You realize your pet will die and face the decision to euthanize or let the disease take its course. Owners know their pets better than anyone else. Changes in the quality of life of the animal will indicate to them that it's time. These signs differ with the owner's and animal's personalities and needs. They might include a lack of appetite, inactivity, a glazed look.
Diseases sometimes cause pets a lot of pain, which distracts pets from doing what they love.
The euthanasia procedure varies. Some veterinarians give you the option to euthanize your pet at home, in a garden, or in a place where you've spent a lot of time with the animal. Others do euthanasia only in the clinic. The typical euthanasia is an overdose of anesthesia that suppresses brain activity and stops the heart so that the animal doesn't feel any pain. Once the heart and breathing stop, death follows shortly.
