Best place to purchase a custom made weightpull harness is from windchill in Victoria,i think www.windchill.com.au will get you there or go to the Vic Alaskan malamute club site.I have had several harnessses made and never had a problem (dont be put off by what at first seem to be complicated measurements).I have competed my American Bulldogs at a couple of the comps put on by the Vic malamute club,they are extremely well organized,well run and very enjoyable to participate in.Last time i went i had one of the biggest highs i have experienced with my dogs when my Lizzy won most weight pulled on the day.
