Oh dear, my heart breaks for you. I am such an animal lover and can’t bear to see an animal in pain and I can clearly see you did everything you could! You gave that sweet dog a wonderful life and more love than she probably could’ve ever dreamed of! She lived a great, long, happy life because of you! It is human nature to think we are always in control of situations but most times we really  do not control life’s outcomes. It is normal to think if i had only done this or maybe if i didn’t do this or if that had happened etc. bc our mind so desperately wants to makes sense of this great loss and pain or for it not to be true! It is part of grieving! I know in my heart your dog is so grateful for everything you gave to her. Cherish her memory and it’s ok to be sad and have your feelings but recognize that just bc you feel you may have contributed to her death, that doesn’t make it true. Your sweet girl would want you to be happy and it’s obvious you had nothing but the best intentions when it came to her and her care. It will take time to grieve and process this but blaming yourself is not the answer. I’m grateful there are people in the world like you who care so much for our four-legged friends. <3
