Quality of life scale

Deciding to euthanize your companion animal may be one of the most difficult decisions you ever make. Often, well-loved pets are euthanized to minimize unnecessary suffering. The quality of animals’ lives is defined by their overall physical and mental well-being, not just one aspect of their lives. The following chart attempts to consider all aspects of your pet’s life. It is important to remember that all pets are different. What may be considered a poor quality of life for one may be different for another.

Higher numbers on this chart equal a better quality of life. This chart may help you to better visualize the general well-being of your pet. In some cases, even one item on the left-hand side of the chart (for example: pain) may indicate a poor quality of life, even if many of the other items are still positive. Some items or symptoms on the list may be expected side effects of the treatments that your pet is undergoing. It is important to discuss these symptoms and side effects with your veterinarian.
