im training p.k. for halter this year. he is my 2 yr old quarter horse gelding. what is the best way to get muscle on him? how muscled up does he have to be? how long will it take to get him into shape considering this is his first year of ever being handled. he is quite chubby right now with a lot of baby fat!i cannot pony him because he doesnt like it and he goes soooo slow! and he pulls back and doesnt enjoy it much. i think its because the only horse i have to pony him with is a half tn walker which trots fast.any help would be great! should i give him any extra supplements to help with energy? he is my first halter horse so i dont know a whole lot about the event!
