Quick answer
Choose a 5m Flexi lead for everyday walks in busy or narrow areas where you need close control. Pick an 8m Flexi lead for open spaces like parks or trails where your dog can roam farther safely.
Why cord length matters for control and safety
A retractable lead's cord length directly affects how much freedom your dog has and how quickly you can react. A shorter cord keeps your dog closer, which is helpful near roads or in crowded places. A longer cord gives more exploration room but requires you to manage the extra slack and be ready to lock the lead quickly.
Flexi leads use a comfortable short-stroke braking system and a permanent stop feature, so you can lock the cord at any length. That means even an 8m lead can be shortened instantly when needed.
Weight limits: matching the lead to your dog
Flexi leads are rated for specific dog weights. The medium cord models (5m) suit dogs up to 20 kg, while the small cord model (8m) is designed for dogs up to 12 kg. If your dog is heavier than the limit, the braking system may not perform as intended, and the cord could wear faster.
Always check the weight rating before choosing a length. A small dog that loves to run might benefit from the extra 3m of the 8m lead, but only if it stays under 12 kg.
How to choose your Flexi lead cord length
- Your dog's weight: If your dog weighs up to 12 kg, you can choose either the 5m medium cord or the 8m small cord. If your dog weighs 12–20 kg, stick with the 5m medium cord models (e.g., Flexi Black Design or Flexi Classic).
- Walking environment: Use a 5m lead for pavements, busy streets, or narrow trails where you need to keep your dog close. Use an 8m lead for open fields, beaches, or wide park paths where your dog can safely roam farther. If you walk in both types of areas, a 5m lead with the permanent stop feature can be locked shorter for tight spots and released for more freedom.
- Control preference: If you prefer to keep your dog within arm's reach most of the time, a 5m cord gives you less slack to manage. If you want to let your dog sniff and explore without unclipping the lead, an 8m cord offers more range without switching to a long line. The short-stroke braking system works the same on both lengths, so your stopping power doesn't change.
