Hi guys, would really appreciate your input.
At the beginning of January I had a giant breed bitch come to my boy, sadly she missed. The puppies would have been a month old now. She normally has 2 seasons a year, 6 monthly. Today she has been round for a play date with my boys today and both my boys have been incredibly interested... one is very experienced, the other has been used once before. They aren't humpy dogs as a rule, but both were latched on as though she was at her peak, both pinking. So we thought it was best to shut them inside out the way to calm down. We inspected her and no swelling, no bleeding etc, infact no signs whatsoever. She has been scent marking everywhere here, which she doesn't normally do. She's been well in herself. My boys are pretty good at spotting the right day and generally aren't interested if they aren't.
She hasn't been around any other bitches and has had a thorough bath at the beauty parlour since finishing her season too. She hasn't flagged at all, but she didn't at all during her season anyway.
So, what do you think it is? At first I was thinking silent season... but no swelling, then was thinking infection, but she just seems so well in herself and nothing out of character, then was thinking maybe she is due in season soon, but then why were my boys trying their luck now when they normally show no interest?
My boys were very very interested, like she was at her peak?

Any advice or input gratefully received.
