If you've already made the linguistic leap of referring to your dog or cat not as a pet but as an "animal companion," you may be on your way to exploring emerging euthanasia services that claim to be more humane — or, at least, less traumatic for the humans paying for it — than the traditional unpleasant final trip to the vet. A Peaceful Passage offers at-home hospice care, at-home euthanasia and assistance with burial or cremation arrangements, as well as an experienced veterinarian, Dr. Christine Daigler, who responds to middle-of-the-night house calls and has an impressive bedside manner with ailing four-legged friends.
