Doggie system that can't loose.

Don't bet the first race.
Whatever number wins back that number in the second race.
If it wins stop betting.
If it looses in race 3 back the winning numbers in race 1 and 2 to make a profit.
and so on until you back a winner.

the principle is that on a 10 race programme a box draw must win at least twice.
The earlier the more profit.
Only works on fixed odds of course.

Sound in theory
In practice.................
