Some people feel like they're giving up if they're tempted to use dog training aids. Some think "if you need to use a stop pulling harness then the dog's won!". Please please don't think like that. Expert trainers and behaviourists have invested lots of time and effort (and had fun no doubt) inventing new things to help to make the life of the pet owner easier. Here's the thing though. Preventing a problem happening in the first place it the best way to be able to teach something. You're then not fighting against bad habits. If the bad habits have already formed then again, you don't want to be fighting a losing battle. So, using a training aid like a harness to stop pulling or a long training line to prevent your dog running off whilst recall training, is the intelligent, sensible approach. And then, using clicker training then helps to really accelerate the dogs learning process.
