Experiences with honoring a pet that is passing

I’ll be letting my sweet 14 year old dobe Sophie go this evening. Would anyone want to share ways they have honored or eased their passing to the next place? I’m really struggling and I’m having trouble coming up with the right touch. I’d like to concentrate on her ease of passing, calling my mom-her favorite person-to take her across and lastly for forgiveness from my dog for not giving her the amazing life she deserved. Any ideas would be appreciated. Thank you
