In this current world, it’s probably for the dogs’ sakes that they don’t live that long. They’d be wondering after awhile why they were supposed to like us so much, if they lived too long.
Now, after we’re made perfect by God and the animals come back, that’s going to be a far better time for all of us.
I’ve often wondered if part of God’s plan is for us to be reunited with our critters we’ve loved and cared for. Some say no, some say yes. I sure hope so!
