She named him Solovino, a Spanish word meaning "he came alone." And once Jesusita opened that door for him, he wouldn't leave her side - even as his steps began to falter.
Climbing the steep stairs that led to their door in Echo Park, Los Angeles, had become an ordeal for the old dog. His bones ached from arthritis; other ailments that came with aging plagued his every step.
Then, one day, Solovino could no longer take another step. It was time, at last, for Solovino to leave her side.
"We got a call on our hotline from the owner saying that she had a 17-year-old dog and needed help with humane euthanasia and transport," Kerry Armstrong, founder of Home Dog LA, tells The Dodo.
It was the kind of call Home Dogs LA was founded to take - the call the group hopes people will make before they consider an animal shelter.
A big reason why people surrender their pets to a shelter is because they feel they can no longer care for them. Maybe a cat is sick. Maybe, like Solovino, a dog has become too old and infirm. In any case, the real problem is financial hardship - and it leads some people to make crushing decisions.
