I HAVE BEEN USING JULIUS-K9® IDC® POWER HARNESSES FOR MY TEAM OF PERFORMANCE DOGS...
since October 2017, and I couldn't be happier with them. They have a range of sizes to suit whatever size and shape your dog is, and ensure a very snug and secure, yet comfortable fit. They are escape proof, but ridiculously easy to put on and take off, for the level of security they offer once they're on. I also like the fact you don't have to pick dogs' legs up and put them through a section anywhere.
I have used many different types of harnesses over the years, that are either easy to escape from, difficult to put on or take off, restrict the dog's movement, or just don't sit nicely. IDC® Powerharnesses are just awesome, I use them for agility shows, general walks, and during our trick shows. The dogs are more than happy to wear them, and I like the reflective trim around them for the added safety benefit at night. The fact you can personalize them with your dog's name as well, is just another cool feature that they offer!
They haven't missed a single thing with their design, you can secure either the handle and the D ring, or one or the other down while the dog is off lead, for safety purposes. They are designed so the dog can roll etc and there is no protruding hardwear which could hurt him or be uncomfortable.
All in all, I am absolutely wrapt in the Powerharness, and my dogs are as well. A fantastic product I will never be without again!
