Hi All
Sorry took so long to reply, here is the link
http://www.nwlabs.co.uk/newsletter39.htm#Canine%20PregnancyMy vets not very good at palpapating and not good at scans either, each time I go to the vets they say yes I think she's pregnant and it then turns out to be a phanthom. I think the best method like someone said is the waiting game, which is all so frustrating, as you want to get organised. I now have everything for a whelping and no bitches in whelp. :-(
