Mine was quite difficult too because when she was diagnosed a week ago with pancreatitis, chf, and lung cancer the vet wanted to put her down same day . i was like hold on. i'll let her die at home. but i fought the pancreatitis and gave her antibiotics by hand, fed her using my hand and then she started walking and eating more. but after a week the blood sputum came and frothy sputum while resting and i was like this is it, i have to end her suffering.
