Consistency in Training

Consistency is key in training!

It's hard work, but as I've said before, you have a dog so by association you are his/her role model and therefore, you are his Pack Leader.
Once you get in to your role, I guarantee you'll find it easy and rewarding beyond belief. And you will also see that there is plenty of time for cuddles, love and affection. Just not during your dog's 'work' hours - not while he's 'on the job'! This is a concept we human-doings must surely understand in relation to our own work lives. In light of professionalism, no matter how much we may like it, we prefer our loved ones do not disturb us or drop in on us during our work day for cuddles or random chatter.
Our 'work' gives us purpose in our lives and this is no different in our canine buddies. Your dog would have a job within his pack in the wild. He might be in charge of digging a hole for the pack to sleep in to keep cool, hunting to keep the pack fed, or watching out for predators. Give your dog a job, train him to do his job and make sure he works hard every day. Then at the end of the day you and he can enjoy the rewards of affection and share in the sense of achievement that comes with having purpose and responsibilities in your life.
