Depending on the age of the dog and the severity of the problem, most behavior re-training programs take a minimum of between six and eight weeks. Although we have solved many problems (including aggression) over the phone, obviously the training is much more effective in person. Although in many cases we have met with the owners once or twice and seemed to have the problem solved, we want it solved permanently. Our job is to train the owners to be consistent as well as the dog. Depending on our evaluation of the problem, the price of this course would be anywhere from $750.00 to $950.00.
