ULTRA-PLUS Training Collar with Center Plate, Assembly Chain, and Swivel Ring - Stainless Steel Black

I have a Dogo Argentino and was useing a 3.0 prong collar it just was not doing the job. Now that I ordered the 4.0 my boy is perfect on his walks. Once he pulls the slightest bit he automatically corrects and comes into a heel I do not even give pressure it's his own pulling that corrects him. I was told from K9 trainers to use a 3.0 and it was just too small for this dog. He is now a year and 4 months old and it's the one tool that really keeps him popping without me doing a thing. Sizing the prong collar properly is really important don't take it lightly it's the matter of having a great behave dog compared to one that behaves once in awhile. My dog looks forward to putting it on to go out for walks. Win,win.

I have a 100lb Great Pyrenees that protects my sheep and is a big puller whenever I take him anywhere on a leash. Was told about Hem Springer and their prong collars. Decided to get one. Got the 4mm (biggest). In one 5 minute training session to get him used to it, he some how magically turned into a completely different dog! I did watch a few YouTube videos to ensure I was putting the collar on correctly and how to train him with the prong collar. The difference is night and day. Hen Springer just got a customer for life. Its rugged, durable, quality, craftsmanship, ease of use, etc all get 5 stars. These folks know what they are doing! Thanks for making such an astounding product!!

Great stuff, top of the line.

Great trainer
