You haven't lost your mind, you just now found it! It won't be the last one you will own. Once you've been bitten by the pointer bug.....All joking aside, enjoy your pup and keep us posted on how the setter/springer combo works out. Have been thinking about that myself.
But I must confess, I have also been considering an English Setter to add to the pack. But not now, I have my second English Cocker Spaniel puppy to train. I don't ever want to be without a field bred Cocker/Springer either. Too many good dogs and not enough room for em all!
