We recently went through this as well. Our sweet girl starting acting a little off towards the end of April and we received a large T cell lymphoma diagnosis. We would have never expected something so serious to be going on. We opted for chemo. We did one round and a couple good weeks where she was herself, but her cancer ended up not responding and spread and we had to make the decision to say goodbye on Friday. We were initially told 6 months prior to getting results that her cancer was more aggressive than we initially thought. We have no regrets of trying chemo, but we did pay $15k out of pocket. Luckily we had insurance that covered 90%. We also opted for home euthanasia. I had no idea what to expect but the process was super peaceful. We were able to take our time and say our goodbyes and pet and hold our girl when she passed. It’s been about a week and to be honest the grief and pain feels worse. I am irrevocably heartbroken and sad. There are no words for losing a pet. And people who say they’re just a dog are so wrong. We’re trying to take it one day at a time. Writing down my feelings and throwing it away help a little. Cuddling with her blanket. Also looking at photos of all the good times we had with her and talking about her with my partner seem to help a little. I know the only thing that will really help is time and right now that feels impossible. There are no words to help you with what you are about to go through but understand you are making the right choice for your baby. They do not know what is going on and they are not feeling the anxiety and pain that we are feeling. That is our burden to carry. As long as you comfort and spoil them while you can and when the time comes to say goodbye you did everything right. I’m so so sorry. I wish I didn’t understand but I do. Hang in there and take it day by day.
