Fine.
I will give you this suggestion. You probably won't use it because, it seems that one minded approaches abound here. No balance. When I wrote be smarter than the dog I wasn't kidding. Set boundaries, use all of the tools that you have at your disposal. Now in order to do this you must understand how dogs communicate. They communicate spatially, audibly, visually, by scent and physically pressures. These are your tools you can use them all or you can fail by not understanding them and using them together. For instance only using force or only using positive reinforcement is unproductive. Boundaries in this case may include when the pup ties to bite in play simply make it unproductive by using physical pressure. Spam folks??? 25 years of selling trained dogs in all arenas for $50,000 a piece, if you can do it be my guest. You can't , otherwise you would be. Maybe asking questions instead of making rude statements would be more productive being that I'm taking the time to see what arenas out there can and will use help for free.
