Are danes difficult to train

Question
I have a 1.5 month puppy blue dane is that true that danes are hard to train if so when am mi supposed to start the trainning for my pup.
Can danes be trainned as a gaurd dog as they are good watch dog.

Whether is is advisable to make a great dane a gaurd dog?

Answer
Danes are no more difficult to train than any other dog.  They require firm and patient handling and training should start as early as possible.  However i suggest you take the puppy back for the time being as 6 weeks old is FAR too young to be separated from its mother.  Dogs, especially large dogs should not be weaned until they are two months old AT LEAST.  Preferably 10 weeks old for giant breeds such as danes.
