okay i have a chi that is a male and is always in heat i also have another female dog that is 9 months and 5 days ago i notice she was bleeding and the surounding of the vigina was popping out, know first i don't think my chi could even reach her even if they both were in heat and i usually keep my chi inside the house and she stays out but lately she doesn't seem the same whenever she gets on the couch she doesn't jump any more she gets up very slowly and my chi is always trying to smell her but she usually sits down and doesn't let him could it be shes pregnant or she just feels weired becasue shes going trough that change another think my chi doesn't try hummping her anymore he's just always smelling her butt.
