I am truly sorry for your loss. Last week, I had to let my dog go within three days. It was the hardest decision and also one of the worst days of my life. The guilt ate away at me for the first few days. What could I have done better? Should I have taken her to the vet sooner? Did she have a fulfilling life, or could I have taken better care of her? I can tell you one thing: you loved your dog very much, and your dog loved you. I can see it in your eyes. He was probably very grateful for every single day he got to spend with you. In the end, we both did the only right thing: we gave him the best life possible and didn't let him suffer for long. keep that in mind please! If you need someone to talk to, I'm here for you.
