Boredom Help

Hi Guys
Well last month we were starting to lose it as Dusty was messing almost every day while we were out. well with a lot of great advise from you all we have followed your tips and have had a month clean. Now we are looking for different help. what advise can you offer for when we leave her to stop her getting bored? We leave the radio on, she has a chew, some toys. What else can we do. Don't just want to leave loads of food because that would be wrong we just think she may like more stimulation. Have looked online but found nothing that we don't already use.
Thanks to you all in advance.

Is she getting bored?

don't think so but today shredded the letters. that can easily be resolved with a mail box but want to make sure she doesn't get bored.

I don't think you can do anymore, stuffed kong maybe?

Katy will shred letters if she can get to the letterbox before I do but that's cos she love Vince (our posty) but if left I give her a filled kong & leave radio on for company & hope I get in before posty arrives   

A stuffed kong is great for keeping them occupied   

We give Darcy a stuffed kong when we go out
