I would probably go with something else before formal euthanasia again. I took Cher in to be put down by a vet when she was beyond hope. It took four shots and almost three hours for her to pass. Meanwhile she had bouts of confusion and was stressing as much as the drugs would allow her too. It had been similar with Shania but that time I just blamed it on all the tumors blocking the drug from getting to her heart effectively.Boulder Humane Society euthinaisis birds for $30. Maybe your humane society would do that too?
