It's GREAT she's not using the pee pad in the crate. The entire point of crate training is they do NOT want to pee where they live!
If she's 5 months old, how many miles of exercise is she getting each week? Off leash is best.
Are you able to socialize by taking her on car rides for a few hours of visiting new people/places/things each week?
How are the puppy classes going? She do well in class?
You able to get a good start on ---> Top Training Expectations for Puppies
I know it helps me to review alot of training because I tend to rush and skip steps, causing a breakdown in the training. Have you gone thru this lately --> What is crate training (why put my puppy in a cage?)
