Client Comments
I have used Stallion AI for a few seasons now. My Quarter Horse Stallion, Toys Triple Chick (Rooster) loves his stays and he is looked after like royalty (which of course he knows he is!) I have found true professionalism in all who work there and everyone is just so friendly. I wouldn’t even consider sending my precious boy to anyone else. Also I can drop in at any time on the CCTV to see him, bless! I feel sending any stallion there give hiin a credibility which going to an elite establishment involves.— Christine Richards (Toys Triple Chick)
