Soooooo, now that pup is older, she plays longer and is out of her pen more. We play outdoors for any length of time 10-60 mins multiple times during the day, depending on the heat and if I need to sleep. The pen is indoors and 5x5 and located in the kitchen. She also has a kennel that's in my room but only uses it at night. I think she prefers the pen as it's near the other dogs for night sleeping and day naps. However, I want her in the kennel at night. I sleep off and on during the day when I have or had a night shift. I wake up to take Rogue outside and give her whatever she needs, water, potty break, play, sunshine. On my days off, she's outside more with me. Inside she gets supervised off leash and on leash time.
That's all just some background.
Heres my problem: recently she's been whining more and doing short barks while in her Ex-pen. All her needs have been met. I think she just wants to roam. I see it more early in the morning and late afternoon, but not sure if that has any significance. Usually it is also after she has just had play time.
We just started obedience class. I'm a public servant and my boss just granted me a set days off for 6 weeks so I could take Rogue to class. (We are not allowed to have specific days off every week.

)
What advice do you all have. Telling her "no" isn't working and I can't reinforce it with the collar as she is in her pen and I'm busy with household things or studying while she's doing it.
