help!! my pit went into heat in May, right on time. we kept the dogs apart the whole cycle. then in june my female started swelling and bleeding again. she didn't show any signs of going thur heat again and my male wasn't to interested in her , then I woke up and they were stuck. she has gone into heat 3 times and has had 2 litters. can anyone tell me what may have happened? can she get pregnant since she had her heat in may?? is there a such thing as false heat? im really confused especially after reading all on this..i cant find an answere!
