Hi All, just stumbled across this site and seems to have a lot of great information. I currently live with six dogs - who all have special/different training needs. My oldest is a Boston Terrier whom I adopted last year at the age of 14; My youngest is an almost one year old lab-mix that I raised from the age of 5 weeks. He was left at a shelter as an orphan puppy. Two of my dogs need more mental stimulation - so I'm looking foward to working with them some more other than with the basic sit, stay, down and wait.
