hiya, someone else will be along shortly with more experience in labs, but from my experience as a dog owner, i have always known when my girls were in season, my rottie girl came into her first season at around 6 months and she was such a beginner there was blood everywhere on the floors! but i think maybe your girl may still be in season if you suspect it, thats the only explanation i can think of, but as i say someone with a bit more knowledge will be along soon hopefully, but i have never had a girl come back into season after a month, i hope someone can point you n the right direction.
