I know it has been months since we've contacted but everything is going great!  Odin (from Suma and Cookie) is now 7 months and was neutered on Tuesday.  They said he was such a good boy.  He trotted right out of the back room happy as he could be when we went to pick him up. :-)  Now that it is getting nice we take him with us almost everywhere--he gets a BIG kick out of that.  If he sees that leash he is out the door and climbing into the car no problems.  He graduated from puppy school by the time he was 4 months and is doing well.  He weighed in at 88 pounds on Tuesday, he's getting so big!  He's a very good boy and we are thrilled to have him with us.  Enclosed are some pics.

ps- I will send you a copy of his proof of neuter certificate sometime within the next few days.
