OAP donkey Doughnut has died — despite huge efforts to help her overcome her medical problems.

The Isle of Wight Donkey Sanctuary announced her death today.

She had recently been taken to Liphook for veterinary treatment.

A spokesperson said: "Tragically, we have to announce that our greatly loved donkey Doughnut suffered a sudden relapse on site on Saturday and passed away yesterday, Sunday, September 13.

"There has been a massive amount of care and effort put into Doughnut by staff on site, by our vets, and by the Equine Vets at Liphook hospital. Tragically it has proven not to be successful but my word have we tried.

"Having come through surgery, Doughnut appeared to be on the mend. She had rejoined the OAP herd, was adjusting to her diet and was making positive progress.

"We believe the catastrophic events of the last 24 hours were caused by problems that could not be located on the various scans she undertook in hospital.

"Doughnut was a star. In her younger days she was an active therapy donkey who was well known among local schools and residential homes.

"She formed a happy partnership with Sooty and they even ventured to the mainland, spending several happy days at Wellington Vale home in Waterlooville.

"Doughnut could be readily identified by her tongue hanging out of the side of her mouth. She had very few teeth and needed frequent dental treatment to cope with food.

"Nonetheless she was enthusiastic about eating and was quick to let the staff know when it was meal time.

"The last 24 hours have been devastating for everybody associated with Doughnut.

"We tried everything we could to help her and give her chance of an extended life. Sadly it just was not to be."
