My bitch isn't due in season until feb ish she is 16 mths old and entered for LKA on friday, question is i walked her on the weekend with a friends male who is approx 6/7 mths and he seemed really interested in her backend,  and also she has been doing a lot of cleaning down there, so two question could she come into season now if she only had one 4 mths ago, and the second question do i still take her to the show even though there aren't any physical signs i.e. bleeding at the moment?  would hate to upset anyone there, but would also hate to miss it for no reason.

I don't know about the showing part but my bitch comes into season every four and half months

Some dogs will react to a bitch weeks before she actually starts her season.
