Quality of Life Assessment

When to Consider Euthanasia
This is the hardest decision you'll make. Consider euthanasia when:
- When pain cannot be managed
- When basic functions fail
- When suffering outweighs comfort
Remember: Choosing euthanasia to prevent suffering is an act of love, not giving up.
Making Them Comfortable
If you have time to prepare, or if you're providing hospice care:
- Provide soft, comfortable bedding
- Keep them close to family
- Maintain a calm environment
What to Expect
Whether death comes naturally or through euthanasia, knowing what to expect can help you prepare emotionally.
Natural Death
Natural death in dogs often involves a gradual decline over hours or days. Breathing becomes irregular, they may lose consciousness, and eventually their heart stops. This can be peaceful or distressing depending on the underlying condition.
Euthanasia
Euthanasia is typically a two-injection process. The first injection is a sedative that makes your Cavalier King Charles Spaniel sleepy and unaware. The second stops the heart - it's painless and takes only seconds. You can be present to comfort them until the end.
