The airline says it takes full responsibility

United Airlines says it takes full responsibility for the death of a dog on a flight.

An attendant forced the owner to put it in the overhead cabin for a three and a half hour journey from Houston to New York on Monday.

Last year, United had the highest number of animal deaths of any American airline.

The dog's owner Sophia Ceballos says the flight attendant said that he couldn't be in the main cabin because he would block the path and 'she put him in the overhead and closed it like it was a bag'
