she is still eating perfectly normal, consitpation was my first thought as well, but not they normally TRY to poop when they are constipated? Misty wont even try, she walks outside she pee's and walks back in even after eating, all the other dogs poop right after eating and she walks out pee's and comes back in. she is not behaving as if she is in pain or ill her tail is the only clue, and unlike Happy Misty does not hide it when she is hurt or sick, sh exaduerates it lol
