Thank you for your response. I was alittle worried about it, wondering if she would wake up from the anesthetic. Is that your reasoning on why not to have her get surgery? I will not get her fixed until her heartworm treatment is completed thanks to your reply. I would have asked the vet anyways, but they are so judgemental concerning alternative heartworm treatment, that I really didn't want to hear about how "It's not fair to her." Blah, Blah, Blah. Thanks again!!
