as a breeder at 7 month old she should be going for walks to get all that Terrier energy off her, also play sessions should be like 20 minutes, she is full of unused energy and you have to train her, also her pooping habits have a lot to do with feeding times, she should be eating at least twice a day NO free feeding, water should be available all day but pick it up about 8 pm and take her out, she SHOULD not be peeing in her crate, also put her crate in your bedroom, that way she will not feel alone, that is MISTAKE #1 with new puppy owners, they put the pen and the crate in the bathroom or kitchen, she still young and don't want to be alone.
HTH,
best of luck with your girl..
