Herm Sprenger - Chrome Plated Steel Additional Prong Links for Herm Sprenger Ultra-Plus Dog Training Collar - for Small Medium Large Dogs - Made in Germany (2.25 mm)

I purchased the original collar from a trainer and my dog filled out so I needed extenders. These worked perfectly. Easy to put on with pliers. Do not fall off and fit him perfectly now. Great value and I didn't have to buy a new expensive collar.

I needed an extension for my puppy’s first training collar but didn’t want to buy an entirely new collar. I actually prefer the smaller collar which has smaller links and more prongs. These prongs fit right into her existing collar and made it so it fits properly since she has grown. The quality of metal seems to be the same as the original, the strength it takes to pinch to remove the links is about the same as well. They are not more flimsy. It is easy to put on and take off. These collars are VERY effective in teaching my strong and growing Lab pups how to properly be sensitive and not just muscle through their leash time. 10/10 would recommend these collars and the Herm Sprenger brand.

Fit perfectly. Herm Sprenger is the gold standard.

I didn’t end up using these particular ones because I ordered the wrong size but the products from this company work wonders for my big dogs. My young kids can walk my big dogs with no issues. These are super easy to use, just add the link to the collar as you would normally fasten the collar. This stopped both of my dogs from pulling while on walks. Much cheaper than buying an entirely new collar just to increase the size.

Worked great with her collar

Excellent add on links to collar, same rounded prongs for comfort and same quality as collar, easy to add on and adjust

Fits right. Prongs seem solid. Easy to install. Works good.

Fits the collar well

They fit great on the collar. Not like some of the knockoffs available here on Amazon. highly recommend
