‪@KrustynLara‬ In the video there are some sheep sitting comfortably in the polytunnel. the sable dog, Badger, wants to go and look at them. It's on the top of his priority list - go look at the sheep. The unlikely behaviour in this scenario is that he will volunteer to come away from the sheep. The likely behaviour is that he will go and look at them. The looking behaviour can be used to reinforce leaving behaviour. It works by balancing the opportunities to go and carry out the desired behaviour as a result of performing the less desired behaviour. Shuttling backwards and forwards from gate to me and back again results in much less intensity in Badgers need to go look at the sheep. This is because he begins to realise that the opportunity to go back is freely available to him. And as we all know, once something is freely available with no negative consequences to engaging in an activity, well, the shine goes off it a little bit and the need to keep trying subsides a little. "Oh, what looking at sheep? No thanks, that's ok, I can do that anytime" The Premack Principle (David Premack) and the Theory of Deprivation (Allison and Timberlake) are staple parts of training in the herding dog. No shock collars, prong collars are necessary or used in the training of these dogs. The sheep by the way are mine, sorry to say, you can't just rock up and use someone else's sheep this way......... needs a risk assessment to ensure their welfare!
