The old myth that small bulls can't breed large cows, again.
Brenn of Paradise was a 7 month old short-legged Dexter bull when he bred a small herd of dairy cows. No misses.
Rainbow Hills Ivanhoe was a short legged Dexter bull that successfully bred a herd of 35 Angus cows for years, making "Dangus" beef calves.
No matter how short the bull, the cow can reach him when she's ready.
