I train in the yard with holding blinds. My dog goes very calm from one to another in the yard. Not so at a Hunt Test. Yesterday I heard of a suggestion to put a rope choke lead around the dogs waiste or mid section so to speak. I was told by this person it is very effective in stopping a dog from pulling between holding blinds on the way to the line. I didn't try it, and dont know that I would try that out of fear of hurting the dog seriously like squeezing the stomach or spleen. Does anyone know if this method of correction is safe for the dog and is effective. Obviously one cannot take the dog all the way to the line in this manner.
