I've bought the prong collar for my 4.5 y.o. Staffordshire walking. I took her some weeks ago and it required force for her to walk on a leash. At first I used a slip but it did not suit her power. She was also not socialized properly that's why she attacked dogs in walking. Then I decided to get a prong collar from you, 'cause the price was the most reasonable and also I could order extra links here at once. It was delivered within 6 days. The prong collar has a lot of benefits, my dog obeys now and I may control it easily when we come up to other dogs. I suppose that we can control her easier in general now with the prong collar help and she becomes more obedient in walking. I recommend it definitely.
