Making The Decision to put down your beloved Pet. Perhaps the kindest thing you can do for a pet that is so sick or so severely injured that he or she will never recover normal health is to have your veterinarian induce its death quietly and humanely through euthanasia.Your decision to have your pet euthanatized is a serious one and seldom easy to make.erhaps the kindest thing you can do for a pet that is so sick or so severely injured that he or she will never recover normal health is to have your veterinarian induce its death quietly and humanely through euthanasia. Your decision to have your pet euthanatized is a serious one and seldom easy to make.
You may want to sit with your friend so you can pet and comfort her while the vet gives her the medicine. Many vets give the pet a shot of sedative before the euthanasia drug. The vet will explain to you what he's doing and where he's giving the shot. Some vets only use a sedative if the pet is frightened or can't relax. The shot can cause pain and the drug does have side effects, so talk to your vet about whether your pet should get it. If she's very sick and already quiet or has trouble breathing she may not need it.
