Thread: Advice wanted on our 9 month old pup please

A dog will show food aggression to a subordinate, so in simple terms the dog does not see you as above her in the "pack".
You will need to teach her that you are the all powerful giver and taker away of food and what you say and do matters to her.
It's also handy for when the dog comes across something you don't want them to eat ( dead rat etc..) so no matter how much they want to eat something, if you say NO then it doesn't get eaten.

Good luck. Try working on obedience until she gets the idea what you say needs to be listened to.
Hard work trying to break a habit Vs stopping it as it develops.

PM me if you would like to chat about moving you up the food chain
btw patting and praising for 30mins after she has growled at you is not really going to work since she made the threat and you relented by providing her with confirmation she is in charge.
I've been through the same thing with a 65kg Rottie bitch who was dumped on me by her owner. Lucky it turned out the hippo just needed some boundaries set and came right before anyone got the chomp/
