i taught my dog "don't snatch". with my dog sitting in front
of me i would offer him a treat. i took my left hand and placed it
on his chest as a method to hold him back. i offered the treat.
when he jumped forward for it i held him back with my left
hand and said "don't snatch". i did this all of the time. it was
a part of training. sometimes i held the treat in front of him
close to his mouth. i slowly increased the time before i gave
him the treat . once he caught on it didn't matter if it was
a biscuit, fresh meat, chicken, etc he didn't snatch the treat.
train, train, train. if you don't them doing it train them not to do it.
no matter what it is.
