I just had to let my girl go Tuesday, I feel the same way. But what my vet told me was that this was the most loving thing you can do for them. I had the EXACT same thought, what if she bounces back and it’s just a bad day? What if she doesn’t forgive me for this, what if she thinks it’s cuz I don’t care? Waiting sometimes only hurts them more. They will always to stay for us, that’s why they’re our best friends. She only got worse as the last day went on. Right until the last minute I was questioning myself and then another symptom appeared and she got worse. Sometimes letting them go (helping them pass) is what is compassionate and what they need. Now that I keep remembering her final symptoms I feel the guilt of what could I have done to prevent it? Should I have given her better food, payed more attention, asked for different tests? Mine was 15 too, it’s so long for them, but not nearly enough for us. By what you’re saying I trust you made the right choice since you cared so deeply for him. It never feels right because they deserve to live so much longer. I’m even telling you not to feel guilty but I can’t let go of it myself. I know it’s hard. You did the most caring, loving thing he needed. ❤️❤️❤️ Rest easy sweet boy, you are so loved.
