The Zoo Granby announced that one of its female dholes was euthanized due to respiratory problems. The Zoo discovered that there was a cancerous cell near the lungs. The Zoo made the decision to euthanize her to end her suffering. But the Zoo didn't announce who the dhole that passed away was, so we do not know. The group is now down to 2.4 individuals.
Here is the reply in the comments from the Zoo(Translated)
You are correct: the dhole pack previously consisted of seven individuals, two males and five females. During a routine checkup, one of the females, who was showing signs of respiratory problems, was examined more closely. A large cancerous mass near her lungs was unfortunately detected. To avoid unnecessary suffering and respect her well-being, our veterinary team made the difficult decision to euthanize her. Thank you for your interest and concern for our animals.
