I'm so glad its all ok, i have only just caught up on this thread, i had my boy done just over 2 years ago, it all went well, about a week after we saw a red tube sticking out from the wound so took him to the vets and they just cut it off, i think it was once of the stitches or something.
However the day i dropped him off i cried and cried, (i had taken the day off work,) we dropped him off at about 8.30am and they said they would call between 2 and half past that afternoon with an update, 4 o'clock came round and no call.......we assumed the worst, so i cried some more, called them and struggled to get my words out and tell them who i was, they said he was doing well and we could pick him up in an hour and then i cried even more but these were happy tears and said thank you, they must have thought i was a right nut.
