I have both dog and bitch, hopefully mated them a few weeks ago, as far as i know there wasnt a tie.  My bitches mannerisms seemed to have changed shes sleeping alot and not as playful as it was always her that wanted to play. I phoned my vets but said to wait until shes aleast 4-5weeks for an ultrasound scan. the waiting is killing me.As they are both at home with me its hard to say if and what date she may have caught on. But he kept trying for about a week, so if she is pregnant she is either in her3rd or 4th week now. She has also been sick a couple of mornings this week. But it might be just wishful thinking on my part.Her nipples are quite large but i cant remember how big they were befor. Pls could anyone help or if there are any Golden ret. breeders out there that could help.
