Answer:
The 10 largest breeds of dog are
1. English mastiff

I edited the above 3 because i know them for a fact, and I'm pretty sure #10 is wrong also.4. scottish deer hound
5. bermese mountain dog
6. greater Swiss mountain dog
7. greyhound
8. elk hound
9. malamute
10. Siberian husky not Alaskan husky, there is no such thing, it is SIBERIAN not ALASKAN.
