I can not find any wolves in my world and when i get a spawn egg it still does not work im currently using mod version 1.0.4 with forge version 1.7.10

Make sure your game is not on peaceful, they don't spawn in peaceful

Yes thank you im so stupid :') It was on peaceful but i turned it to normal now it works perfectly, thank you again!

That must make me stupid too then :P I've done that at least 5 times testing the mod because I turn it on and off peaceful to clear the wolves haha. Have fun with the mod!

@crickymc1 did you get this sorted out? Hopefully it was just a matter of being in peaceful mode. Otherwise, try version 1.0.5 . It's the first version that I'd confidently say has good spawn mechanics in place.
