I have one Mustang, Hesa Pokee Poco. The Mustang stallion near my house bred with a friend's Quarterhorse mare. He isn't registered or anything, but I have learned more from this horse than any other horse that I have owned. The Mustang personality is so different from any other breed. They are an energetic breed, but they do have their lazy side.
Mustangs are very emotional and tempermental.
They have so many moods. You just have to wait and see what mood they are in each day. Poco is an exceptional horse. He is so beautiful. His tail is so long and gorgeous.
