Yorkie 118 please stick with it. Yes it is overwhelming, these little guys arn't like regular dogs they really need a lot of attention.Your lucky , like you said you have the time at home to succeed.I crate trained Tia and found after 3 mths she didn't require the crate anymore as she would stay in her little bed when told.
Like the others have said, it will be so worth it and a friend for life. Chin up honey, sending hugs.
