PontI'm really sorry for your loss - it's such a hard thing to go through. I lost my dog the day before Easter this year, so just a few weeks ago - pretty close to when you lost your bud. For me, he had a day back a few months ago where he stopped being able to walk, so we brought him to the vet. Definitely seemed like that was gonna be his last day. Luckily he was better after being put on some medications for the time-being, but it was mostly just for comfort at that point. I just considered all my time with him after that to be "extra time" which helped me really appreciate the time he had left.
My advice would be to remember you did your best. It's easy to have regrets and beat yourself up over things you could've done better but based on the way you speak about him, it's pretty clear you gave him a lot of love. Feel free to add me too, I am sure we're both dealing with some of the same feelings.
Damn man. Reading this made me cry so hard. It reminded me of what I went through leading to his last day. It all started with this "episodes" that I later found out were caused by the tumor in his heart bleeding between this layer around the heart and the heart itself. It would cause these episodes where he would collapse and all he could do was lay there and hyperventilate to try and breathe, as the pressure of the bleed pressed against his heart and made breathing difficult. I went through 2 vet visits, and then it got so bad I finally took him to a hospital/specialist where they quickly found diagnosed his issue. They tapped his chest and pulled out 1/3 of a liter of blood. This relieved his symptoms drastically and they sent us home. They told me the median life exptancy without any intervention for that cancer was 12 days. I did a lot of things to try and sustain his life and make him comfortable. But 4 days after we left the hospital he bled again and I couldn't take watching him suffer like that and took away his pain.
It is so traumatic going through all of that. Thank you for sharing your story with me.
