She tried to snatch the food out of Marks hand. It wasn’t for her and that’s definitely not okay. You might be happy to have a badly trained dog but nobody else should have to put up with it.

She's probably getting next to no attention from Zoe and Alfie, probably getting hardly any walks, so giving her a stern telling off will make everything worse.
