April 10 marks National Sibling Day, and for anyone who grew up with brothers and sisters, your childhood was no doubt full of shared secrets, rivalries, teasing, tears, and plenty of laughs. Siblings learn so much from one another — sometimes what to do, but often, what not to do. They play with each other, fight with each other, guide each other, and stick up for each other. All in all, they definitely make life more interesting!

We’ve rounded up a few photos of puppy “siblings” to celebrate this sacred bond, because who couldn’t use more puppies in their life?!
