I am just coming in on this thread and have not read every post, so if I am repeating someone, I apologize.
First let me say I slobber over the Leopard Apps. Also, if it hasn't been said, Apps were a gaited breed way back in days of old.
There are still gaited Apps that descend from a stallion of the Nez Pierce Indian tribe. It is referred to as the Indian Shuffle.
On to my dislike for Apps (which is a long way from hate).
It is not really the App that I dislike. It's the morons that started breeding them in the 60's to produce flash and color.
As can happen in any breed, these people were so focused on color, that they forgot about the brains.
All the Apps I was ever acquainted with in the 60's & 70's were about 1/3 flake short of a full bale of hay.
They had quirky, more unpredictable than usual dispositions, and many times were just down right mean.
From my generation standpoint THAT is what gave Apps a bad name.
I do not keep up with Appaloosa, QH, or APHA breeding programs, but I have been told that the indiscriminate breeding simply to get a "lit up' horse has been or is being turned around.
Would I ever own an App? No because my heart is with the Arab/crosses and I now ride Tennessee Walkers (also in my heart) in order to keep riding
