Barley Boy is sick

Poor Barley, our energetic but adorable Labrador who is still a puppy at 9 months old is not well.  We took him to the vet this morning as he had been sick and not keeping anything down for the last 2 days.  It wasn't until last night that I discovered all of the buttons on my winter coat were missing and I found half of one in our lounge.   I can hazard a guess who had eaten them.................our errant puppy who ate a packet of strepsils when he was 6 months old but didn't seem to effect him (he just slept for the afternoon)!  We are waiting for the call now as the vet is filling him up with special liquid to find out where the blockage is - the X-ray showed nothing as the buttons are plastic and don't always come up on X-ray.  Fingers crossed he doesn't need an operation...............poor boy.
