this is how i see it, the dog in question 13/14month old, has been lamping a few times and has ran on the lamp before and cought rabbits, but just resently has not been, at first the dog seem to run the beam after seeing the rabbit the rabbit would run then the dog would turn off if and run on an angle back, then slowly seemed to get less and less were now hes running 10ft say down the beam and turning back, on rabbits that are visable, the dog has been out during the day and done ok but as its been mentiond above i think its nothing to do with the day time outings, the lamp has been on say 10
