Vets said animals as large as giraffes can deteriorate quickly from arthritis.

They said they tried joint supplements, pain medications, anti-inflammatories, padded flooring, diet changes and trimming April’s hoofs to try to slow the disease’s progression, but her mobility kept declining, and she started spending a lot more time lying down.

“The severity of her condition has been outpacing our ability to control April’s comfort,” they said.

Giraffes commonly live up to 26 years.
