No Pets

A BepInEx 5 plugin for Hearthstone that hides opponent battlefield pets (and their corner platforms) during games.

Pets sit on the board next to the hero, animate, react, and occupy a corner platform. If you'd rather have a clean board, this mod keeps the opponent's pet from ever appearing — no pet model, no platform — in every game mode, Battlegrounds included. Your own pet stays visible by default; an optional toggle hides it too (pet XP still accrues normally — only the visual is skipped). Collection previews are never affected, so browsing and inspecting pets works normally.

Purely cosmetic and strictly local — only what your client renders changes. The opponent sees their pet as usual.

How it works

The game's pet board controller checks its own creation blocker (IsCreationBlocked) as the very first step of pet creation — it's the same mechanism Hearthstone itself uses to suppress pets in certain UI states. This plugin installs a Harmony prefix that answers "blocked" for the configured sides, making every creation attempt a clean no-op on a fully supported code path (the game's pet event handling explicitly treats "no pet object" as a first-class state). The corner platform is a separate corner-decoration system driven by per-side contexts; a second prefix zeroes the pet entry for hidden sides before it is applied. Both patches act only in actual gameplay.

Note for Battlegrounds duos: your teammate's pet counts as "not your own", so it is hidden under the default settings.

Installation

You need BepInEx 5 in your Hearthstone folder — via either route — then the mod DLL.

Option A — via Firestone (easiest if you already use it):

1. With Hearthstone closed, open Firestone → Settings → General → Mods and enable mods. This installs Firestone's integrated BepInEx into the game folder.
2. Launch Hearthstone once and quit, so <GameDir>\BepInEx\plugins\ gets created.

Option B — plain BepInEx:

1. Download BepInEx 5.4.x x64 and extract the zip directly into your Hearthstone folder (next to Hearthstone.exe), so you end up with <GameDir>\winhttp.dll and <GameDir>\BepInEx\.
2. Launch Hearthstone once and quit.

Then, for both routes:

1. Download HsNoPets.dll from Releases and drop it into <GameDir>\BepInEx\plugins\.
2. Launch Hearthstone. Verify by finding No Pets ... loaded. in <GameDir>\BepInEx\LogOutput.log, or by queueing into an opponent with a pet equipped.

Configuration (optional)

Edit <GameDir>\BepInEx\config\HsNoPets.cfg (created on first launch):

[Features]
## Master toggle for the plugin.
HidePets = true

## Hide the opponent pet and its corner platform during games.
HideOpponentPet = true

## Also hide your own pet and its corner platform during games.
HideOwnPet = false

Looking to skip the pet end-of-game sequence too? That's a separate companion mod: Skip-Pet-End-Screen. The two are independent — install either or both.

Building from source

Requirements: a .NET SDK (8/9/10), BepInEx 5 installed in the game folder (the project references its DLLs from there).

1. Clone the repo.
2. Edit <GameDir> in HsNoPets.csproj to your Hearthstone install path.
3. dotnet build -c Release — the post-build step copies the DLL into BepInEx\plugins automatically.

No game files are included in this repository; the project compiles against Assembly-CSharp.dll from your own installation.

Compatibility

• Built and verified against the July 2026 Hearthstone build.
• Hearthstone patches can rename or change the hooked methods (PetControllerBoard.IsCreationBlocked, CornerSpellReplacementManager.UpdateCornerSpellReplacements). If the mod stops working after a game update, check LogOutput.log for Harmony errors and watch this repo for an updated release.
• Coexists with other BepInEx/Firestone mods, including the author's other Hearthstone mods.

Uninstall

Delete HsNoPets.dll from BepInEx\plugins. To remove BepInEx entirely, delete winhttp.dll from the game folder.
