If you train your dog with pinch collar you may need additional links. Neck Tech Collars are of different sizes. They depend on the collar length and the width of the collar.

 You will need extra link in cases when:

• you are an owner of a growing puppy
  
• or if the first measurements were incorrect. 

Don't be upset you can easily settle this problem by purchasing this Neck tech extra link made of Stainless Steel. If your dog's neck circumference is more then 24 inch (60 cm), you can order an additional link, that will add 1 1/4 inch (3 cm) to the total collar length. You can add or remove links to make collar smaller or bigger so it fits your dog perfectly.
Please, be advised that you will need needle nose pliers to perform this action.



These extra links are made of Stainless Steel. You may wonder why Stainless steel of all other alloys were chosen for this purpose. It is easily explained because this alloy has many advantages over the normal steel especially in coastal areas where steel chains will become slightly rusty already in the shops. There are also a large number of dogs which are crazy for water. Furthermore there are dog groups which are permanently in contact with wetness, e.g. the hunting dogs and the dogs working for the police. Chains made of normal steel will become dull after contact with wetness. Especially salt water will roughen the plating layer with the result that the chain gets rusty. This cannot happen to stainless steel.
Stainless steels have a higher resistance to oxidation (rust) and corrosion in many natural and man-made environments; however, it is important to select the correct type of stainless steel for the use. Herm Sprenger designers and engineering technicals did their best to choose the right type of Stainless steel that will not stain, corrode, or rust as ordinary steel and you can see it for youself when you have stainless steel pinch collar with additional links of the same material. It will serve you for a lifespan.
Stainless steel is, above all, a very practical material, however, this material is both aesthetically beautiful and noble. It is shiny as a silver and your dog will look gorgeous wearing collars made of stainless steel.
