Working With Giant Dog Breeds

It is common practice to use long lines when training dogs. Most trainers will have the standard 20 or 30 foot cotton long line in their training supplies. However, these are not sufficiently strong and easy to use when dealing with very big dogs that are over 120 lbs.: Mastiff, Dogue de Bordeaux, Neapolitan Mastiff, Bullmastiff, Boerboel, Caucasian Ovcharka, St Bernard, etc. I've trained many very big dogs, so for them, I use a horse lunge line. It is easier on the hands and less likely to break if the dog pulls hard. Here is an example of what I have:

A 32 foot/ 10 meter horse lunge line
