That's the worst thing about owning a pet. I couldn't tell you how many times I've had to go through that. Not fun.
At one time we practically had a zoo when my kids were little. Now we are down to two dogs and one is getting old already. It happens too fast.
And I guess that brings us to the next question. Will we see them again in Heaven?
There is a book on the subject called “Cold Noses At The Pearly Gates: A Book of Hope for Those Who Have Lost Pets”.
It is a comforting book and the author makes some good debate arguments that our pets can join us in Heaven if that is what our heart of hearts desires. Afterall God made them the first time, and its not to much for him to do it again.
