In my opinion bedlington cross lurchers can be stubborn, don't give me grief bedlington owners as i love them but all terriers can be stubborn at times, so never give up with it. Their will be times when you wish you had getting a different cross. But with good working parents it shouldn't be too hard to train. You should keep it's training sessions short, 2 or 3 retrieves to start with, same for sit, stay and recall but always give it plenty of praise and it should come good in the end
