> So what do you think i should do? Stop the children going near him when he has something like this?
My children are told to
never go near the dog when he is eating, even though he has never shown any signs of food guarding and actually prefers somebody to hold a chew for him to chew on.
Kids can't help but pat a dog when they walk past, they often aren't even aware of doing it! so one can never assume a child will leave the dog alone
(this from sombody whos toddler was snapped at, years ago, by my own dog when he was eating -
). Vigilance is the key.
If you want to give your dog treats, make sure he has somewhere he can go to where he will not be disturbed by the kids.
>I was actually a bit nervous of taking it off him, but offered him a bit of cake and he swapped quite happily
Swapping is PERFECT

>I didn't tell him off as was slow to react to it all and felt he wouldn't know why i was telling him off as was too late.
You're right, he wouldn't know why he was being told off and it would probably make him worse with guarding food, well done for not telling him off
