Although our pets are only around for a certain part of our lives, for them, we’re their whole life. They’re with us from when they’re only a few weeks old right until the very end, and throughout that time they give us nothing but unconditional love. So when we discovered people who were celebrating their pet’s lives by posting pictures from the past vs now, we knew we had to share them with you. Get a box of tissues ready, as this might get emotional.
