We are getting a new Vizsla, Sophie, in 2 1/2 weeks and she will be 9 weeks old when we get her. Either my husband or I will be with her throughout the day and plan to play and exercise her throughout the day but I am worried about what to do at night and it looks like we should crate train her. What is crate training and how do I learn what to do??? ??? We have not had dogs since we were kids and have never trained a puppy. Is there a book to read or can someone tell me what to get and then what to do? What do we put in it? How do we use it for night and potty training?? Thanks so much!!
