she is just having her first season is it normal for her to bark at everything and anything also when i took her a walk (this was before i noticed she was in season) she ran away but did come back she normally walks by side all the time thanks for you response

Personality changes are quite usual when bitches are in season. Some of them turn into Houdinis too, so keep a close eye on her - the running away could have been a practise run ( I have one who would never go anywhere until she's in season when, given a quarter of chance, she's off scouting the countryside for likely mates). Hopefully, she'll return to being the "normal" dog you know once her season is over.
