I did try the PDSA but they only provide health care, not routine vaccinations or neutering.
I've left a message at the RSPCA today.
She has found Dad's pedigree, I'm trying to get her to scan it as I'd like to know where he originated from, maybe if his parents came from good breeders it might be easier to find good homes. If she manages to scan it I will post the details on here.
Thanks for offers of foster care, there are at least 4 foster homes available now.
