Our pups change alot the first year, why it's good to start classes and continue.
Sounds like she may be mixing up play when you want to instead have a mission (like leash up to go outside). And she'd rather do her game (run around the house and not get the leash on).
Do you clicker train? Be able to work thru alot of the issues, specially to have her like the leash.
You are right to NOT take her to the dog park until you have a reliable 'come'.
How is her 'engagement' work going? How much FUN is training with you?
