Sanity Savers for Positive Trainers answers this question so you can stop (mis)behaviour** in it's tracks, without feeling bad or guilty, and instead, you can get on with enjoying your dog.
This little book looks at 3 training tools and how to apply them, using 3 common unwanted behaviours as examples. However, these tools work for any kind of (mis)behaviour**, not just those in the examples.
It also looks at 3 very common, but not obvious, training mistakes that can really scupper your training if you don’t realise they’re happening! They’re so common I don’t think there’s an owner/trainer alive who’s not made them at some point - but that doesn't mean you have too.
