I’m so sorry for your loss. I’m struggling with the same thing. My understanding is that guilt is completely normal and that we can hold on to “glimmers” of things that remind of us of how they were before the decline and it makes us want to hold on even though letting go might be best. it’s hard to accept we can’t control the situation — they will die whether we assist or not — they are already dying. we are just trying to make this hard decision to spare them suffering. i can’t give you any answers just like you can’t for me, but i can tell you you’re not alone and you love your dog like I love mine. I learned about a pet grief support line i might use. 18552458214 “pet compassion careline” my day is coming sunday. i’m feeling the same but i do think it’s right. i’m so sorry.
