Hello My baby boy has had his first erection tonight and I'm not talking about a little bit of lipstick I am talking about the full works! I have never owned a male dog before and I was hoping someone could tell me what this now means? I am looking after a friends dog next week and she has not been done. Does this now mean that he could get her pregnant? He is only 4 months old and I think it is all happening very early, is this normal? Help would be much appreciated on this sensitive issue!
