Dixie, good for you, just stick to your plans, since you will be working while you are taking these classes he will mellow out.
Let him see that you can be a success at it and I think he will change his mind. You only have one life, live it to the fullest. Years from now you would be saying I wish I had done that, but it's too late now. Your a natural with dogs and I know you will be successful. Good Luck.
Jackie, Miss Daisy and Perry
