I'm laughing my butt off at your dog Lou,
my dog is not nearly as entertaining (though a lot less trouble I suppose).
He is a tissue-thief though and will shred any napkins or tissues you leave around....
he's gotten quite a few 'treats' off my MIL who just doesn't remember to keep food out of range... got a whole egg mcmuffin one day
He is such a freakin picky eater though... loves all people food... except bananas apparently, lol... starve himself for days when he's being picky about his own food (and we currently give him wet food over dry kibble and even warm it a touch in the microwave for him....)
I wonder if it would be healthy to let him live on cheerios?
(for the record we only recently let him eat some people food and thats cleaning up after Daniel and is usually stuff like steamed veggies, avocado etc...)
Lou - I did read one woman's post on the facebook page for breastfeeding that mentioned mucus in her kid's poop and she said it was yeast-related. Just thought I'd pass that tidbit along in case it fits your situation.
