"When Jacob landed in Chicago, it was found that the airline agent LIED and he did not fit on the plane to Portland. He was then sent to a kennel over night, 20 HOURS, until the next flight out he could fit on."
According to KGW, Jacob ended up spending 20 hours in a kennel without food. The airline also reportedly didn't allow Considine's mother to provide food because the original trip was expected to be relatively short.
Considine said in the post that Jacob arrived in Portland disoriented and non-responsive. After the three-hour drive to Central Oregon, she said that his condition worsened.
Jacob eventually was taken to an emergency vet, where he died after several minutes of CPR.
