Looking for a comic!

It's of Pomni and Jax, and it's a combined thought bubble of both of them. Jax is in a collar and leash, and Pomni is saying "Who's my good boy?" And Jax's response is "I am. I'm your good boy, Pom-Pom!"

I can't remember the original artist's name, but I could've sworn I had the comic saved. Any help would be great!
