House training - Italian Greyhound

Question
Is it possible for an italian greyhound to ever be housetrained?  can we trust it alone for few hours at home?

Also, are there any other dog breeds with similar qualities that are easier to house train?

thanks

Answer
The best way with any breed is with a crate,and what you do is leave them in there except to take them outside,to feed them,to play with them ect and do that for about three weeks and slowly let them out more

Chihuahuas are simular to Italian Greyhounds as well,and are pretty easy to housetrain also Yorkshire terriers
