Our terrier chewed a sock at 10 months old, it ended up wrapped around her intestines. When the vet removed it one of the cuts to her intestines didn't heal and started to leak. This went on for two weeks, and she ended up having to be p.t.s cos she had peritonitis.
So after about 5 operations, all of which failed, a bill of £4500, and no dog, we are still pretty f**ked off with the whole thing!!!
