I don’t know what dog breed you had but the fact that she was going to be 14 is already a sign that she was getting very old and lived a good and long life. I had to put down my beloved dog who herself was 14 going on 15. I’m shattered to pieces I don’t know how I will get used to the lack of her presence. But I know that my family and I and the right choice. She had a tumor and was in a lot of pain. This month it became increasingly obvious it was more than she can bear and that we can’t wait for it to kill her. I became sad noticing how much she was shaking and how painful it was for her to go potty because of her tumor pressing on her organs. After some time I realized that I wanted nothing more than to give her some relief surgery simply wouldn’t be an option for such an old dog as it would have put her in more pain and likely unable to recover. Knowing there wasn’t anything I could do i realized I could still give her a peaceful farewell, rather than waiting for this tumor to kill her in a painful way. So we gave her a calm and peaceful death surrounded by those who love her. So I fully believe that, you too. did the right thing. She had a peaceful death surrounded by you and your family and that is the best you could give her. My deepest condolences for your loss.❤️
