Wollero's owners no longer understood the world when the once well-behaved Hanoverian gelding Wollero became an unpredictable factor. Every rider who sat on him was brought back down to earth without further ado. The vet who was called in discovered that Wollero had severe pain in his back. Many therapies were tried, but nothing seemed to work. The owners could not afford a horse that could not be ridden and were looking for a solution. Their vet was able to help and asked us to take Wollero in.
