When Robert Moore celebrated his 100th birthday in June 2023, he had some very special guests—more than 200 dogs! Dogs of all shapes and sizes attended Robert’s birthday party, and the man of honor petted every single one of them.

Robert’s daughter, Alison, decided to invite dogs to her dad’s party because she knew he would love to meet them.

“He just love, love, loves dogs,” Alison told the Washington Post. “Every dog he sees, he wants to pet. He has been like that his whole life.” 

Alison put a message on social media inviting friends and neighbors to bring their dogs to her home for the party. She wrote that she wanted to have a parade of dogs come up to her dad one at a time so he could meet each one. Many people shared the message with their friends. Alison guessed that about 20 or 30 dogs and their families would come to the party. 

On the day of the party, Alison was amazed to see a line of grown-ups, kids, and dogs stretching all the way down the street and around the corner. Some of the dogs even wore costumes! And some of the kids held cards they had made for Robert. One by one, the dogs got their chance to meet Robert, who sat in a chair in front of Alison’s house with a big smile on his face. 

“He pet every single dog that came through. It was so lovely,” Alison told USA Today. Many people have told Alison that they hope to do something similar for their own family members. “I hope this really does help spread joy. All these strangers coming together for my dad’s birthday party was all so lovely, and I hope we continue to have such events where everyone gathers and celebrates.”
