Old dog leaving calling cards

Pogo is a lovely girl. Having had old dogs in my life, I would bet she doesn't even know she's leaving those little marbles laying around or where theycame from. There is also the possibility that her lack of awareness is a side effect of her meds, Regardless, I'd handle it the same as the poster above, I would just dispose of them as calmly as if Pogo were your dear great-aunt. We all get old, "stuff" happens. Puddles around the house are much harder to deal with. We've been that route, too, because of heart meds the dog was taking. Just enjoy her until she is not having fun anymore. You'll know when that happens and can deal with it then.
