Hi, I don't have any experience with this exactly, but my Blossom will whine after being in the crate after she eats. She doesn't bark or throw up, but I usually place them in the crate for 10 to 15 minutes after they eat, just to let their tummies settle after eating, otherwise they play and rough house with each other and this can cause them to throw up right after eating. They usually have to go pee and poop 15 or 20 mins after they have eaten, so then I take them out, and then they are fine to play and run around. Maybe Ox is barking to let you know she needs to go potty after eating? Try taking her outside after her meal, and see if this helps.
