I have owned 2 full blooded and a hunting partner has a 1/2 dogo 1/2 bulldog.
There is not a lot of people in FL that have them and very few actually hunt with them. The one I had had a heart murmer and died at 3. It was taken to University of Florida and was told any white dog with a pink nose can have these problems. The breeder honored a Guarantee and gave me another pup. He is healthy as can be and never any skin or hearing problem. He did have a joint problems from growing big very fast.
More than anything they are big and eat a ton.
