Chewy has started to get a little nippy too... he is a year and a half. he will decide every so oftn he doesn't like someone!

he is either home or in the car when he does this.... The book the loved dog says to give the person they dont like a treat to WIN THEM OVER... i thought it sounded crazy and it worked like a charm!!!
Also Chewy has always tried to bully my son (Mike is 23 years old and was in college last year so chewy didn't see much of him) he was very nippy not long ago with Mike. So Mike stuck him in the bathroom for like 3 min...went to let him out in a sweet voice...bit again!!! Back to the bathroom... for about 4 tries. Finally when Mike opened the door...out came a very humbly loveable chewy!!! It took a few tries but he realized Mike was no push over and he gave kisses.
