Aluminium Snap Hook Locking — Lead Upgrade — a premium hardware upgrade for dogs who need that extra level of security. This aluminium snap hook with bayonet locking is available exclusively as a lead upgrade from Dottie's Pet Boutique, available in the UK to our exacting standards.
Crafted from aerospace-grade aluminium with an impressive 400kg breaking load, this carabiner-style hook prevents accidental opening — making it an excellent choice for strong or powerful dogs. Despite its incredible strength, it's remarkably lightweight, so it won't weigh your lead down. It fits leads in 19mm and 25mm widths, with a 20mm inside eye diameter for a secure, snug connection.
Upgrade your lead's clip and walk with total confidence, knowing the hardware is as tough as your dog.
