Oh Dixie, what a heartbreaking decision to be made. I know how much you love Dixie and Dusty. I'm trying to find the words that I want to say and it's very hard to do. I feel that you have gone through motherhood with Dixie, she did well, she had wonderful pups and you got to have all that puppy breath during that time.
Dixie did her job wonderfully, but it did take a lot out of her. I want to say yes, yes have more pups, wouldn't that be great, but I can't. Dixie is your love, your dog of all time. Our time with our pups is so short, why not enjoy her, have fun with her and just tell her how much you love her, and don't forget she gave you Dusty. I have to agree with the others that it is her time to be spayed and be left to enjoy her life. I wish there were more people out there like you who put their pup before their own wishes.
Jackie
