I've read an account from a gentleman who was dead for a half hour then re-entered his body, which was supernaturally healed. He went to heaven during that time and met Jesus and saw much. Spoiler alert but the man's childhood dog was there, full of joy to see his special human again.
Yes, that's how much God loves us. Your dog will be there to greet you. Make sure you make it to heaven! Our souls persist beyond the death of our earthly bodies. We all need to choose Jesus, form a serious relationship with Him. Repent. Forgive. Above all, love. Why would we choose anything else if we could choose eternity with our pups and our creator? Most choose the easy path which doesn't get you there. We all need to put ourselves last, others ahead of us, and Jesus first.
God bless you as you learn to live without your little buddy during the rest of this vapor of a life we live. I pray your path leads you to be reunited with her for all eternity one day.
