Oh, I am so sorry! My only experience is with lymphosarcoma. I did the whole chemo thing, but Nikki only made it to treatment 8 of 13 - she just couldn't tolerate the chemo. Of course, that was 3 years ago and I didn't know about GT and the wealth of experience others offer so willingly. We did consult with Dr. Couto who not only concurred with the chemo protocol but agreed when it was time to suspend chemo. This is very, very hard to say, but had I to do it all again, I would have just made her as comfortable for as long as possible and just spoiled her to pieces without chemo. She did end up with 3 good months after the chemo was stopped.
Only you can decide what's best for Abbey and you. DO NOT feel guilty. DO NOT condemn yourself as selfish. I beat myself up on both sides of that fence; I should never have done any chemo or I should have done more research on meds that would have made her more comfortable during chemo. I should have fed her MickeyD's. I should have taken her to an oncologist. And on and on and on. At the end of the day, I was dealt a hand and played it to the best of my ability. I will always love Nikki with all of my heart - she was my heart.
I hate this disease. I hate the fact that not a day goes by that another beautiful greyt dog is diagnosed or crosses the bridge. I pray that in my lifetime there will be a cure or at least more of a fighting chance. I pray that someday I will hear Dr. Couto say that the the 2 of 3 odds that racing greyhounds will get cancer that he told his audience at 2008 Sandy Paws are changing in the greyhound's favor. Most of all, I pray that you and Abbey and all of the greyt dogs with owners fighting for their lives will have many sunny, fun filled, love filled days together.
