Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you today. I do apologize that your question was not answered before. Different experts come online at various times; I just came online, read about your wee one’s situation, and wanted to help.
How long has he had these signs?
What was hanging out? A piece of gut, something non-edible?
Can you take a photo of this to let me see what you are seeing? To post a photo, you can use the paper clip button on the tool bar above the text box. Or if you cannot see that on your phone/computer, then you can post them on any site (ie Flickr, Photobucket, Imgr etc) and paste the web link here for me to have a peek.
Any gagging, retching, lip licking, drooling or vomiting?
Can he keep water down?
Are his gums pink or pale/white? Moist or sticky?
If you press on his belly, any discomfort, tenderness, or tensing?
