Choke Collars

When the leash is tugged, it tightens around your German shepherd’s neck, gaining his attention and then falling loose. If left on an unattended dog, a choke collar can be hazardous. Only use prong or pinch collars under the supervision of a trainer.


If your German shepherd has a respiratory or throat ailment that makes wearing a traditional collar challenging, purchasing a harness is an alternative to consider. Keep in mind that harnesses were created to increase the pulling power of working dogs. Walking a mighty German Shepherd implies you’ll have less control. A No-Pull Harness, which applies mild pressure to the chest and prevents tugging, is another option.

Different Collar Materials for German Shepherds

Collars Made of Leather

Leather collars are a classic, high-quality option for your German shepherd. Genuine leather is considered a natural material that breathes better than nylon, making leather ideal for sensitive skin or allergic dogs.

Leather is long-lasting and easy to clean. Although you’ll pay more upfront, you’ll probably spend less on collar replacements in the long run. Leather dog collars are also popular among owners because of their classic appearance.

Collars Made of Nylon

Chain slip collars can only be used with caution and should never be put on your dog unattended since they can strangle him.

Collars Made of Synthetic Leather

Faux leather, sometimes known as Pleather, is a low-cost material used to manufacture fashionable and economical dog collars and leashes. While trendy and inexpensive, Faux leather collars will not last long and will begin to wear out quickly.
