ABILENE, Texas — The Abilene Zoo is mourning the of an 11-year-old Maned Wolf.
The zoo staff made the "difficult decision" to euthanize Rosita due to declining health.
"Over the period of the last few weeks, animal care staff began seeing indications of health issues," the city said in a news release.
"We examined Rosita and treated her for tetanus as a preventative measure," said Dr. Stephanie Carle. "Unfortunately, her symptoms progressed."
Maned Wolves live up to 12 years in captivity.
Rosita arrived at the Abilene Zoo in 2010 and raised two litters of pups.
Two weeks ago, one of those pups, Sophia, returned to the Abilene Zoo.
Sophia was born in 2013 and was transferred to the Fossil Rim Wildlife Center where she raised her own litter of pups.
Sophia joins a new male, Cristiano, on exhibit as part of the Association of Zoos and Aquariums (AZA) Species Survival Plan.
Over the weekend Rosita was standing at the fence next to her daughter, Sophia,“ said General Curator Denise Ibarra. “The human side of you wonders if they recognize each other, even if for a short period of time.”
