You will get all sorts of different answers, but the easiest way to find out is to phone your local council, as each one seems to interpret the new legislation differently.
As regards having a litter, please do think carefully about it, it's something you choose to do and it can and does go wrong quite frequently I'm afraid. Vets fees soon mount up and the worst case scenario is that you could lose her and the pups. I had a horrendous first litter with my bitch some years ago now, and the vets fees from two days alone, for an emergency spay out of hours and treating mum and two pups, was over £2,500.
