Just wondering is it true that bitches think they are pregnant just because they have been mated wheather they are or not?

and how long after is it normal to start showing signs such as sleeping more and sickness, I understand it is roughly 2 wks but my bitch is 8 days from her 1st mating and has been sick twice and is sleeping a hell of alot more???

sickness is normaly 3-5 weeks in ,she could be like this cus of infection ,you said shes on antibio this could be why shes vlike this x

Personally I've never had a bitch sleep more than normal in pregnancy.
