Tastes like chicken... and sock lint

And now, because I know you're dying to hear about it, more news about my dogs' digestive issues...
I went out in the backyard to throw some ball and change out the water dish this morning. As anyone with dogs knows, rule number one in the backyard is... (everyone all together now...)
"WATCH WHERE YOU STEP!"
So I did. But in the process of doing so, I noticed something odd.
Fuzz.
Yes, fuzz.
Another basic premise of dog ownership: if you are concerned about something that seems to be coming OUT of your dogs, it is far more pleasant to first search for remnants of whatever they were eating than to examine the results of the digestive process. So I went on a little hunt around the backyard and found several tattered pieces of fabric softener dryer sheets.
Right.
One mystery solved (the fuzzy poo caper) and several more pertinent questions raised:
1. How did the aforementioned dryer sheets get into the backyard? We don't have an Old Man Dithers on the block, but I do suspect some meddling kids were involved. (And they got away with it too, dammit!)
2. What made them seem like tasty snacks to the puppies? Last I checked, Downy had not entered into any joint ventures with Beggin' Strips.
3. Will this make them sick? And if it does, can they wait to see a doctor until their vet visit on Friday?

Questions 1 and 2 will probably remain great mysteries of the universe. You know, like the pyramids and the popularity of The Simple Life. But everyone seems to be feeling just fine, so at least we can put number 3 to rest.

Next time, we're getting a pet rock.
