Boonville Animal Hospital has coke to our place for it twice. They were the kindest people you could have asked for. Sat with us and comforted us while we mourned. Not sure if you have to be a current client before hand, but if you don't I would highly recommend speaking to them.
Sorry to hear, it's never easy. Our vet comes to our house when it's time for them to cross the Rainbow Bridge. It's worth asking to see if yours might consider. Usually it will be towards the end of the day when they are done with their appointments etc. Sending good thoughts your way.
