Nothing is perfect in life John F .....
Sometimes scientists get caught up in the process and need to see a clear cut result that 2 plus 2 is four. But Nature sometimes says that 2 plus 2 can actually be four and a half, if you get my drift.
So it is with the dogs.
The dogs don't lie about the odour. The complicated bit comes when the handler has to decide which hive the dog indicated on, and that can have variables that are governed by wind, temperature and lie of the land.
So out in the bee yard in the still of a full moon evening the dogs are saying " Yes Boss, this smell is really ripe" ... and then it comes down to the skill of the handler to read the dog and ask it again ..... OK ..... where's the smell originating from , and are you sure.
I think I have often said, they are not the B and end all of AFB eradication, but they are an incredibly usefull tool is rapidly ascertaining if the operation has an issue, and are very good at picking up on pre clinical infections.
And this is where Beekeepers get a bit a sceptic, because the dog indicates and the bee keeper looks and finds nothing.
But if the bee keeper put that hive to one side and waited twelve months .... then I'd put a box of Speights on it that he would find something.
Don't get me wrong ..... science has a lot to offer society, but sometimes one has to go with the heart ..... and we have learnt that our dogs have a valuable contribution to make in reducing the incidence of AFB ..... if we want to.
My heart also tells me that it will be quite a few years before the Agency lets the dog lick its nose.
