A few days later, Katherine took to Instagram to share a few pics of her dogs Maverick and Champ – taken by sister Christina Schwarzenegger – in honor of National Dog Rescue Day.

“It’s a day to celebrate my love for my Angews ! #nationaldogrescueday This sweet boy is the best little pup ever and has taught me so much about responsibility, myself and of course, about unconditional love,” Katherine wrote. “I love all pups, no matter where they are from, but if you haven’t been able to experience the love of a rescue dog, do yourself a favor and try it! You can foster to try it out like my sister and I did, you can volunteer and you can be a voice for the voiceless!”

Katherine continued: “The world of animal adoption is such a beautiful and rewarding one and I’ll keep spreading the word until my 4th grade dream comes true, where all the dogs and cats on the earth having loving homes ♥️ I love you my Angews! (Ps pics of Mav and champ by Christina. So talented)”
