Training a Labrador should be fun, training a Labrador should be rewarding but training a Labrador should be what both you the owner AND your dog WANT to do.
For that to be the case the whole process needs to be well-planned, structured and patiently implemented.
Do this and you will reap the rich rewards that only owners of well-trained dogs experience.
First, you need to set down a plan of what you want to achieve.
