My only tip for the dogs is bet on the one that just had a shit, its lighter!
on challenge rite now......betting scams..in order to nobble a dog ..give it sausages 5 minutes before a race..lmao
i knew it was a mugs game
I knew a group of guys who bought a dog & thought it was a sure winner - so decided to nobble it for its fiirst race to get better odds in the future. They gave it 2 mutton pies before the race, didn't back it & it romped home

It won a lot of races - but they never got as good odds on it.
