If you get one with high prey drive you must extensively train it so it doesn't chase everything. Another thing about these dogs is they did not just bay they attacked and were used as catch dogs. I don't know what your states specifics are about using dogs.
I looked into many different breeds including the Karelian and opted for a cane corso. I use him as a treeing dog.
