thanks for all your suggestions and advice! Just letting you know that things are on the improve finally! I read somewhere about spraying your pup with water might help, and guess what .. it worked! I started doing this a week ago and he has calmed down considerablly.. still jumps and bites but is much more gentler with me... in fact we have lots of cuddle time now, and if he bites i say no... and make the noise of the spray bottle and he backs off and starts licking! so then i say "good boy" Im so suprised that something as simple as this has worked when every other method I was trying was making him more aggresive. ahhh its a big relief.
