Our 8 month old German Shepherd 'Bentley' is a BEAUTIFUL dog....loyal, playful, intelligent and friendly, in fact he's TOO friendly. Where I live in Philippines it pays for your dog to be seen as a GUARD dog, not to be feared, but certainly not too approachable! Now I obviously don't want him to start biting everyone he sees, but it is HUGELY beneficial that other non-family people realise that he is our PROTECTOR. Is there a specific training course for this?
