After getting a job as a model for a diaper ad, Soma finds himself stuck with the contract.
Unbeknownst to him, Firebreath got an even rawer deal; the fact that he never really grew the while belly fur common to Golden Retrievers still gives him that puppy-ish look, which the ads' directors thought was much more fitting for the girl advert instead.

Note: I'm not really into the sissy stuff, but it can be fun every now and then. ;P
