Greyhound System : does it still work ?

[Geraldo]

Not sure if this is the correct place for this thread, but.... Many, many years ago, I was told that a good system for occasional visits to a dog track was as follows: 1. Back the dog whose price shortens the most. 2. If no prices shorten, back the favourite. 3. Level stakes only, no chasing losses. My occasional visits have long since gone as my nearest track is now about 30 miles away. However I watch occasional meetings on Sky and have used this system with some success this year, although it is a hassle to get the bets on at the last minute. Clearly the system follows the money and I'd be interested to know if anyone else has a similar approach and what success they have..
