My 4 month old westie is getting very cheeky now, if she cant get what she wants she grabs your feet, trousers , hands , its funny at this age , but i know when older it can become a problem, any advice how to deal with it please ....

Being honest I have always found if you stop them right in their tracks , give them a firm telling no with a firm voice they soon get the idea.  Don't allow it once or twice and then when you have had enough stop them. Stop them first time they get the message quicker that it is wrong.

Good luck

Pam.
