therein lies the rub... it's not a matter of understanding form "well", it's if you understand the form better than the market.
I am not into the dogs, but by reputation, I would be wary. The prize money is a pittance for most dogs races, so from what I have heard the only money to be made for trainers is by betting. So, there is an incentive for trainers to have their dogs run poorly for a few races to drive up the odds for a future gamble. I have heard a lot of disquieting stuff about the prevalence of doping in dog racing - trainers giving dogs tranquilizers etc (the traditional method was supposedly sponge cake soaked in lemonade to bloat them!). My family are more into horses and I know these days that my Dad tends to stick to high grade races - as they have the most trustworthy form-lines (although, the penalty is that the information is more widely known so it is harder to gain an edge on the market).
