I have just phoned the vets and explained about the continued diarrhoea.
They said that there isn't much point in seeing her again

but I could have some more pro kolin... I also asked whether changing her food could help - they said it was worth a try but had to be done very gradually otherwise it could give her an upset stomach...( strange that as she already has diarrhoea! )
I might change my vets, but now i'm not sure what to do for the best.
Do I go with the gradual change to meat? Or get her checked again by a different vet?
I don't want to wait if it's something serious.
