The first indication I have is that the bitch is more clingy ;-) My bitch is due in about 10 days and she went off food for a few days at about 3 weeks, being sick a few times at this time too. She has also been less energetic, not wanted to run and play with the other dogs. Not her usual behaviour :-)
If she was only mated mid May then there won't be any signs yet, it is far too early. Except perhaps the clinginess, but a bitch can be clingy just after a season anyway. Early morning sickness, and a bitch off her food in the morning, are usually the first signs I've had. However, as already said, this could also be signs of a phantom.

Thanks all. I was just a bit curious and bored:)
Dont know the exacts dates she was mated, just that it was twice and was successful, which I assume means a tie was achieved. The breeder is experienced and the mum to be is on her fifth and last litter so I guess she recognises her dogs signs from previous occasion. Still keeping fingers crossed that I will have a pup in September, plenty of things to go wrong in the meantime.
