Congratulations and good luck! One thing, though, change his name! Goblin has such awful connotations...

Don't worry about renaming a dog, he was probably given the name by the shelter and hasn't had the chance to really learn it anyway. Even if he hasn't, a smart dog will usually learn a new name in less than two weeks and a not so bright dog will usually learn a new name in less than a month. Names ending in "a" "o" or "y" are the easiest for a dog to learn.

Even if you don't change his name, please, please take him to obedience training. If you get a good instructor, you will learn wonderful things about your dog and this will help you and your dog to understand each other. The best relationship you can have with your dog is one where your dog understands his place in your home. He will be happier and you will have a loving, well behaved, and loyal new member of your family.

Good Luck!!!!
