I worked horses for fourty years and walnut saw dust will indeed cause a horse to founder

Now just why is it that stubborn as they can be a mule has more sense than a horse .A horse will flounder it's self and a mule won't .If a mule can't pull a load it stops,a horse will pull it's guts out . Seems odd a mule has more horse sense than a horse .

Mule 101:  There is nothing stronger than a mules sense of self preservation.
