Food guarding: call her name and when she looks at you, give her something that she likes way better. Then walk away, no further rewards or praise so she learns it is part of life (again).
And never her board her with your BIL anymore.
But also, she may have hit the bratty stage in the meantime and good luck with that; I am in the middle of all that stuff.
I think im ok with the food guarding atm. Just took a couple days to kick in. But still cant feed her raw bones. She turns into a devil with raw stuff. But I just eliminated the problem. NO RAW
