Knowledge, dont know about horses but i have had inside knowledge[ no pun intended] about a few dog fixes a few years and they were VERY profitable, but on the other side of it, ********ed me off one night at maitland dogs, i had a dog in a race and it had NO hope of winning but was a quick beginner and would have led [box 5,and always led ]walked out of the boxes and was all over the track which was strange for him, found out later that the pro punters had taken 3 dogs in trifectas and collected,a trainer/punter that i knew,that was in the know told me as i was going home that he was GOT AT and i showed him that the dog could not open his eyes,the **************s had sprayed something in its eyes whilst in the kennels.
