k-9 castration

Question
My chiuhauha just got castrated two days ago and got suck with a female. will this affect either animal?

Answer
Hi Julie!  I apologize, as I am not quite sure I'm understanding your question.  Do you mean that your chihuahua has been in contact with a female chihuahua since his castration?  Once a male is castrated, there is absolutely no way they can inpregnate a female dog.  Does that help?   I'm sorry!  If I don't have this right, please write back and set me straight!  Thanks!
