SAN DIEGO (KGTV) — The San Diego Zoo Safari Park said goodbye to one its most beloved animals last week.
Raina, the domestic dog and companion animal to Ruuxa the cheetah, died following several health issues over the past few years, according to the park.
The dog was being cared for by the park's staff and the "difficult decision was made to compassionately assist with her passing."

"Please join us in expressing condolences to the many San Diego Zoo Global staff members, volunteers and guests who will be feeling this loss. Please also join us in thanking the Veterinary Specialty Hospital for their support and treatment of Raina over the years," the park wrote on Facebook.
Raina had helped her cheetah friend learn to run again after having corrective surgery on his legs. Ruuxa, in turn, helped Raina battle an aggressive tumor and continue to live a happy life.
Ruuxa won't be without a canine companion, though. Rae, another canine helper, will continue to socialize with the cheetah.
