The owner bought him some senior feed, and now he'll eat every bit.
I read on another thread that horses may stop eating their grain if they have ulcers, but he eats his senior feed. He's also had his teeth floated quite recently. It makes since that he prefers senior feed, he is over 25 years old. I'm just curious about the sudden change of taste. Lol Any suggestions on why he won't eat the regular grain?
