I moved up to a fancier horse last year because my horse just couldnt go higher in dressage. Don't get me wrong, I LOVED that horse, he was always so happy! Always forgave my mistakes. But he was my learning horse, my first horse, and he loved his job. Honestly, he didnt care for dressage, but he LOVED kids and being loved, not compotitions. So I sold him to a young girl and her mom who LOVE him, he gets spoiled rotten and is probably already a plump little horse, he thinks he's in heaven. And now I have a more serious horse that I love to death also (shes my heart horse) and she likes dressage, sometimes she's lazy, but she hates jumping. And she has the talent to tak me up the levels.
It depends on YOUR interest, and the best interest for the hrose. Does your horse love to jump? Is he happy doing that? Or would he rather be truckin' around a jumper ring with a little kid on his back?
You have to make the decision, no one else. :)
If there are no horses in heaven... im not going.
