Ryder means the world to Shamus Butler.
"He's my best friend, my companion, my partner, my son, my brother," Butler said about his dog. "He's everything to me, and I want to make sure that he's taken care of before anything. He gives my life purpose."
Butler, 28, has been homeless for about eight years. Wanderlust keeps him on the move around the country and so does following the Grateful Dead spinoff band Dead & Company. He adopted Ryder as a puppy nine months ago after the band's concert in Denver, and the two have been inseparable since.
On a recent Saturday morning, Butler spotted a banner for the group Street Dog Coalition outside the Episcopal Diocese of San Diego in Ocean Beach. Inside the courtyard, he found a table with bags of dog treats, food and pet jackets. There was also a team of veterinarians and volunteers ready to give exams, vaccinations and medication to prevent animals from getting fleas and ticks.
"I really appreciate it," he told the veterinarians after they administered medication for Ryder's cough, checked him for heart worms and gave him a handmade soft jacket. "You guys did a whole lot more than I expected."
Veterinarian Jon Geller started the coalition in 2015 to help homeless pet owners he saw around his practice in Fort Collins, Colo. Other veterinarians quickly joined him.
"The reason it's expanded so much is that veterinarians are saying, 'We want to do this,' " he said. "It's taken on a life of its own."
The coalition has expanded to more than 20 states.
