We adopted a dog last January who was less than a year old at the time. Marlin is pretty well trained, listens pretty well, is very smart, etc etc. I know a fair amount about basic training methods and also know that most feedback for dogs needs to occur within as little as a second and a half after behavior. Marlin is a great dog when we're looking. However, when we're not around, he has a habit of deciding that is a good time to break the rules. If there is any food item within paws reach, he'll get it. Even non-food items (for example a non descript engagement ring box or makeup pads) are at risk if we've slacked at all with exercise. I am mostly concerned with the food-items. Since positive and/or negative feedback needs to occur at the time of the infraction, what techniques are available when the problems occur 100% of the time when you are not around. Same problem with digging in the garden. He knows the rules, but turn your back for even a few hours and off he goes.
