First of all, I am so very sorry to hear that you have lost your husband
I have been married for 25 years, and I just don't know what life would be like without Ron around
Your little Dudley sounds like a very opinionated little boy. And it also sounds like the couple who kept Dudley for you must have taken excellent care of him. Yorkies are very adaptable and in no time at all he will be back to his normal "love mommy the best" self.
