hi all, 
my 15 month old greyhound got a seed or something simular in his side , 
a lump devloped like a small ball ,  
took him to the vet had it operated on couldnt find anything , stitched up sent home , 
a few week later lump up again , back to the vet , yet another operation in the same area , 
result still nothing found , back home he comes , a few weeks later the lump comes back , 
by now i have the shits , with the vet , 
so we are off again , this time to a different vet , one of the best greyhound vets here in vic , 
operation number three , again in roughly in the same area  he is cut open , again nothing found ,  
sent home , each time he has been given anti biotics  etc ,  
some three weeks later the lump is back again , and bursts open , starts to heal , a little ,  
i then give it a course of antirobe tablets , it heals up looks ok now , 
last week it swells up again , and again bursts open with a weeping small hole in his side , 
i just dont know what to do now , i cant spend money on a pup for ever , 
i have tried to help him , but seems like im fighting a loosing battle , 
any more ideas would be appreciated ,
