On March 25th I did the same thing to my Luna , my dear 14 yr old yellow Lab..she was wagging her tail, laying her head in my hands, looking at me with trusting eyes, BUT she could barely walk, couldn't hold her urine, was in much pain..no quality of life left..and as our vet told us "dogs really do live for the moment" and she needed to be free from her misery..I cried, could barely get the breath to say good bye, kept whispering "I'm sorry, I love you"
Yes I DO know how you feel, but know what? It's fine now, she came to me in a dream just two nights ago, to my bed, laid her big ole head in my bed and was wagging her tail and walking with no pain! She left wet muddy paw prints on my floor all the way from the door! So I know she came back to help me..(In my dream)
So Don't you fret and feel bad, you did the right thing, your dog knows it and so does God above.
Bless you for loving your friend enought to let him go..
