Aoife off again

I gave aoife her final gallop before her intended race tonight on tuesday last and sure enough she came off lame AGAIN!! i had her up to the vet yesterday and his advice is to not run her its a real pain in the ass but its the one part of dog racing that does my head in!
anyways she is on the easy list again for another 3 weeks and hopefully i will get her back again its very frustrating and im seriously thinking of retiring her to the breeding paddock at this stage of the game
