after searching previous post on scans - when is the earlist a bitch can be scanned - either vet or sheep scanner. and what days are the best for scanning thanks.

28 days seems to be the best

I had a bitch scanned by someone who did scans full time for various diagnostic reasons and he did it at 25 days and pronounced a good size litter (she went on to have 9 the largest litter I have had), most others have wanted to do it at 28, days at the earliest and nearer 30.

Mine does it at 30 days after second mating and has been dead on with the number.
