Dead dog....what to do?

I am so sorry for the loss of your beloved dog. Its going to be a very hard thing to do with emotionally thats for sure. If he was gone 6 months, he may be only bones depending on the climate and weaqther conditions. I would bring a bag just in case he is still in tact and starting to decay some because as you said you do not know how long he has been there dead. Also bring a box to place the bag inside of until he gets cremated. I hope you all do well emotionally.
