I have a 4.5 yr old Lab -- last nite he ate an yarn ball about the size of a lemon. We took him to the all-night clinic and they induced vomiting. None of the wool came up. He has been lethargic most of the day but no wool in his poop. I spent the day trying to get him to have a "movement." So far, no results. I hope that the ball stays intac. Our regular vet says we should not worry unless he becomes he starts having diarrhea or starts acting funny. He is really clam which is unusual for him. He is about 4.5 yrs and has eaten several of my hair holders and they show up about 2-3 days. I have been trying to take him out every hour for about 30 min hoping that the this will help him get out of distress mode. Any ideas on how to make him poop w/o a scene? TY, eliza
