What do I need to do to bring my dogs to Singapore?

We have 2 wonderful bull mastiffs and they are family, An opportunity may come up to transfer to Singapore and I would not leave our dogs behind. I read that a very few breeds are allowed in but have to be muzzled when in public. Our dogs are a part of our entire community and attend community events and sports events. The thought of transporting them and then going from 3 acres to small lots is one thing but this is something new entirely. I can not imagine having to muzzle them when going out. Can someone confirm this information? Thank you.
