A trip to the Riverside Animal Shelter, which has euthanized close to 11,000 cats and dogs this year, was all it took to persuade him to adopt his new model, he said.
"I was amazed that I saw these beautiful, gorgeous puppies being put down mainly because there's no room to take care of them," Karapedian said. "Every dog that I save, every life that I save, I feel like I'm giving back to the community."
When he started the program, Karapedian said he was adopting out five to seven dogs a week.
"It's amazing because instead of going to the mall and spending $1,000, $1,500 or $2,000 on a puppy that's not spayed or neutered, that still needs vaccinations, they come to get these wonderful puppies who are a little older, already spayed or neutered, micro-chipped and vaccinated for a very low cost."
Karapedian, who has around 5,000 clients and has been in business for 10 years, adopts his dogs out for $150 to $350.
He said he couldn't have done it without the backing of Best Friends Animal Society, actress Katherine Heigl's animal rescue group, the John Heigl Foundation and community supporters, who gathered at his pet store in August to celebrate his success.
Clara Rossi, a longtime Pet Rush customer and close friend, said she is thrilled Karapedian is rescuing dogs.
"I hope that more stores do this and more animals get off the street," she said. "If you go to the shelters, you would sit there and cry because you would see all the animals that are being euthanized."
Karapedian, who holds mobile pet adoptions at the Kenneth Village Farmers' Market every Saturday, plans to work with the City Council to help ban puppy mill dog sales in Glendale and beyond.
