A Complete Dog-alogue: Taming a wolf gets you the A Complete Catalogue Advancement

I built this really cool city by the water. It (at the time of writing) has 3 buildings, one of which with no door (I feel this is important because technically the doors make it count as a Village). There was a wolf that followed me around throughout the building process. I eventually decided to tame that wolf, and I got 2 advancements: A Complete Catalogue and Best Friends Forever. I thought of a pun for the title and immediately reported the issue.
