what is a Halti please, someone mentioned it but no one commented. thanks
We've been looking into these for our Tilley (not a spaniel, but a puller!). The most popular Halti is a headcollar which fits around the dog's muzzle and provides control for the head, not just the body. Our trainer has recommended we use one in conjunction with a harness, as using a headcollar alone on a pup that pulls could seriously damage its neck. We're going to try one soon with a training lead attached to the headcollar and other end of the training lead attached to her normal harness. This supposedly helps to 'balance' the dog when walking, and gives some control of the head as well as the body.
Halti also make a harness which has a front-fastening loop for the lead, rather than rear-fastening. We tried one on Tilley but couldn't get even the smallest size to fit properly: the lead simply pulled the entire harness around to the side.
Our harness of choice at the moment is the Ancol Happy at Heel. It has a unique (as far as we know) side fastening, which brings the lead across the front of the dog's chest and therefore when it pulls, the harness 'guides' it around to face you. It provides by far the most control against Tilley pulling of all the harnesses we've tried so far, and makes it easier to train her, as she is automatically brought around to face us. However, it is not padded and we're keeping a careful eye in case it ends up chafing her and causing discomfort.
