I may not be able to write in English everything what I mean .. And those are just my opinion.
At least I do not know the correct terminology, so it may be you do not understand what I mean
But I think he uses too much stimulation .. such as a whip.
So do your dog is acting without any stimulation? If the dog is often given stimulation that get them to bite and to act. Then the dog will never learn self-active.
For example, many of which are the dogs do not, in Itself of active but rather they havebeen impregnated with a variety of stimulation.
So if the decoy is sitting in a chair in the middle of the field, and he does not give any stimulation, and facing away from the dog.
So many times the dog does not even bite.
And when your dog bites the sleeve, the decoy should calm the situation and get the dog to channel the power of self-biting.
Now, in that video the dog just rips the sleeve and the decoy does not intervene.
Your dog does not bite a man, only the sleeve.
So, like in that video, 3.05 is indicated as it's not a interested in decoy.
It is a objectified only to to your sleeve. Although it should be to guard a man.
But these are matters which fall within your decoy. Not you.. And just I say this is only my opinion, not everybody.
Anyway as I say it was really nice to see working bulldog video
Keep up working Noel
