My dog was laying on a towel while his bed was being watch. I told myself to watch him closely so he doesn't chew it. I left the room for less then 1 minute and when I came back I had noticed the towel had a bald spot in an area with a thread sticking out. He might have chewed and swallowed some thread from the towel. Well he be okay? I called the vet but they haven't called back yet. The towel was not wet where the thread was missing which makes me wonder if it was already like that. Usually when a dog chews on something or bites something its wet. Not sure what to do. I fed him some wet food so if he ate thread it would pass with the food?
