I am so sorry about Freckles! My prayers are with you and your family!
I don't want this to sound insensitive, I am not meaning it to sound that way. But I have to ask this, I am a mom of a boxer that had hemangiosarcoma and she died of it. We thank god we didn't even know she had it, see it was in her heart and we had no idea until the day she died. It was the worst day of my life and I would never wish it on anyone. That said, when you get this kind of news, how much is enough? I thank god everyday for the time I had with Britnee, for the laughter, hijinks & love she gave everyday. But not one time did I wish I changed my decision to let her die in my arms, that feeling she will forever remember looking into my eyes. Would you rather freckles remember the needles, shots, the time at the vet? Would you kick yourself in the rear knowing that she wanted to be done fighting and you refused to give up the fight for her? Just for it to happen that way anyway. You said she wouldn't get up for anyone would you rather her live that way? I would hate myself seeing Britnee live like that. That was not the Britnee I would've wanted to remember. Is there going to be a time that you can sit back and say, remember Freckles? We fought for her cancer, it was just too much we had to let her go? When is too much, too much? I once saw a police officer that said to me (when Brit was a pup he stopped me on the street), "I had a boxer she had kidney cancer. I kept her alive for me, we had her on dialisys (sp). I hate myself for it and I wish I never did it. Just remember that if Brit or your other boxer ever get sick don't keep them alive for you. If they are terminal let them go." I kept those words in my mind all though the years. Then when the time came for Brit, I had a choice, drain the pericardium (sack around the heart) and prolong her life for a short period of time OR give her up, in your arms. Let her go, she saw love, she saw a great life. She doesn't need to stay alive for me. I need to do this for her.
Think about this as you try more medicines that obviously aren't working, then think if you are ready to do something for her.
Please don't hate me, this is my opinion, what happened in my life, what I would do if she were mine.
