I agree with god father in the fact that every greyhounds needs are going to be slightly individual.
If you are giving ironcyclen then your chances of overdoing the iron levels are seriously reduced as naturally your dog should pass through any excess minerals (eg iron) when enough has been absorbed.
As for not finishing off races well that is more likely to be a symptom of iron levels being too low than too high.

If you really want to know your dogs levels, proper blood analysis is the only way to do it.

where abouts in adelaide are you NF??

hope that helps, if you want more in depth information ill quiz some more people about it, just let me know.

Cheers
