I don't think having one heat would affect her personality to such an extent - at least this is my experience with full females. Their personalities as such might change a tad during heat, but my experience has been once heat is over personality returns to normal.


You are right to be concerned. This behaviour is not acceptable, especially to their owner. And she is not resource guarding YOU, well at least in the examples you stated, she has determined She is Over and Above you, and is protecting HER Turf and not you.


Your dog now must earn every single piece of food from you and your hand, and must earn the right to sleep in the bed with you. Thank means hand feeding their meals, and for each piece of kibble they need to do an obedience command or a trick - what-ever.


Look up the program nothing in life is free - NILF. There are lots of you tube videos on it.


I do understand your fear --- it is no fun being bit by a dog that is supposed to love you. The trick here is to be, feel, and act confident, as the pack leader that you are. Don't withdraw your love, but calmly, consistently and confidently you expect her to behave herself and to obey you .. ALWAYS.


Take her out for walks, reward and praise good behaviour. Play with her, love and pet her. But no trips up to the bed, until you can take her food away, walk by her food bowl etc. And for now, if you have her up on the couch and want to try that out, I would have her harness on her and a short lead. If she growls at you, she is immediately removed from the couch in no uncertain terms and very quickly. BAD GIRL. You don't have to shout it - just have disgust in your voice as you say it. She is removed and placed in her Xpen, playpen, or crate, and then you take over your seat again and ignore her for at least 10 minutes.
