That is great advice, thank you so much. I particularly like the idea of peanut butter in a Kong maybe, she will love that I am sure, Also I think the main thing we are doing is not denying her play when she bites as you have suggested, I will certainly try this.
Thank you so much you have been a great help, I will rate accordingly.
ps Possibly too cheeky to ask so please feel free to ignore this bit, but have you found being an expert works well, I should imagine it can be easy for people to not pay so you must be working on faith and trust a lot? I am a coach and wonder whether my career coaching would work in this context. :)
