If she tries to bite, even playfully whack her on the nose. From her viewpoint you are just another dog pack member. If you allow her to bite without any correction she will take more liberties in " correcting you" for intruding upon her personal territory, and/or use it to seek dominance over you as the alpha member of the pack.

Of my 3 dogs 2 of them went through a nippy stage. The latest has graduated from a nipper (with correction) to a licker. He's quite good at sneaking up on me to land a well placed smack on the lips. Yuk.


Obviously they will act more agressively towards strangers which is not a good situation.

Per the flowers you might try boundry training on a leash. Place rocks or some border if one is not present. Then walk her by the boundry. If she crosses pull on the leash with a NO. My previous dog of 11 years would not go within anything that had a circle of rocks around it or the "magic circle".
