Aww I'm so sorry for Audrey and for what you must be going through with worry for Audrey's future. I lost my Jack Russell Oreo almost 3 years ago at the age of 14, and she was diagnosed with cancer 2 years before she died. I was also faced with the future options and decisions of what we would do as she got older and sicker. The vet told us the same thing she wasn't in any pain, and she wasn't suffering. We decided to keep her with us until we had no other choice to make a decision, as long as she didn't have pain, wasn't suffering, and had quality of life, the vet said she could live with cancer for a while just like a person can. She slept a lot, she was an old girl after all, but she still got excited to go outside and greeted us with her little wiggly butt, and sometimes still liked to play, although not too much, her appetite was less, but she did eat, we had always fed her Go Natural kibble, but switched to a wet food to make it easier for her. She got to the point where we had to think about letting her go, she developed an ulcerated sore on her face, and it wouldn't heal, her back end and legs were wasting away, and she couldn't go up the stairs anymore. we were going to take her to the vet to have her put down after the weekend, but on the Saturday morning before we woke up and I went into the kitchen, I saw her in her crate, and she didn't get up like she usually did, I said her name, and she didn't move, I knew she had gone, but couldn't bear to see her. I called to my husband and asked him to come down, I told him I thought Oreo was gone, he said no she's sleeping, but when he checked he said she was gone. We wrapped her in a towel, and he carried her down to the river, way down the trail where we used to walk, dug a hole under a tree that was off the trail in the woody area, and buried her under the tree. We figured why take her to the vet when she was already gone, and they would cremate her, this way she was where she loved to walk. We never had to make that decision, as she went in her sleep, and hopefully peacefully. I wish I could have held her, talked to her before she died, but I hope she didn't feel it and just slept in. I don't know if we made the right decision, by keeping her with us, but she did seem happy, and not in pain, and if I thought she was suffering I would have made the decision of what was best for her, and I would have put her down at the vet when I took her there, but in the end didn't have to make that heart wrenching decision. I know Audrey is happy with you, and she feels loved and you love her, and when the time comes you and your family along with your vet will make the best decision for her, and what is best for her, and you'll make it with love for her. Audrey can live with cancer and be okay, and I pray that you have more quality time with Audrey. Sending love hugs and prayers to Audrey and your family. Please keep us posted on how she's doing, and if you need to reach out to any of us, to vent or talk, or even cry, we are all here for you. Take care Hun
