They are fantastic, and loyal. I had a 65lb Blue leopard Catahoula, that got in a fight with a 110+lb Rottweiler when I was a child because she thought the rotty was endangering us kids. Okie lost one tooth, but the Rotty was placed in the hospital for a week and had to get 13 stitches.
Also, is he registered? If so, if he has any Terra Cotta Catahoulas in his bloodlines, those were my dogs...LOL
