A hot dog baked in a bread pastry.

Answer 2

Here's what I found on it...

The allusion is to one of Aesop’s fables, written about 600BC, in which a dog was taking a nap in a manger. When an ox came and tried to eat the hay in the manger, the dog barked furiously, snapped at him and wouldn’t let him get at his food, food that, of course, was useless to the dog. At last the ox gave up and went away muttering, “Ah, people often grudge others what they cannot enjoy themselves”.

Kinda like an ex-husband lol.  He doesn't want his ex-wife but doesn't want anyone else to have her either.

LOL  Hope this puts it into perspective for you.
