The Cumbre Vieja volcano on the Spanish island of La Palma was spitting lava and ash since September 19, still with no sign of stopping.
The eruption caused the evacuation of thousands of people from their homes, destroyed buildings and forced some areas to become restricted areas.
After the devastation, drones captured footage of emaciated dogs on the island, prompting a surge of support from animal lovers across Spain.
Donations and initiatives were put in place, and a rescue mission began.
A photo of a banner circulating on social media, saying in Spanish: “Be strong La Palma. The dogs are fine. A-Team, ”hinted that the animals may have been moved.
The drone team confirmed that they could see part of the message from the sky, as well as human footprints.
“The banner is really there, only blown over by the wind, and we saw human footprints, so we understand that the dogs had been gone for a few days,” said general manager of drone operator Aerocamaras, Jaime Pereira.
Mr Pereira added infrared temperature measurements of the lava surface surrounding the yard, where the animals had stranded for weeks, showed it had cooled in some places to 40C-70C (104F -158F).
This means that it would be possible for someone to walk to their rescue.
“We knew something weird was going on when we checked all the areas they might have been hiding and found nothing,” he said.
“Now we just want to see the dogs, to check that they are okay and that they are the same that we were looking for. “

Smaller drones had delivered food packages to the dogs, but so far no one had been able to retrieve them.
Aerocamaras planned to send a 50kg cargo drone with a remote-controlled net to try and trap the dogs one by one and make them fly over the lava.
Canary Islands officials said on Sunday that there was no end in sight for the volcanic eruption after 40 tremors hit La Palma in one day.
