I am a professional dog trainer with three shelties,
www.justineleo.net
I spent the first 7 weeks training them to control the bite/prey impluse, then the stupid chicken ran up to my big sheltie"terror of sheep" stuck its wing in his mouth and screamed.
Ivan did not rip the wing off. Good dog.
later another pecked at a bone bewtween his paws, she got a fast , air snap , no contact.
training is the key.!!!!
love my shelties and they loved helping me,(or trying to) put them in the pen for the night, highlight of their day.
all dogs need training to control the prey /bite drive!!!
one of my shelties couldn't care less, he just runs at them once a week for fun, barking.
but boy I train and train ,
I use lots of good dog, leave it cookies. when Ivan did not murder the chicken , I rushed in the house and rewarded the self contol.
Punishemnet does not work, for long term behavior control, it has its place in the training regieme. but not as a first choice.
Positive training got me impulse control, not punishment!!!
Ivan guards the house and yard, now the chicks are part of the yard, like our cats, so they fall under his work load.
Not all shelties are like this, sigh , Ivan will be very hard to replace. I wll call his home kennel and pray the bloodline is still strong.
