I'm looking for a mod that will stop dogs from following their owner everywhere.

It's really bothersome when I make my sim do something and then the dog appears, following him everywhere and starts sniffing him, stopping his actions queue.

I even went as far as locking the doors to keep the dog outside :/

Try this and see if it works: http://www.simfileshare.net/download/811841/

Modifies the PetFollow_Sim and PetFollowSimAround_Sim ITUNs.

Thanks I will try it out! :D
