THANKS EVERYONE FOR YOUR INPUT!
The overwhelming majority of you vote to spay. I guess in my heart I had already made that choice too or I wouldn't of made the vet appointment. She is scheduled to go in on Feb 12th.
Some of you brought tears to my eyes with your thoughts. Especially Leslie when she said she would want one of Dixie's pups if I did have another litter. What a high compliment since I know how much Graham is loved. Leslie, when you do want another pup and if it's a Golden let me know because I know many people who breed reputably for the betterment of the breed.
Several of you said Dixie has done her part and you are all right! She has and I don't want to see her age faster than normal. Our time with our beloved pets is so short as it is. Thanks for all the input and making me feel more comfortable with the decision to have her spayed. You guys are great cyber friends and I cherish each of you and your ability to tell it like it should be! :D
