Keep dog stimulated while working?

Hi all,

We have a 9 month old English Cocker Spaniel. We had her from around 9-10 weeks and at the time of picking her up I had a super flexible work schedule which allowed me to basically work around her.

However I’ve recently taken a new role on which requires me to be in office 5 days a week.

While we’re working she stays at home, unfortunately some days up to 7 hours, in a fairly sizeable play pen as we can’t fully trust her to not demolish the entire house while we’re gone just yet.

While watching her on the camera she starts to get restless around 11-12 in the morning and completely disregards any toys and chews she has in her pen and chews (and eats) her bed and blankets, it’s gotten to the point where we can’t leave her with anything at all to sleep on because she’s thrown up bits of blanket a few times now and I’m worrying it won’t be long before it blocks her up. We’ve looked into a daycare type thing but we live in the middle of nowhere and the closest one to us is about 11 miles away which isn’t really viable on a work day.

What ideas can you suggest we do, things we can buy etc. to keep her entertained in the daytime. Snuffle mats are out of the equation as she will eat the whole thing.
