Dog Prong Collar, Nickel-Free Curogan Training Collar for Dogs Prone to Fur Discoloration or Skin Irritation

This dog prong collar is made from nickel-free Curogan for leash training and is especially suited to dogs whose fur can stain or discolor after contact with some metals.

Curogan is a high-copper copper-tin alloy containing additives that strengthen the material. Its nickel-free composition can be safer for dogs affected by skin irritation or allergies.

Although Curogan generally helps prevent discoloration in fair-haired dogs, a small proportion of dogs—less than 10%—may still experience discoloration.

Key Features

• Creates an active correction by tightening and applying pressure when the dog pulls.
• Releases the applied pressure immediately after the dog yields to the leash or stops pulling.
• Nickel-free Curogan construction is suitable for dogs that react poorly to some metal collars.
• Copper-tin alloy combines a high copper content with strengthening additives.
• Made in Germany to Sprenger quality standards.
