some random accessories without preparation, which will fail in an emergency.
3. You take the only rational step: ensure comprehensive protection for yourself and your entire family.
