A puppy tests boundaries indoors long before a lead ever goes near a front door - jumping at a visitor, stealing a sock, climbing onto the sofa the moment your back is turned. Grabbing a collar every time teaches something, but not always the lesson you meant.

This is a 2.5 metre line for indoor use, with a smooth end so it doesn't snag or hook on furniture. Worn while you're actively supervising, it lets you step on it or take hold to interrupt jumping up, stealing or climbing on furniture without reaching for the puppy directly.

• 2.5 metre length, designed for indoor use
• Smooth end, so it doesn't snag or hook on furniture
• For supervised use only, never left on an unsupervised puppy
• Interrupts jumping up, stealing and climbing on furniture without a hands-on grab
• Suits a puppy or newly homed dog learning house manners

One thing worth knowing. This line is only safe while you're actively watching the puppy - Coachi's own instruction is that it isn't designed for unsupervised wear, because a trailing line can catch and tangle. Treat it as a tool for sessions you're present for, not something to clip on and forget about.

Who it's for: owners bringing home a new puppy, or a newly acquired dog, who want a hands-off way to interrupt unwanted indoor behaviour rather than grabbing a collar every time.
