It can be really hard to find a black trail/pleasure type saddle!
We have a black leather endurance saddle $449.99
We also have several black show saddles if you are interested in a little bling ;)
I would be really careful with having a saddle dyed...if it isn't done right you will forever be staining your clothes/horse/pad.
Good luck in your search!
Feel free to PM with any questions!
