The Yorkshire terrier clinging to life after his owner allegedly burned him died early Thursday.
The shock of the burns apparently damaged his kidneys, pancreas and other internal organs, veterinarian Elisa Mazzaferro said.
"He suffered cardiopulmonary arrest. He didn't suffer; he was comfortable."
Bobo suffered burns over his legs and other parts of his body after his owner allegedly hogtied him and set him on fire over a stove on Sunday. A neighbor saw the fire and alerted Lakewood police.
Relatives of Tanya M. Martin, 38, of Lakewood, say she suffers from mental illness.
Martin was formally charged Thursday with cruelty to animals and fourth-degree arson. She remains in custody at the Jefferson County Detention Center on $10,000 bond.
As recently as Wednesday, the Bobo hotline was sounding optimistic: "Bobo was resting comfortably today, greeting us and interacting with his surroundings," said the message. The message said veterinarians were hopeful that a special skin treatment could hasten Bobo's recovery.
On Wednesday, Mazzaferro brought Bobo into a hyperbaric chamber in Lakewood donated by animal lover Dr. Alex Thermos.
"It was very peaceful in there," Mazzaferro said. "We took a nap together."
But afterward, when surgery was done to remove some of Bobo's dead tissue, "it showed that some of the organs were failing," she said. "The burns we could see were only the tip of the iceberg." The failed organs were "the internal consequences from the external burns."
Mazzaferro said Bobo was given generous doses of pain medicine. Up to the end, "he was alert and responsive and very comfortable. He wasn't suffering."
Coloradans, stirred by the story of the burned dog, had donated more than $23,000 as of Wednesday afternoon for Bobo's care, said Ben Drotar, director of marketing for Table Mountain Animal Center. The average donation was $53.
"We'll more than likely be well over what was required for Bobo's care," Drotar said. The remainder will go into the Westy Fund, a pot of money to help abused animals.
I know these pictures are hard to look at, but this is what Bobo had to go through just because a woman had "mental problems?" Attachments are pictures of Bobo being treated and of the lady who did this horrible thing
