If you download any Overwriting files - Make sure you back up your original files before placing these in your game folders!
Feel free to hex off of (and sell/trade/give away etc) any of the breeds on this page!

This file contains all the variations of the Basic file, as well as several other texture variations, plus brown and white dali spots. This file is a revamp and update of my previous "max" variations file.





Scottie Ears - Nutella / Tumble
Chi Ears - Willa / Basil / Frankie
Poodle Ears - Cookie / Corine

These are mixed breed pet files, bred from Sheepdogs with naturally occuring ear varieties. They were bred with the Basic Variations OW in and in order to produce your own Muttlie pups, you must have one of the Muttlie OW files in your game, otherwise they will come out as giant Muttlies (see stamp at the top of the page haha).




If you're interested in breeding your Muttlies from normal Sheepdog mixies you already have (either just for more variation or for different ears etc), you can't just put a Muttlie OW in, you will get giant muttlies! So, there is one important step you must do first - genex your sheepies!

1. Create a copy of the sheepdog pet files you want to breed (keep your originals somewhere safe!!)

2. With a Hex Editor, you have to Genex the scales on both gene sets to 75 (in hexadecimal that would be 4B).
(Check out the guide on Yabiko for more info on gene editing!)


(Screenshot only shows one gene set, you have to scroll down and edit the second set too)

3. Balance the Checksum (manually or using Petz Byte, downloadable on Yabiko)

4. Make sure you have a Muttlie OW breed file in your game (back up your original Sheepdog.dog!)

5. Breed to your hearts content! Your Sheepdogs will now produce perfectly and genetically correctly sized Muttlies! (baring any other non-sheepdog parts of course, being mixies, your muttlies may get some other non-"sheepdog/muttlie" body parts)
