How to tackle possesivness

Skye is a lil madam again, tonight she snapped at vinnie because i accidentally dropped a piece of food i was chopping up on the floor .. i am going to start putting her in her crate while i prepare food now because food is the trigger to her snapping at him!.
She will snap at him if he gets too close to her treat, she will snap at him i he gets too close to her while she is eating her dinner in her crate, i have a feeling she had to literally fight her way to get food when she was a pup!! there was 6 of them all fed out ONE bowl :@
Anybody have any ideas how i can nip it in the bud, atm i feed her in her crate so nothing happens and treats if they are bones etc she has them in her crate too .. treats such as lil tiny things she dont get crated because her n vin will sit side by side and take one each and eat it and its gone so never a problem there .. she gets told NO!!! etc.
Has anybody had a food possessive dog too? she is only like it with vinnie, i can pick up her bowl and move it while she eats no problem.

Sorry no idea as you are already picking up her bowl and moving it.

I think you're doing all you can tbh. I agree that it could be because of how she was fed as a pup. A lot of breeders feed that way, it's easier than doing7 or 8 seperate bowls of food & making sure they don't steal off each other. I don't really like it, because a less forward pup could well be pushed out of the way & not get the right amount of food.

A food possessive dog is a pain in the backside & can be dangerous, but at least she's only like it with Vinnie (and probably other dogs).

I'd try feeding them one after the other & make whichever one isn't eating sit at the other side of the room (on a lead if necessary) while the other one eats. As it's Skye that's the possessive one, I'd feed Vinnie first so that she knows that even if he eats first, she still gets food afterwards.

It's a long shot, but it might help.

Thanks for the advice caryll .. i notice its more over scraps because obv she thinks its new i want it first!!! i never feed her scraps but if i drop something on accident thats when it happens n over bones etc.

I have fed her outside the crate for again since before xmas and she was fine, i would put vinnies food down first one side of the room then put skyes down the other side make her sit and give it her, id stand the in the middle of the room, they both finished the same time and all was fine.

Bones are often a bone of contention with dogs (sorry for the pun!).

It's often best to feed bones seperately - they're often a trigger for possessive aggression.

Yeaaa, deffo is in our househould lil madam lol
