It's interesting that Muslims consider dogs unclean but not horses. It made me wonder if you can housebreak a horse. See the post below for the answer.
Mona Ramouni rides a SMART bus to her job with her guide horse, Cali, in Lincoln Park, Mich., Thursday, April 9, 2009. Ramouni lost her sight soon after birth, but she can't use a guide dog. Many Muslims consider dogs unclean, and Ramouni respects her parents' aversion to having one in their home.
