I ran a team of dogs on and off leash...mine were trained ...they did not walk in front of me and they sure didn't walk by my side...they followed - I lead.....I will try and find pictures of my dogs working...
Some were used in film work, others were show dogs...ALL were used to catch and carry rabbits and game birds...2 were trained to go on Hare and small deer...
I always spoke in a calm quiet voice, never had need to shout at them, I had a way of whistling them to STOP when at distance... I used it to make them break off an attack on a rabbit or game bird...
The dogs I had at at that time?
2 Jack Russels (short leg), 4 Whippets, 3 Lurchers, a German Sheppard and a Chinese Crested...Apart from one terrier and the Whippets all the rest were rescues.....most were badly treated and/or half starved...
ALL were trained by me to work for me, I DO NOT agree with letting dogs roam around loose, I DO agree with leash laws, and I advocate good quality training of the OWNERS of dogs...(The dogs are easy to train-its the owners that are impossible to train!!!)
