We got our puppy at 7 1/2 weeks and she had never had an accident in her crate. She is now 9 1/2 weeks and for the past 4 nights she has started peeing in her crate. She has always cried when she has to go, but she had not been doing that anymore. I don't know what to do. Should I take the blanket out (maybe she will learn her lesson if she pees and actually sits in it) I can't figure out why she would be doing this all of a sudden.
