Delta Air Lines said on Saturday it is investigating the death of a dog that died in one of its plane's cargo holds during a cross-country flight.
Alejandro, a Pomeranian, was traveling from Phoenix to Newark via Detroit this week, where he was found dead.
A lawyer for the owner of Pomerania, Evan Oshan, who also represented the family of Kokito, the French bulldog who died on the United flight, told NBC 4 New York that the dog's owner is trying to recover the remains of Alejandro.
"We know that pets are an important member of the family and we focus on the welfare of all the animals we transport," Delta said in a statement.
"Delta is conducting a thorough review of the situation and they have been working directly with Alejandro's family to support them as we can," the airline said. "As part of that review, we want to get more information about why this may have happened to make sure it does not happen again and we have volunteered for Alejandro to be evaluated by a veterinarian for more information."
Transportation of pets on airlines has attracted more scrutiny in recent months, after several deaths of animals that were en route to their destinations died. The increase in attention occurs in a backdrop of an increasing number of animals traveling in cabins.
United Airlines said last month that it would no longer accept other animals besides cats and dogs, and banned dozens of dog breeds from its cargo hold. That change came after the death of a French bulldog puppy who died after being placed in a higher compartment, and two other dogs that the airline flew to the wrong destinations.
U.S. The airlines transported 506,994 animals last year, according to the Department of Transportation. Delta transported 57,479 animals in 2017, and said two of them died.
