Splashing in water is Murphy's absolute favorite.
"I don’t know what I'm going to do without him, but I really believe he’s going to show up," said Morris Collins, whose service dog is missing.
He hopes Murphy returns soon before time runs out.
"I have esophageal cancer. I don’t know how much time I have, short or long, whatever it’s going to come to," he said.
Murphy suddenly went missing three months ago when Collins was rushed to the hospital.
"Murphy took off after me in the ambulance. You can’t get any more dedicated than that," Collins said.
Now that Collins is home on hospice, he's dedicating his time to finding him.
He says he needs Murphy to enjoy life's ups and to fight its downs.
"I’m looking for that ray of hope that I’m going to get him back," he said.
People from as far as New York have been searching for him.
"And other parts of the country and I just think it’s just awesome that so many people care," said Collins.
Collins feels the emptiness in his heart without Murphy.
"It’s like waiting for the next shoe to fall, to find out Murphy is dead would be very crushing," he said with tears in his eyes.
What is even more heartbreaking he says to live the rest of his life without him.
"You can’t replace him you can only hope for the best and my hope is that this reaches out and touches that person and they bring him back," Collins said.
