Teaching to talk

I often teach talking in my classes. Talking and speaking (barking) is usually done with capturing the behaviour, so it does depend on the types of vocalisations your dog does. Deska could 'talk like a pirate' but that's not because I taught him those sounds, he would make pirate sounds when he wanted something but didn't want to bark. I also taught 'speak' as a bark - my dogs would bark if I made a raspberry sound so I captured them barking at me making a raspberry sound. However, I think it's really important to teach a dog 'quiet' at the same time and then move to treating the quiet rather than the bark as soon as they work it out, otherwise they may start barking as an offered behaviour for a reward.
