Animal Hospital (Anomaly): Harlow’s Favorite Update — What It Included
Harlow’s Favorite Update has wrapped. The patch ran in Animal Hospital (Anomaly) from July 10, 2026 to July 12, 2026 — a compressed 48-hour window rather than a lingering season. Named for the game’s Dr. Harlow character, it was a visuals-and-characters pass: new class looks, reworked skins, a fresh batch of items, a rebuilt Dr. Harlow model, and, per the developer’s listing, a couple of deliberately hidden additions that only surfaced once the update went live.
With Harlow’s Favorite Update closed, the next scheduled update is The Hazmat Arrive, running July 24 to July 27, 2026.
The drop landed while the game was operating at real scale. Animal Hospital (Anomaly) has pulled in more than 780 million visits and sits above 1.2 million favorites, with a live population in the hundreds of thousands through the update window. Interest in the patch itself was heavy too, with the going count climbing into the millions on the event listing.

What it included
The developer framed this as a visuals-and-characters overhaul rather than a new mode or map. The changes covered:
- New class visuals, with several existing skins reworked
- A batch of new items
- Overhauled security and secret agent classes
- Redrawn in-game 2D icons
- A reduced-flashing-lights mode for players who needed it
- A new Dr. Harlow model and a set of new Dr. Harlow interactions
- A redacted interaction and a new lore character the developer kept under wraps until launch
The teased interaction and the unnamed lore character were the wildcards. Both were marked hidden on the listing ahead of the patch, so what they added only became clear once the update was live.
When it ran
The window was short. Harlow’s Favorite Update opened July 10 at 12:00 PM ET and closed July 12 at 12:00 PM ET — a straight 48 hours.
At two days, this was a content patch built to be caught while it was up, not an event to circle back to. The opening hours were the busiest, and anything tied to the update had to be done inside the window — there was no extended tail once it ended.
How it fit the game’s rhythm
Animal Hospital (Anomaly) leans on short, punchy drops rather than long seasons, and Harlow’s Favorite Update fit that pattern. The Hazmat Arrive follows about two weeks later and runs a day longer — a similar quick-hit style, though it’s too early to call it a fixed cadence off just these two updates. Worth checking back as it approaches.
