Hmmmmm, mystery barf

Just another day in the life of a multiple dogs owner! It started out fine, a Sunday with no big requirements out side of meeting all the doggie needs,ie: walk them , feed them , take Ole to the local park for a solid 30 minute game of fetch with his favorite orange and blue ball toys. Abner with Elmo and Shelly showed up after about 20 minutes and all 3 dogs competed over who would get the ball first and bring it back to me. I have to get a head start with Ole on the fetch game because once little Elmo shows up Ole won't compete with him over the ball. Now, Elmo is very fast but I've noticed that Ole hangs back and lets Elmo get every one. Then it was home again for actual breakfast. They enjoy everything, especially seeing their arch enemy stroll by our house. The enemy is a small black and white probably border collie mix of some sort. We've never learned her name as usually her owner is too busy yelling at her to cease and desist as she snarls menacingly at my pack of 3 goof balls. Shelly views her with great distain and Elmo and Ole think it is all great fun. Everyone ate their breakfasts like it was the only food they'd seen in a month except for Shelly , who started off doing real well but after she had eaten 2/3rds lost interest and wandered away from her bowl. The land sharks were circling (Elmo and Ole), and as I did not want Elmo to eat any more (he's gained 2 lbs since Ole got here!) I put the bowl up on the kitchen counter and went about my other morning chores. Abner always worries that Shelly will starve to death if she doesn't eat every morsel in her bowl, so he apparently put the bowl back down and SOMEONE ate it all! I don't think it was Shelly. I was upstairs working when Abner told me he had to go run and errand on his bike. I came down after he left and , There it was...a large pile of dog barf in the middle of my beautiful wool carpet. Yes, I'm glad it wasn't poo but...no one stepped forward to confess the sin saturating my area rug...Expensive area rug I might add with partially digested barf. I have strong suspicions as to who the culprit is but I guess it doesn't matter. All 3 engulfed their dinners tonight so whoever had the upset tummy quickly recovered. While Elmo and Ole are downstairs watching football with Abner ,Shelly and I are upstairs getting ready to do a little reading of one of the Steig Larsson mystery novels.
