I don't have anything to base it on for sure, but I really want to believe we will be reunited with our pets. The cool thing I think about is alot of other animals too, like lions, laying side by side with sheep. I think God's creation is absolutely wonderful here (mountains, oceans, rainbows, clouds, sunsets and sunrises, DOGS! etc.), so I can't imagine heaven, where there is no sickness or pain, where we have new "bodies". What love God has for us to give us so much! We haven't taken really good care with what he has given us, but his creation never ceases to amaze me!
