Maybe I'm just too suspicious.
Has it ever occurred to you that your human might deliberately purchase snacks containing chocolate, or other dog-unfriendly ingredients, just to avoid sharing?
This thought crossed my mind when out for a walk with Gail on Sunday morning.
We were happily strolling through the woods at Cambus o' May when Gail decided to stop for an 'elevenses' break, and took a flask of coffee and a bar of flapjack from her bag.
I put on my best starving dog look, but Gail pointed out that the snack was labelled 'chocolate-flavoured' and said firmly: "Not for you Bertie".
I'm pleased to report that, following my prompt, Gail did finally release a few crumbs for me to hoover up before we set off again through the forest...
