Grace (SBT) has a rich vocab lol. Woo-woo, grr-grr, moans, groans, squeals. The whole lot. She talks to say good morning, talks when she's excited, talks when she's happy, talks when she's hungry but on the whole she is a happy girl and doesn't backchat too much lol.
Abby (Chi x) talks when tugging (growls), talks when playing the mouthy hands game (can't describe what's going on there), but mostly barks. She is a barker. Even when she is uber tired, she still finds the energy to bark. I just manage it the best I can - I certainly don't allow her to go on too much. She barks when she is playing, when she is attention seeking, telling me something is around, she will answer bark some dogs in the neighbourhood and she does backchat!
