I have a conundrum of two parts, scientific and spiritual.
First the details.
My female dog is 12 years old. She developed a mammary tumor about 2-3 years ago which was not treated because it had metastasized and doctors didn't think she would survive the surgery. She was hale and hearty until 2 weeks ago when that tumor on her nipple developed puss.
Parallelly she developed uterus infection also. Doctors did surgery to remove her uterus, and even though her survival possibility was low she survived.
But the prognosis is not good.
Her creatinine (which should be less than 1.6, went from 2 to 9 in just one week, which is killing her now. With no amount of therapy do doctors expect to get it down to under 1.6.
She is eating nothing. She drinks only water and in 5 minutes vomits it all with blood in it.
She is on drip and about 4 injections daily (This is since past 2 days. Surgery was done about a weak ago).
She is very weak and losing weight fast.
Any vet I spoke to predicts a life between few days and a month for her.
Now here's my problem:
Scientific conundrum: Euthanasia for her is being talked about in the family. Although it pains me to see her suffering, I don't want to euthanise her if there is a possibility of her getting better. But whether that possibility exists or not will only be known after her death. The larger medical consensus is that she would die, but basically doctors cannot be sure 100%. Maybe 99.9%, but not 100%. When cancer was detected in her 2 years ago her life was predicted 6 months but she is still there.
But if her death is a forgone conclusion, I don't want her to suffer even.
Spiritual Conundrum: In my country we don't like the idea of killing even animals. In the US they just shoot farm animals who are unhealthy, but here we believe in right to life, and that only god should make the decision of life and death. But I don't want that because of my cultural leanings my dog should suffer if there is a possibility that she does not have to suffer via euthanasia. But then there is that faint hope that until there is life there is the possibility of miracles, once death happens it is permanent.
I am very confused and conflicted. I try to think what would my dog expect from me, but am not sure of even that. I don't think dogs are capable of holding expectations, but again, I am very confused.
UPDATE :
We put her to sleep with Euthanasia. Thank you Keshlam and Elmy for helping me reach some clarity. Last night she was in pain and cried a lot. We couldn't take it and today took her to the hospital with Euthanasia in mind. Her condition deteriorated very fast. By the time it came to injecting her with the drug, she was nearly gone, but I wouldn't have her suffer for even a second which was not necessary, so went ahead with the process. She was gone the moment the drug was injected in her. I am at peace with what has been done. At least I now know for sure there was no possibility of her getting better.
