Although they are predominantly carnivores, wolves and the likes of foxes will eat berries, roots and, frankly anything that'll get them by in times of want. As for my dogs over the years, mostly Labradors, like humans, they can have some likes and dislikes. One loves to munch into an apple or pear or similar fruits. Another wouldn't eat any crisps whatsoever, but liked prawn crackers.
A Dalmatian that lived in a neighbours house used to be destructive if left on it's own in the house. It was a little crazy (aren't they all). Probably separation anxiety I guess. So they would put it in the garage when they went out. Come Christmas time, however, they'd put the frozen turkey on a worktop in the garage. When they went out for a spot of Christmas retail therapy, the dog scoffed the whole, still frozen turkey. It died, of course. Anyway, a bit off topic..
