Patient history: An unspayed female Corgi, who was seen "hanging out" with a male Bichon about 9 weeks ago.
I don't think you have to be a radiologist to make this diagnosis.
Look at that lovely jumble of heads, spines, and pelvises. (Pelves? Pelvi?)
Bonus points: How many puppies?
Hint: Count the skulls.
Congratulations! You win a brand new Corgichon, born this weekend!
