history: My dog passed away of bone cancer. She was such a special dog.  My dog had bone cancer and we had to put her down. It was a very sad_comma_ but necessary decision.  it takes a strong and compassionate person to make that kind of decision.
current: It was very hard, but she was suffering. Our vet was very helpful and we did ask him if he thought it was too soon. He assured us that it was not. 
next: She had a happy life. I'm sure she understands.
