We have a coming 2 year old Mini Dexter bull. 
30" to 32" tall.
He's built like a tank. 
AMAZING personality. 
Easy to work with. 
Was halter broke, but he will follow anyone with a bucket of cubes. 

Current on shots (7way) and pour-on wormer. 
 

And a long yearling mini zebu bull.
Hes coming around to being friendly. Not mean in anyway, just hesitant about people. He will come up and take cubes from your hand. 
Current on shots (7way) and pour-on wormer.
30-32 inches tall.
Asking $500

Would consider trades.
