Best i've found
Bought the Julius k9 power harness for my big lab/retriever before,and back to buy another.(I covered the previous one with cement whilst gardening, no problem with harness) the only problem I did have with it was slight rubbing under the leg (arm-pit) due to my dog being a heavy puller. Little bit of Vaseline now and again will sort it. If you get the correct size, your dog will not escape from it. Its solid and apart from the armpit issue, it seems comfortable. It also looks a lot better than the pics on the site make it look. Best harness I've ever found, if it wasn't, I wouldn't buy a second one. I highly recommend if you have a big dog that likes to pull.
