All dogs can benefit from some kind of training. There are a welth of excellent resources on the internet to help you train your pet. Some of the sites we like are:
The Dog Whisperer - all inclusive dog care website.
RSCPA Austraila - The dogs down under get good training too!
Service Dogs - Some short, interesting videos about the unique world of service dogs. A highlight is the dog who manages to pick up dollars, and then dimes for its trainer.
