I had my pup for three weeks now, she will be nine weeks monday. I had never had a problem with food aggression but today I got her a elevated feeder and she was eating and i went to adjust the feeder(move it back a little) and she growled and turned her head towards my hand. She has never done this before and I have taken food away from her before(moving the bowl to clean). Why is she doing this now, she just started this today. Please help because I dont want her growing up with this
