There is not a set answer for this question. It will depend on a lot of factors including but not limited to; your dogs personality, their age, the behavioural concerns, the intensity of the unwanted behaviours, how quickly and confidently you pick up the training techniques, how much time you have during the week to dedicate to your dog’s training, how high your expectations are of your dogs behaviour. The best way to think about dog training is the same way you might think about learning any new skill. If you wanted to learn a new language would you have two lessons and then expect to be able to speak and understand French, Chinese etc or what about learning to play the piano, how much support would you need? Both you and your dog are learning to communicate with each other, your dog is learning what behaviours you are expecting from them and what all these new words mean – sit, drop, bed etc. I have a number of programs available with different duration lengths, expected training outcomes and levels of support. Training is for life between you and your dog…how long you need professional assistance for or how much support you want is individual to each human / dog relationship.
