I must share our success. My gsd has been showing signs of being possessive around his food in particular any recreational bones, also he is raw fed  I have been really worried as it has been getting to thepoint when I was worried about anyone inadvertantly walking passed him and whether if may push him to snap or worse. Something he never does normally .
Our solution ( after discussing with a couple of trusted friends one being his breeder- sign of a good breeder always there)  I started giving him  handfuls of food a piece of chicken here a bit of beef there when feeding him his main meal buy calling his name and showing him the prize I have got . We then advanced to hiding a few bits around the garden and some in my had as a game to finish his dinner. Today I gave him a beef rib (I had stopped all large bones as recreation until now) came back out with a bit of chicken called his name and he ran to me drop the rib took the chicken and was happy for me to hand him back his rib bone.
i am so proud of him. We will keep this up maybe not everytime but frequently and hopefully he will see me as the bringer of treats not the remover of prized possesions.
I intend to follow this on with members of the family so we are all seen as safe. All in all this has taken about 4 - 5weeks and its no use being squemish about handling raw meat lol
btw we dont have little ones and i would separate him to any visiting children if he was eating I am not taking chances even with this success.   

Well done :-D You should be equally as proud of yourself, as it takes comitment to achieve a change around like that :)

> its no use being squemish about handling raw meat lol

LOL it's especially gross with raw tripe

> btw we dont have little ones and i would separate him to any visiting children if he was eating I am not taking chances even with this success.

I think that's very wise :) Buser has never been guardy around food (started him off as a pup with the same method you've just used), but I always make sure the kids stay away from him when he's eating his grub, always better to be safe than sorry :)

Well done again, it's great to hear of success stories :)

Fab you must be really pleased. Another tip I was given years ago is only put a quarter of his dinner in the bowl and trickle the rest in a little at a time whilst speaking to him. Again he gets used to a hand that comes adds something rather than takes away.

Yep i think thats kind of what I was doing. but thats a good tip thank you  I agree I should have started off this wasy but unfortunately he showed some signs of this problem as ayoungster and I was given BAD advice ie keep removing him from his bowl move the bowl show whose boss and that was from an expereinced gsd handler/trainer.
Never having had this problem with my other dogs and didn't know any different and certainly have seen various tv trainers use this type of method. We kind of thought it was sorted but then things got bad recently. I had stupidly not spoken to his breeder think I was abit embarassed silly cos she is lovely and so helpful with her babies.
Next time I have a pup I will know better. Well you learn from your mistakes (sometimes lol) and will keep up with the games he loves to "find it"

Yes my GSDs used to love that too- It's also a great introduction to tracking which they love too.
