From the look in his sharp eyes, his grey-and-white coat colour and his low-hanging coat, Elvis definitely looks like that he has some Siberian Husky in his ancestry. His body shape and his Irish-marked coat pattern give slight evidence that he may be mixed with a Border Collie. His ears share a combination of genetics from both breeds - The Siberian has erect ears and the Border Collie usually has floppy ears. Lots of dogs that are Border Collie mixes have this sort of ears. The shape of his muzzle also resembled that of a Samoyed's in the first photo, yet it looks more like a Northern Inuit Dog's muzzle in the other photos.
No one can tell you the breed of your dog without seeing a picture. Even so, it is hard to tell when your dog is still a puppy. Wait until your Dog is fully grown then take a picture and ask around. (I could give you a good idea of what breed it is if I could see a picture).
