I am so sorry that you have to go through this. It’s very tough to set them free but as the vet that helped us with Maya told me, is the most beautiful gift that we can give to them. I just went through the process with my beloved Maya and like others have mentioned, during my grieving process questioned my decision and start thinking that I had let her go too soon but then I remind myself why I did it. Unfortunately I knew that Maya was not getting any better, even though she was still eating, going for her walks and relatively happy, she was coughing up blood, her breathing was awful and she was having trouble to get comfortable. Maybe I could have kept her for a couple extra days but it would have been for me. She hated medication so I didn’t want to have her last days of her being uncomfortable because of the meds. Like Sally mentioned, write down your reasons so when you go back during your grieving process you don’t second guess yourself. There is no right or wrong decision, ultimately we do everything out of love and they know it. The vet also told me that dogs are really good about hiding their pain and of course that makes it even harder. I am sending you positive thoughts and Lots of love. Be sure that the whole tripawd famy will be there greeting Roman when he makes to the bridge.
