The only time my mom has a problem with a dog burrowing in the clean laundry is when she puts it in "Mia's" rocking chair. There's a rocking chair near the Christmas tree that Mia sits in a lot. If the clean laundry gets put in it (just long enough for mom to start another load) then Mia is in it.
Other than that she doesn't bother it. Mia is the only one that gets on the furniture, the other two would rather be on the floor. lol
I've got a bad habit that when I go out to the store, I always bring something back for Mia. Mia has started to expect it too. It's always either a new toy, a rawhide of some sort, treats, or something. I can't help it. lol
I thought about getting her a new pet bed, but she's got a habit of tearing them up lol. Right now, in their 'room' they've got a cage without a door as a bed with a sheet in it laying on top of to furrying dog things my mom bought when we got our first chihuahua. Well, Mia drags the sheet out of the cage and through the house.
The last time mom washed their bedding, Mia was trying to drag the hamper of clean bedding. (it was a small hamper) It was adorable.
We've had 6 chihuahua since I was a baby. They have all been so laid back and quiet, except Mia. She's hardly ever quiet and when she is, she's either into something or sleeping. There's never a dull moment with her.
