Absolute waste of time & money
This product is no use for a large strong dog, certainly not a Labrador as pictured! My boy has too strong a chest for this to be any use - maybe on a less muscular dog it would work. I tried the harness, having used the Halti Headcollar in the past because my young dog wouldn't settle to the headcollar but have given up with the harness and am persevering with the trusty headcollar!
