When the time comes, and we can clearly see that an animal is not living its best life anymore, do we have the right to help them transition? Is it what they want, and will they forgive us (or is forgiveness not required because it's what they want).
Quality of life can shift gently & gradually or radically. You may grieve the changes, yet quality of life can remain even if it looks quite different.
Another shift of perspective is to consult with your animal family member to ask them directly if they would like help with transition.
No fear of taking action prematurely.
No burden of making a decision solo (on behalf of your loved one).
No concern whether suffering is being prolonged.
End-of-life care becomes a process of honouring your animal family's wishes.
It doesn't make saying goodbye any easier, though you know the actions you take are respectful and supportive.
You're their advocate in the human world.
And yes. Forgiveness is not needed.
We tend to see everything through our own (species) perspective.
People are often surprised to hear how different (loving & freeing) their animal family member's point of view is.
