Sim Canine Federation (SCF)

Your first show dog. Your first champion. A kennel with a history of its own.

Sim Canine Federation adds a connected world of dog shows, pedigrees, breeding and kennel management to The Sims 4. Train your dogs, develop your Sim's handling skills and follow your kennel across generations—from a new litter to a place in the show ring.

November 12, 2026 — Opening-screen loading fix

The corrected Full Public Beta — 2026.11.12 Loading Fix (Packaging r2) has been submitted to CurseForge. If it is still awaiting moderation, please wait for that version to appear in Files; the older r3 file does not contain this fix.

I reproduced the startup hang and found an unintended T.O.O.L interface registration inside SCF's pedigree UI. The corrected core is independent of T.O.O.L. I'm sorry this prevented some players from loading the game, and thank you for reporting it. A startup hang may not create a Last Exception, so an LE is not required to report this issue.

What can you do with SCF?

• Enter dog shows. Take part in National and International competitions, choose a handler, enter your dogs and review placements and score breakdowns.
• Build a champion. Develop Show Handling and prepare your dogs through ring and stack practice. Follow rankings, results, titles and awards.
• Explore pedigrees and genetics. Browse dog profiles and family connections, and keep track of your breeding lines.
• Manage your kennel. Register a kennel, maintain dog records and follow litters across generations.
• Arrange breeding. Make stud requests and review breeding records and litter registrations.
• Use the dog market. Browse dogs by breed, inspect profiles and pedigrees, and manage advertisements and reservations.
• Follow a living canine community. NPC households participate in training, shows, breeding and the market.
• Train with equipment. Includes treadmills for large and small dogs, the show ring and the small-dog show table.
• Build your kennel. Includes short and tall fences, doors, dog hatches, windows, roofs, lights, wood-and-black finishes and plastic doghouses.
• Work toward the SCF Champion Handler aspiration. Improve your Sim's Show Handling skill as your kennel grows.

About this download

The November 12 full bundle contains 36 core files, an English README.txt explaining every file, and an Optional folder containing the separate T.O.O.L compatibility patch. Treadmills and the kennel/build set are included in this full bundle; they were not included in the older r3 download.

Keep all 36 core files together. Only the T.O.O.L compatibility patch is optional in this bundle. The patch is supplied as a normal .package inside Optional. Extract the archive outside Mods and copy only the core files unless you also need T.O.O.L compatibility.

Requirements

• The Sims 4 Base Game + Cats & Dogs (EP04).
• Custom Content and Mods and Script Mods Allowed enabled.
• No other expansion or third-party mod is required for standalone SCF. T.O.O.L, Better BuildBuy, MCCC and Live in Business are not requirements.

Manual installation or update

1. Save and fully close the game. Back up your saves and previous SCF files outside Mods.
2. Preserve SCF_Archives, which contains your own SCF history.
3. Remove older SCF package/script files and duplicates, including older standalone SCF doghouses. Do not combine this with r3 or the October 25 bundle. Leave unrelated mods alone.
4. Extract the ZIP outside Mods. Create Hikavelle - Sim Canine Federation directly inside your The Sims 4 Mods folder and copy the 36 top-level core files into it. Keep script files only one folder deep; do not unpack individual .ts4script files.
5. Keep or restore SCF_Archives. Leave Optional outside Mods unless you need the patch described below.
6. With the game closed, delete localthumbcache.package if present. Enable Custom Content and Mods and Script Mods Allowed, then restart if you changed those settings.

Read the included README for the complete file guide and installation details.

If you also use T.O.O.L

The optional compatibility patch is for players who have both SCF and the matching T.O.O.L version. Only if you use both mods, copy the SCF-Optional-TOOL-Compatibility folder from Optional directly into Mods and add the README Resource.cfg priority rules. No renaming is needed. Otherwise leave Optional outside Mods. Do not activate it without both mods. Remove the patch and its rules if either mod is removed. T.O.O.L itself is not included, and compatibility must be checked again after updates.

Testing and feedback

Tested on Windows game version 1.129.39.1030 using only Base Game + Cats & Dogs and the complete 36-file SCF set: the main menu loaded, live mode opened, the pedigree certificate opened, and four show participants departed and returned with results. A separate test with T.O.O.L and the optional patch successfully opened both interfaces.

SCF remains a public beta. These checks do not cover every object, interaction, operating system or combination of other mods. Some legacy TEST, Prototype and v07 filenames remain from the installed build.

Please try the corrected November 12 version and comment with your game version and whether loading, certificates and shows work. If something remains wrong, describe when it happens and include any available error details with personal information removed. A missing LE does not prevent you from reporting a startup hang.
