Its a disease passed on from ticks - there are three main diseases - lymes diseas, borreliosis and bartonelas (see bada.co.uk website for details).
They can be transmitted to pets and humans quite easily and are usually in the hosts system indefinately.
I know two gamekeepers with lymes disease and there fecked, and my springer had bartonellas - cost me two grand at the age of 17. She is cured now (fingers crossed) as i caught it in enough time - its fascinating that most vets know NOTHING about it, i had to get reverred to Glasgow vet school, hence the shit price.
Be very carefull wh
