My pooch decided a piece of thread looked tasty. Unfortunately, there was a sewing needle on it...oops!
Sounds like one of mine - he swallowed not just one, but TWO socks one time. Swallowing one is bad enough, but going back for seconds is just bizarre. After a day or two it was obvious something was wrong, wouldn't eat and couldn't get anything out (either end) and just didn't act right. The morning of his vet appointment, he left us a present in the laundry room - an enormous loaf of, something. Bagged it and brought it to the vet and found out it was a pair of socks.The last time he was in the ER was for eating some kind of yard decoration - a plastic chicken. lol Damn dog! It was the size of a small apple and they had to open him up to get it out.
