Thanks for the responses everyone!
It just struck me as strange - You seek the advice of veterinary staff as a safety net (lets face it, not everyone has access to the internet or is confident to use it for research, there is so much information out there) but I just couldn't get over the fact that not only was it terrible advice, it was dangerous - Excess Calcium in a growing large breed can cause some pretty major issues with skeletal abnormalities.
I understand that not every diet works for every dog. Some foods don't agree with all dogs - like people, some of us have intolerances and it's not the foods fault, it's that it doesn't suit us.
I chose TOTW from the reviews I've seen on dog forums around the world (understanding the good and the bad of it) and at $20 a week (plus her fresh content food) it's certainly not cheap, but I have fed a dog on a cereal dry diet with tinned food extras in my younger years (before I knew better) and this food is just out of site in comparison. People look at me like I'm crazy when I talk about her food and what my aims are (to understand as much as I can as quick as I can) but when you see 8 year old large breeds that are overweight and can't get around - I see that indeed I'm doing the right thing by not pumping the "rapid puppy growth" food into her - It just does more harm than good.
We already get comments on how lovely she looks, we want to keep it that way!
As she is a fussy eater I've had trouble introducing veggies into her bowl (I'd like to be able to give her a nice varied interesting diet) but I need to do a bit more reading into that part before I try too hard.
