this is what the trainer said bout biting who came to me for half an hour
" With regard to the nipping, Chloe is giving you a completely natural response to your yelping and saying "no!", that is, she doesn't understand. In the litter her mother and siblings would have nipped her harder to stop her behaviour, if she persisted then the response would have been firmer until she stopped nipping them. Of course, she would have done the same to them when they nipped her, hence the hierarchy develops within the litter. So, I would suggest you use the slip lead and when she is shaping up to bite you can correct her by jerking the lead. You will be able to judge the extent of the correction necessary simply by observing her behaviour. One correction is usually necessary for the puppy to think that other things are more interesting, but if she comes back for more, then the correction needs to be a little firmer. The biting has to stop now or it will continue as she grows and becomes stronger."
So she is implying that a fim 'no' is no good- but I would have to have the slip lead on morning noon and night - has anyone else gone down that route re training the dog to stop biting?
