God this just tears me up. My sweet little 15 year old pug has prostate cancer. I don't know if I can handle this! The vet said that ethically she had to tell me that there were options available, like chemo and radiation. But she said that if he were her dog, she would just let nature take it's course. She said he has spirit, and that he's happy and not in any pain, so I'm thankful for that, but this is just tearing me up. I look at his sweet little monkey face, and start to cry.
I have lost a dog to cancer. No amount of "I am sorry", or "I know how you feel" will ever be enough or even begin to cover what you are feeling. But understand that you all shared some of the best moments of your life, and that is something that won't ever go away. My heart goes out to you during this time.
My condolences, I just went through this about a month ago when I lost my 12 1/2 yr Cocker to a fast growing lung and brain cancer, it only took about 5 days. I am sorry to hear about your pug and remember to celebrate the joy you received and that if you caould go back to when you adopted you pug, you would do it all over again.
